R&S®RTO Acquisition and Setup Basics 2 Acquisition and Setup This chapter describes the horizontal and vertical settings as well as the acquisition and probe setup. 2.1 Basics This chapter provides background information on the essential settings in the vertical and horizontal systems, on acquisition setup and probing. 2.1.1 Vertical System The controls and parameters of the vertical system are used to scale and position the waveform vertically. 2.1.1.
R&S®RTO Acquisition and Setup Basics Fig. 2-1: Input range and resolution of the ADC With R&S RTO, you can work with multiple diagrams, and each diagram obtains the full vertical resolution, no matter where the diagram is placed. Therefore, use a separate diagram for each waveform instead of the traditional setup that arranges the waveforms side by side in one diagram. Fig. 2-2: Traditional setup of multiple waveforms in one diagram: reduced resolution User Manual 1316.0827.
R&S®RTO Acquisition and Setup Basics Fig. 2-3: R&S RTO setup of multiple waveforms in separate diagrams: best resolution 2.1.1.3 Bandwidth For analog applications the highest signal frequency determines the required oscilloscope bandwidth. The oscilloscope bandwidth should be slightly higher than the maximum frequency included in the analog test signal to measure the amplitude with very little measurement error.
R&S®RTO Acquisition and Setup Basics 2.1.2.1 Sampling and Processing The A/D converter samples the continuous signal under test at specific points in time and delivers digital values called ADC samples. The rate at which the converter is working is the ADC sample rate, a constant value usually specified in GHz: fADC = 1 / TI The digital ADC samples are processed according to the acquisition settings. The result is a waveform record that contains waveform samples and is stored in the waveform memory.
R&S®RTO Acquisition and Setup Basics Fig. 2-4: Waveforms acquired with different sample rates This means that the sample rate must be set to a value 3 to 5 times the fastest frequency component of the signal. A higher sample rate increases signal fidelity, increases the chance to capture glitches and other signal anomalies, and improves the zoom-in capabilities. 2.1.2.2 Acquisition Settings The sample rate can be the same as the constant ADC sample rate, or higher, or lower.
R&S®RTO Acquisition and Setup Basics 2.1.2.3 Acquisition Control You can run the R&S RTO in two ways: ● Continuous: the instrument acquires data until you stop it manually. ● NxSingle: the instrument samples and processes a specified number of acquisitions. The determining point of an acquisition is the trigger. It defines the time-zero point in the waveform record. The instrument acquires continuously and keeps the sample points to fill the pre-trigger part of the waveform record.
R&S®RTO Acquisition and Setup Basics 2.1.3 Horizontal System 2.1.3.1 Parameters of the Horizontal System The control parameters of the horizontal system are tightly connected. Thus, changing one parameter affects the other parameters as well. The mathematical dependencies can be summarized as follows: The time scale can be changed, all other parameters are adjusted automatically. The number of divisions is 10, this is the only constant parameter.
R&S®RTO Acquisition and Setup Basics Two parameters set the position of the horizontal acquisition window in relation to the trigger point: reference point (time reference) and trigger offset. With these parameters you choose the part of the waveform you want to see: around the trigger, before, or after the trigger. 2.1.4 Probes A probe connects the signal source (DUT) to the oscilloscope, and delivers the signal to be measured. It is the essential first link in the measurement chain.
R&S®RTO Acquisition and Setup Basics 2.1.4.1 Voltage Probes The following table provides an overview on common voltage probes and their usage.
R&S®RTO Acquisition and Setup Basics If you use passive probes, remember some recommendations: ● Use a probe recommended for your oscilloscope model. ● Use a ground lead as short as possible to minimize the effect of ground lead inductance. The resonance frequency can be much lower than the system bandwidth and thus can affect the measurement results, in particular, if you measure steep edge rise times. ● Select a probe that has a bandwidth of 5 to 10 times the highest frequency being measured.
R&S®RTO Acquisition and Setup Basics length on both paths. It is also immune to interference and noise and occupies only one input channel. A differential probe has three sockets: the positive signal socket (+), the negative signal socket (-), and the ground socket.
R&S®RTO Acquisition and Setup Setting Up the Waveform 2.2 Setting Up the Waveform This chapter contains the fundamental procedures for setting up the acquisition and adjusting the channel waveforms. 2.2.1 Setting Up the Signal Input with Autoset Autoset is the solution for the major part of routine test-setup. It is also a good start if you need to use more complex trigger settings.
R&S®RTO Acquisition and Setup Setting Up the Waveform 2. Select the "Enhancement". If "Interpolated time" is set, select also the "Interpolation mode". Enhancement affects all waveforms of all channels. The instrument uses enhancement settings if the "ADC sample rate" is less than the "Sample rate"; otherwise these settings are ignored. 3. To configure the waveform-specific acquisition settings, select the "Channel" tab and activate the waveform.
R&S®RTO Acquisition and Setup Setting Up the Waveform To acquire a limited number of acquisitions 1. On the "Trigger" menu, tap "Trigger Events Setup". 2. In the "Control" area, select the "Normal" trigger mode. 3. Enter the number of acquisitions in the "Average count" field. 4. Press the RUN N×SINGLE key on the front panel. You can stop the running acquisition before it is finished by pressing the key again. 2.2.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup For details on filter settings and dependencies, see chapter 2.3.4, "Digital Filter Setup", on page 49. To filter the input channels only 1. On the "Vertical" menu, tap "Digital Filter Setup". 2. Set the "Trigger coupling" to "Off". 3. Select the "Characteristics" - the filter type - for channel 1/2 and for channel 3/4: Highpass or Lowpass. 4. Enter the "Cut-off" frequency for each filter. 5.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Time scale Sets the horizontal scale for all channel and math waveforms in seconds per division. Increase the scale to see a longer time interval of the waveform. Decrease the scale to see it in more detail.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Restrict offset to acquisition range Ensures that the trigger occurs within one acquisition cycle. If enabled, the trigger cannot be set outside the waveform diagram. SCPI command: TRIGger:OFFSet:LIMited on page 489 Roll mode Configures the roll mode for slow time bases: Mode ← Roll mode Activates the automatic roll mode. If set to "Auto", the instrument activates the roll mode under specific conditions.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Sample rate Sets the number of recorded waveform points per second. The sample rate is the reciprocal value of the resolution and thus also depends on the acquisition time and the record length. It considers the samples of the ADC, the additional waveforms points resulting from resolution enhancement (interpolation and equivalent-time sampling), and the reduction of waveform points by decimation. See also: ● chapter 2.1.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Acquisition time Shows the time of one acquisition, that is the time across the 10 divisions of the diagram: Acquisition time = Time scale * 10 divisions Changing the acquisition time changes the time scale too. SCPI command: TIMebase:RANGe on page 429 Resolution / Record length (Time scale dependency) You can choose to keep constant either the resolution or the record length when you adjust the time scale or acquisition time.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Channel-dependent settings The "Decimation" and "Wfm arithmetic" are specific for each waveform. Make sure to select the channel tab first, then set up the waveforms. Resolution enhancement If the ADC sample rate is too slow to capture sufficient samples to achieve the required resolution, the sample rate can be increased by adding calculated points to the waveform record. The enhancement method is the same for all channels and waveform.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup "Equivalent time" This method requires repetitive, stable signals and is not suitable for random and non-repetitive signals. It is used to capture fast signals whose frequency components are higher than the "ADC sample rate". Equivalent-time sampling constructs a picture of a repetitive signal by capturing a little bit of information from each repetition.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Decimation Decimation reduces the data stream of the ADC to a stream of waveform points with lower sample rate and a less precise time resolution. The R&S RTO uses decimation, if the waveform "Sample rate" is less than the "ADC sample rate". In this case, enhancement settings are ignored. The decimation mode ist waveform-specific, you can select another mode for each waveform.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Reset Now Forces the immediate restart of the envelope and average calculation for all waveforms, ignoring the reset settings.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Fig. 2-5: Normal acquisition with blind time With Ultra Segmentation, a number of triggered acquisitions is captured very fast, with hardly any dead time between the acquisitions. The data is processed and the waveforms are displayed when the acquisition of the series has been completed.

R&S®RTO Acquisition and Setup Reference for Acquisition and Setup 50 Ω DC 1 MΩ DC AC Coupling Selects the connection of the channel signal determining what part of the signal is used for waveform analysis and triggering. In addition to coupling, the signal can be filtered for high frequency rejection, see chapter 2.3.4, "Digital Filter Setup", on page 49. "DC 50 Ω" Connection with 50 Ω termination, passes both DC and AC components of the signal.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup "800 MHz, 200MHz, 20MHz" Frequencies above the selected limit are removed to reduce noise at different levels. SCPI command: CHANnel:BANDwidth on page 439 Position Moves the selected signal up or down in the diagram. The visual effect is the same as for Offset but the waveform is adjusted at a later time in the signal flow. While the offset sets a voltage, position is a graphical setting given in divisions.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup 2.3.2.3 Coupled Channels Channel coupling sets the vertical settings of the coupled channels to the values of the active channel. If two or more channels should have the same vertical settings, you can set them at once by coupling the settings of these channels. Channel coupling affects all vertical settings that are adjusted in the "Channels" tab: vertical scale, position, offset, bandwidth, coupling, and ground. 2.3.

R&S®RTO Acquisition and Setup Reference for Acquisition and Setup For detected active voltage probes, manual settings are not possible. Current probes are not recognized automatically but the parameters of R&S current probes (R&S RT-ZCxx) are known to the instrument. On the "Manual" mini-tab, select the probe type with "Predefined probe". The correspondent "Vertical unit" and the "Manual gain" are set.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup Auto Zero, AutoZero DC offset, Use AutoZero Differences in DUT and oscilloscope ground levels may cause larger zero errors affecting the waveform. If the DUT is ground-referenced, the Auto Zero function corrects the zero error of the probe to optimize measurement results at small signal levels.The validation limit depends on the probe attenuation because probes with high attenation often have to compensate high offsets.
R&S®RTO Acquisition and Setup Reference for Acquisition and Setup ProbeMeter: Enable Enbles the integrated R&S Probe Meter of active R&S probes. This voltmeter measures DC voltages between the probe tip and ground connection with very high precision and enables ground-referenced measurements of voltages.

R&S®RTO Triggers Basics of Triggering 3 Triggers 3.1 Basics of Triggering Triggering means to capture the interesting part of the relevant waveforms. Choosing the right trigger type and configuring all trigger settings correctly allows you to detect various incidents in analog, digital, and logic signals. Trigger A trigger occurs if the complete set of trigger conditions is satisfied. It establishes the time-zero point in the waveform record.
R&S®RTO Triggers Basics of Triggering ● Trigger type and its setup ● Qualification Trigger sequence A complex trigger sequence joins two separate events with a delay time and a reset time or reset event. This combination is called "A → B → R" trigger sequence. Similar setups are also known as multi-step trigger or A/B trigger. The combination of one event with holdoff conditions defines a simple "A only" sequence.
R&S®RTO Triggers Setting Up the Trigger 3.2 Setting Up the Trigger This chapter provides step-by-step procedures for the important stages of trigger setup. The dialog boxes and settings are described in detail in chapter 3.3, "Reference for Triggers", on page 57. 3.2.1 Configuring the Trigger Event Prerequisites: ● Horizontal and vertical settings are set appropriately to the signals. ● The acquisition is running, the RUN CONT key lights green. For details on event settings, see chapter 3.3.
R&S®RTO Triggers Setting Up the Trigger Alternatively, tap the "Trigger" menu and then "Trigger Position". 2. Set the "Reference point" and the "Trigger offset". If you want to set the trigger position outside the waveform display, disable "Restrict offset to acquisition range". 3.2.3 Using Holdoff Holdoff conditions define a waiting time after the current trigger until the next trigger can be recognized. Holdoff is an optional setting to the A-event.
R&S®RTO Triggers Reference for Triggers 8. Additionally, you can define a reset condition: "Enable reset by timeout" and/or "Enable reset event". The sequence restarts with the A-event if no B-event occurs and the reset condition is fulfilled. a) If "Enable reset by timeout" is selected, enter the time in "Reset timeout". b) If "Enable reset event" is selected, tap the "R Event Setup" button and set up the reset event. The trigger types and settings are restricted dependent on the A and B event settings.
R&S®RTO Triggers Reference for Triggers This is the critical part of the oscilloscope setup to capture the relevant part of the waveform. ● Trigger mode: "Trigger mode" on page 85 ● Trigger position: chapter 3.3.5, "Trigger Position", on page 83 Optional settings are: ● Noise rejection settings: chapter 3.3.3, "Noise Reject", on page 79 ● Trigger sequence, a combination of two trigger events: chapter 3.3.
R&S®RTO Triggers Reference for Triggers Additionally, you can let the R&S RTO find the trigger level, set the trigger levels to the same value for all channels and enable trigger qualification. These settings are located under "Trigger type dependent settings". Ch1 Source Selects the source of the trigger signal for the current trigger event. The source can be one of the input channels, a serial bus, or an external analog signal connected to the External Trigger Input on the rear panel.
R&S®RTO Triggers Reference for Triggers ● ● ● ● ● Interval, see page 70 Slew Rate, see page 71 Data2Clock, see page 72 Pattern, see page 74 Serial Pattern, see page 75 Restrictions: ● If the external trigger input is used, only edge trigger is available. ● For the B-event, only edge trigger is available. ● For the R-event (reset), the trigger types and settings are restricted dependent on the A and B event settings. The instrument provides only possible, reasonable combinations.
R&S®RTO Triggers Reference for Triggers "Lowpass" Frequencies higher than the "Cut-off" frequency are rejected, lower frequencies pass the filter. You can adjust the "Cut-off" frequency, the default is 50 kHz. SCPI command: TRIGger:ANEDge:FILTer on page 458 TRIGger:ANEDge:CUToff:HIGHpass on page 457 TRIGger:ANEDge:CUToff:LOWPass on page 458 Find level Sets the trigger level automatically to 0.5 * (MaxPeak – MinPeak). The function is not available for an external trigger source.
R&S®RTO Triggers Reference for Triggers Fig. 3-2: Standard width trigger ThrRising = ThrFalling = Trigger thresholds for rising and falling edge are the same. The instrument misses the falling edge at T=0,27 because the signal stays below the hysteresis threshold. No trigger occurs. The robust trigger inserts a shift by the hysteresis value between the trigger threshold for the falling edge and the trigger threshold for the rising edge.
R&S®RTO Triggers Reference for Triggers If the trigger source is a channel signal, the edge trigger uses the digitized trigger signal. This signal can be qualified and filtered with the DSP filter. If the trigger source is the EXT TRIGGER INPUT, the analog trigger signal is used, and the coupling and filter for this signal is set directly in the trigger setup. Slope Sets the edge type for the trigger event. "Positive" Selects the rising edge, that is a positive voltage change.
R&S®RTO Triggers Reference for Triggers Polarity Indicates the polarity of a pulse, that is the direction of the first pulse slope. "Positive" Selects positive going pulses. "Negative" Selects negative going pulses. "Either" Selects both positive and negative going pulses. SCPI command: TRIGger:GLITch:RANGe on page 460 TRIGger:RUNT:POLarity on page 462 Range Selects which glitches are identified: shorter or longer than the specified "Width".
R&S®RTO Triggers Reference for Triggers While the width trigger can only analyze either positive or negative polarity, searching for a width is also possible for both polarities at the same time ("Either"). Polarity Indicates the polarity of a pulse, that is the direction of the first pulse slope. "Positive" Triggers on positive going pulses. "Negative" Triggers on negative going pulses.
R&S®RTO Triggers Reference for Triggers Trigger level Sets the voltage level for the trigger event. You can also drag the trigger level marker on the display (TA or TB on the right edge of the display). The range of the trigger level is limited in a way so that always a hysteresis for stable trigger conditions is available. SCPI command: TRIGger:LEVel[:VALue] on page 455 3.3.1.5 Runt A runt is a pulse lower than normal in amplitude.
R&S®RTO Triggers Reference for Triggers Range Selects how the time limit of the runt pulse is defined: "Any runt" Triggers on all runts fulfilling the level condition, without time limitation. "Longer" Triggers on runts longer than the given "Runt width". "Shorter" Triggers on runts shorter than the given "Runt width". "Within" Triggers if the runt length is inside a given time range. The range is defined by "Runt width" and "±Delta".
R&S®RTO Triggers Reference for Triggers Vertical condition Selects how the signal run is compared with the window: "Enter" Triggers when the signal crosses the upper or lower level and thus enters the window made up of these two levels. "Exit" Triggers when the signal leaves the window. "Stay within" Triggers if the signal stays between the upper and lower level for a specified time. The time is defined in various ways by the Time condition.
R&S®RTO Triggers Reference for Triggers For the ranges "Shorter" and "Longer", it defines the maximum and minimum time lapse, respectively. SCPI command: TRIGger:WINDow:WIDTh on page 467 ±Delta Defines a range around the "Width" value. SCPI command: TRIGger:WINDow:DELTa on page 467 3.3.1.7 Timeout The timeout trigger event checks if the signal stays above or below the threshold voltage for a specified time lapse.
R&S®RTO Triggers Reference for Triggers 3.3.1.8 Interval The interval trigger analyzes the time between two pulses. While the interval trigger can only analyze either positive or negative polarity, searching for an interval is also possible for both polarities at the same time ("Either"). Polarity Indicates the polarity of a pulse, that is the direction of the first pulse slope. "Positive" Triggers on positive going pulses. "Negative" Triggers on negative going pulses.
R&S®RTO Triggers Reference for Triggers Interv. width Defines the time between two pulses. SCPI command: TRIGger:INTerval:WIDTh on page 469 ±Delta Defines a range around the "Interval width" value. SCPI command: TRIGger:INTerval:DELTa on page 470 3.3.1.9 Slew Rate The slew rate trigger, also known as transition trigger, can detect fast or slow edges selectively.
R&S®RTO Triggers Reference for Triggers Lower level Sets the lower voltage threshold. When the signal crosses this level, the slew rate measurement starts or stops depending on the selected slope. SCPI command: TRIGger:LEVel:SLEW:LOWer on page 471 Range Selects how the time limit for the slew rate is defined. The time measurement starts when the signal crosses the first trigger level - the upper or lower level depending on the selected slope - and stops when the signal crosses the second level.
R&S®RTO Triggers Reference for Triggers Clock source Selects the input channel of the clock signal. SCPI command: TRIGger:DATatoclock:CSOurce[:VALue] on page 473 TRIGger:SPATtern:CSOurce[:VALue] on page 477 Clock edge Sets the edge of the clock signal to define the time reference point for the setup and hold time: "Positive" Rising edge, a positive voltage change. "Negative" Falling edge, a negative voltage change. "Both" Both the rising and the falling edge.
R&S®RTO Triggers Reference for Triggers Setup time Sets the minimum time before the clock edge while the data signal must stay steady above or below the data level. The setup time can be negative. In this case, the hold time is always positive. If you set a negative setup time, the hold time is adjusted by the instrument. SCPI command: TRIGger:DATatoclock:STIMe on page 474 Hold time Sets the minimum time after the clock edge while the data signal must stay steady above or below the data level.
R&S®RTO Triggers Reference for Triggers "Timeout" Defines how long the result of the state pattern condition must be true or false. "Width" Defines a time range for keeping up the true result of the state pattern condition. The range is defined in the same way as for width and interval triggers, see "Range" on page 65.
R&S®RTO Triggers Reference for Triggers Clock level Sets the voltage level for the clock signal. SCPI command: TRIGger:SPATtern:CSOurce:LEVel on page 478 Data level Sets the voltage level for the data signal. If the signal value is higher than the data level, the state is 1. Below the level, the signal state is 0.
R&S®RTO Triggers Reference for Triggers 3.3.2 Trigger Qualification By qualifying a trigger event, you can logically combine the trigger signal with the state of other digital channel signals. The instrument triggers if both of the following apply: ● The basic conditions of the trigger event definition are fulfilled. ● The logical conditions of the trigger qualification are true. The A-event and B-event in a trigger sequence can have their own trigger qualification.
R&S®RTO Triggers Reference for Triggers "Logical operator" defines the logic combination of two sources. The sources are channel 1/2 and channel 3/4 on the first step, and in the second step the logical combination resulting from the first step.
R&S®RTO Triggers Reference for Triggers 3.3.3 Noise Reject The rejection of noise by settting a hysteresis avoids unwanted trigger events caused by noise oscillation around the trigger level. You can select the hysteresis mode and value for each channel separately, or couple the trigger levels and set the same hysteresis for channels. The hysteresis of the external trigger input is an independent value, and it is not affected by level coupling.
R&S®RTO Triggers Reference for Triggers Absolute hysteresis Defines a range in absolute values around the trigger level. If the signal jitters inside this range and crosses the trigger level thereby, no trigger event occurs. SCPI command: TRIGger:LEVel:NOISe:ABSolute on page 483 Relative hysteresis Defines a range in divisions around the trigger level. If the signal jitters inside this range and crosses the trigger level thereby, no trigger event occurs.
R&S®RTO Triggers Reference for Triggers Holdoff mode Selects the method to define the holdoff condition. T *n The trigger holdoff defines when the next trigger after the current will be recognized. Thus, it affects the next trigger to occur after the current one. Holdoff helps to obtain stable triggering when the oscilloscope is triggering on undesired events. Example: You want to analyze the first pulse in a burst of several pulses.
R&S®RTO Triggers Reference for Triggers "Auto" The holdoff time is calculated automatically based on the current horizontal scale. "Auto time scaling" defines the factor the horizontal scale is multipied with. "Auto time" shows the resulting holdoff time: Auto time = Auto time scaling * Horizontal scale.
R&S®RTO Triggers Reference for Triggers Example: If the "A Trigger" tab is selected in the "Events" tab, and the trigger level for Ch1 is 70 mV, the event coupling sets the trigger levels for Ch1 in the B- and R-events also to 70 mV. SCPI command: TRIGger:ECOupling on page 456 Delay Sets the time the instrument waits after an A-event until it recognizes B-events.
R&S®RTO Triggers Reference for Triggers The pretrigger part of the waveform can help troubleshooting, for example, to find the cause of a glitch. The posttrigger part shows what follows the trigger. Trigger offset Adds a time offset to the reference point to choose the part of the waveform to be captured and shown in the diagram. Thus, you can set the trigger outside the diagram and analyze the signal some time before or after the trigger.
R&S®RTO Triggers Reference for Triggers Hysteresis transparency Defines the transparency of the hysteresis area above or below the trigger level. The hysteresis is only visible if "Show trigger lines permanently" is enabled. 3.3.6 Control The settings and functions of trigger control define when the instrument triggers. They affect all kinds of trigger events and all triggers in a trigger sequence.
R&S®RTO Triggers Reference for Triggers "Normal" The instrument acquires a waveform only if a trigger occurs, that is, if all trigger conditions are fulfilled. If no trigger occurs, no waveform is acquired and the last acquired waveform is displayed. If no waveform was captured before, none is displayed. When no trigger has been found for longer than one second, a message box appears that shows the time elapsed since the last trigger.
R&S®RTO Triggers Reference for Triggers RUN CONT. / RUN N×SINGLE Front panel keys to start and stop a continuous acquisition or a defined number of acquisition cycles, respectively. The number of acquisitions is set with "Average count". SCPI command: RUN on page 428 SINGle on page 428 STOP on page 428 Trigger out signal setup Defines the pulse that is provided to the EXT TRIGGER OUT connector on the rear panel when a trigger occurs. To generate the trigger out signal, select "Enable trigger out".

R&S®RTO Remote Control Basics 16 Remote Control 16.1 Basics This chapter provides basic information on operating an instrument via remote control. 16.1.1 Remote Control Interfaces and Protocols The instrument supports different interfaces for remote control. The following table gives an overview. Table 16-1: Remote control interfaces and protocols Interface Protocols, VISA address string Remarks Local Area Network (LAN) Protocol: VXI-11 The LAN connector is located on rear panel of the instrument.
R&S®RTO Remote Control Basics The I/O channel (LAN or TCP/IP, USB, GPIB,...) is selected at initialization time by means of the channel–specific address string ("VISA resource string") indicated in table 16-1, or by an appropriately defined VISA alias (short name). A VISA installation is a prerequisite for remote control of R&S RTO. For more information about VISA refer to the VISA user documentation. 16.1.1.
R&S®RTO Remote Control Basics The TCP/IP network protocol and the associated network services are preconfigured. TCP/IP ensures connection-oriented communication, where the order of the exchanged messages is adhered to and interrupted links are identified. With this protocol, messages cannot be lost. 16.1.1.3 GPIB Interface (IEC/IEEE Bus Interface) To be able to control the instrument via the GPIB bus, the instrument and the controller must be linked by a GPIB bus cable.
R&S®RTO Remote Control Basics 16.1.2.2 Using the display during remote control You can observe the screen while a remote control script is executed. This is helpful for program test purposes but tends to slow down the measurement. Therefore it is recommended that you switch off the display in real measurement applications where a tested program script is to be executed repeatedly. ► To switch on the display, tap the "View" button in the upper left corner of the touch screen.
R&S®RTO Remote Control Basics – Common commands: their function and syntax are precisely defined in standard IEEE 488.2. They are employed identically on all instruments (if implemented). They refer to functions such as management of the standardized status registers, reset and self test. – Instrument control commands refer to functions depending on the features of the instrument such as frequency settings. Many of these commands have also been standardized by the SCPI committee.
R&S®RTO Remote Control Basics Command Effect on the instrument LLO (Local Lockout) The LOC/IEC ADDR key is disabled. SPE (Serial Poll Enable) Ready for serial poll. SPD (Serial Poll Disable) End of serial poll. PPU (Parallel Poll Unconfigure) End of the parallel-poll state.
R&S®RTO Remote Control Basics Command Long term Effect on the instrument &NREN Not Remote Enable Enables switchover from remote control to manual operation by means of the front panel keys &POL Serial Poll Starts a serial poll. 16.1.4 SCPI Command Structure SCPI commands consist of a so-called header and, in most cases, one or more parameters. The header and the parameters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank).
R&S®RTO Remote Control Basics 16.1.4.2 Syntax for Device-Specific Commands Not all commands used in the following examples are necessarily implemented in the instrument. For demonstration purposes only, assume the existence of the following commands for this section: ● DISPlay[:WINDow<1...
R&S®RTO Remote Control Basics Example: Definition: HCOPy:PAGE:DIMensions:QUADrant[] Command: HCOP:PAGE:DIM:QUAD2 This command refers to the quadrant 2. Different numbering in remote control For remote control, the suffix may differ from the number of the corresponding selection used in manual operation. SCPI prescribes that suffix counting starts with 1. Suffix 1 is the default state and used when no specific suffix is specified. Some standards define a fixed numbering, starting with 0.
R&S®RTO Remote Control Basics Special characters | Parameters A vertical stroke in parameter definitions indicates alternative possibilities in the sense of "or". The effect of the command differs, depending on which parameter is used. Example: Definition:HCOPy:PAGE:ORIentation LANDscape | PORTrait Command HCOP:PAGE:ORI LAND specifies landscape orientation Command HCOP:PAGE:ORI PORT specifies portrait orientation Mnemonics A selection of mnemonics with an identical effect exists for several commands.
R&S®RTO Remote Control Basics Numeric values Numeric values can be entered in any form, i.e. with sign, decimal point and exponent. Values exceeding the resolution of the instrument are rounded up or down. The mantissa may comprise up to 255 characters, the exponent must lie inside the value range -32000 to 32000. The exponent is introduced by an "E" or "e". Entry of the exponent alone is not allowed. In the case of physical quantities, the unit can be entered.
R&S®RTO Remote Control Basics INFinity, Negative INFinity (NINF) represent the numeric values 9.9E37 or -9.9E37, respectively. INF and NINF are only sent as instrument responses. ● NAN Not A Number (NAN) represents the value 9.91E37. NAN is only sent as a instrument response. This value is not defined. Possible causes are the division of zero by zero, the subtraction of infinite from infinite and the representation of missing values.
R&S®RTO Remote Control Basics Example: HCOP:ITEM:LABel "Test1" or HCOP:ITEM:LABel 'Test1' Block data Block data is a format which is suitable for the transmission of large amounts of data. A command using a block data parameter has the following structure: Example: FORMat:READings:DATA #45168xxxxxxxx The ASCII character # introduces the data block. The next number indicates how many of the following digits describe the length of the data block.
R&S®RTO Remote Control Basics ● a with EOI ● an EOI together with the last data byte Several commands in a command line must be separated by a semicolon ";". If the next command belongs to a different command system, the semicolon is followed by a colon. Example: MMEM:COPY "Test1","MeasurementXY";:HCOP:ITEM ALL This command line contains two commands. The first command belongs to the MMEM system, the second command belongs to the HCOP system.
R&S®RTO Remote Control Basics Example: Setting command: HCOPy:DEV:COL ON Query: HCOPy:DEV:COL? Response: 1 ● Text (character data) is returned in a short form. Example: Setting command: HCOPy:PAGE:ORIentation LANDscape Query: HCOP:PAGE:ORI? Response: LAND 16.1.5 Command Sequence and Synchronization IEEE 488.2 defines a distinction between overlapped and sequential commands: ● A sequential command is one which finishes executing before the next command starts executing.
R&S®RTO Remote Control Basics Example: Overlapping command with *OPC The instrument implements SINGle as an overlapped command. Assuming that SINGle takes longer to execute than *OPC, sending the following command sequence results in initiating a sweep and, after some time, setting the OPC bit in the ESR: SINGle; *OPC.
R&S®RTO Remote Control Basics 4. Wait for a service request The service request indicates that the overlapped command has finished. *OPC? with a service request 1. Set bit no. 4 in the SRE: *SRE 16 to enable MAV service request. 2. Send the overlapped command with *OPC? 3. Wait for a service request The service request indicates that the overlapped command has finished. Event Status Register (ESE) 1. Set the OPC mask bit (bit no. 0) in the ESE: *ESE 1 2.
R&S®RTO Remote Control Basics 16.1.6.1 Structure of a SCPI Status Register Each standard SCPI register consists of 5 parts. Each part has a width of 16 bits and has different functions. The individual bits are independent of each other, i.e. each hardware status is assigned a bit number which is valid for all five parts. Bit 15 (the most significant bit) is set to zero for all parts. Thus the contents of the register parts can be processed by the controller as positive integers. Fig.
R&S®RTO Remote Control Basics This part can be written into and read as required. Its contents are not affected by reading. ● EVENt The EVENt part indicates whether an event has occurred since the last reading, it is the "memory" of the condition part. It only indicates events passed on by the transition filters. It is permanently updated by the instrument. This part can only be read by the user. Reading the register clears it. This part is often equated with the entire register.
R&S®RTO Remote Control Basics Fig. 16-2: Overview of the status registers hierarchy ● STB, SRE The STatus Byte (STB) register and its associated mask register Service Request Enable (SRE) form the highest level of the status reporting system. The STB provides a rough overview of the instrument status, collecting the information of the lower-level registers.
R&S®RTO Remote Control Basics The IST flag ("Individual STatus"), like the SRQ, combines the entire instrument status in a single bit. The PPE fulfills the same function for the IST flag as the SRE for the service request. ● Output buffer The output buffer contains the messages the instrument returns to the controller. It is not part of the status reporting system but determines the value of the MAV bit in the STB and thus is represented in the overview.
R&S®RTO Remote Control Basics Bit No. Meaning 4 MAV bit (message available) The bit is set if a message is available in the output buffer which can be read. This bit can be used to enable data to be automatically read from the instrument to the controller. 5 ESB bit Sum bit of the event status register. It is set if one of the bits in the event status register is set and enabled in the event status enable register.
R&S®RTO Remote Control Basics Bit No. Meaning 3 Device-dependent Error This bit is set if a device-dependent error occurs. An error message with a number between -300 and -399 or a positive error number, which denotes the error in greater detail, is entered into the error queue. 4 Execution Error This bit is set if a received command is syntactically correct but cannot be performed for other reasons.
R&S®RTO Remote Control Basics Fig. 16-3: Overview of the STATus:QUEStionable register Table 16-6: Bits in the STATus:QUEStionable register Bit No. Meaning 0 to 2 not used 3 COVerload This bit is set if a questionable channel overload occurs (see "STATus:QUEStionable:COVerload register" on page 413). 4 TEMPerature This bit is set if a questionable temperature occurs (see "STATus:QUEStionable:TEMPerature register" on page 413). 5 to 7 Not used User Manual 1316.0827.
R&S®RTO Remote Control Basics Bit No. Meaning 8 NOALigndata This bit is set if no alignment data is available - the instrument is uncalibrated. 9 LIMit This bit is set if a limit value is violated (see "STATus:QUEStionable:LIMit, STATus:QUEStionable:MARGin, STATus:QUEStionable:LAMP registers" on page 413). 10 MARGin This bit is set if a margin value is violated (see "STATus:QUEStionable:LIMit, STATus:QUEStionable:MARGin, STATus:QUEStionable:LAMP registers" on page 413).
R&S®RTO Remote Control Basics or additional measurement of assigned measurement are violated. The LAMP (Low AMPlitude) bit is set if the magnitude of the signal is too low to get reliable measurement results. Table 16-9: Bits in the STATus:QUEStionable:LIMit, STATus:QUEStionable.MARGin, and STATus:QUEStionable:AMP registers Bit No.
R&S®RTO Remote Control Basics ● Query of a specific instrument status by means of commands ● Query of the error queue Service Request Under certain circumstances, the instrument can send a service request (SRQ) to the controller. Usually this service request initiates an interrupt at the controller, to which the control program can react appropriately. As evident from figure 16-2, an SRQ is always initiated if one or several of bits 2, 3, 4, 5 or 7 of the status byte are set and enabled in the SRE.
R&S®RTO Remote Control Basics Query of an instrument status Each part of any status register can be read using queries. There are two types of commands: ● The common commands *ESR?, *IDN?, *IST?, *STB? query the higher-level registers. ● The commands of the STATus system query the SCPI registers (STATus:QUEStionable...) The returned value is always a decimal number that represents the bit pattern of the queried register. This number is evaluated by the controller program.
R&S®RTO Remote Control Basics SYSTem:PRESet, influence the functional instrument settings. In particular, DCL does not change the instrument settings.
R&S®RTO Remote Control Command Reference Reacting to malfunctions The service request is the only possibility for the instrument to become active on its own. Each controller program should instruct the instrument to initiate a service request in case of malfunction. The program should react appropriately to the service request.
R&S®RTO Remote Control Command Reference 16.2.2.1 Waveform Suffix The numeric waveform suffix is used in REFLevel commands to indicate the source waveform number from which the reference level is taken, and to assign color tables to waveforms. Depending on the command, not all suffix values are supported. For example, in REFLevel commands, only suffixes 2...21 are allowed. The range of supported suffix numbers ist indicated in the description of the individual commands.
R&S®RTO Remote Control Command Reference Depending on the command, not all parameter values are allowed for usage: ● SEARch, EXPort commands, XY-diagram: Only analog channel waveforms (CxWy), math (Mx) and reference waveforms (Rx) are allowed. ● Sources for serial buses: Only waveform 1 of analog channels (CxW1), math (Mx) and reference waveforms (Rx) are allowed.
R&S®RTO Remote Control Command Reference 16.2.2.5 Polarity Description POSitive Positive going pulses. NEGative Negative going pulses. EITHer Both positive and negative going pulses. Event Parameter The event parameter is used with commands defining an action for mask testing, limit checks and margin checks. Event Description NOACtion The action is not initiated.
R&S®RTO Remote Control Command Reference Usually, address and identifier parameter require unique patterns while data paramters may contain wildcards. Query for a pattern The pattern format for the return value of a pattern is defined by the FORMat: BPATtern command. 16.2.3 Common Commands Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These commands have the same effect and are employed in the same way on different devices.
R&S®RTO Remote Control Command Reference Usage: Setting only *ESE Event Status Enable Sets the event status enable register to the specified value. The query returns the contents of the event status enable register in decimal form. Parameters: Range: 0 to 255 *ESR? Event Status Read Returns the contents of the event status register in decimal form and subsequently sets the register to zero.
R&S®RTO Remote Control Command Reference Sets bit 0 in the event status register when all preceding commands have been executed. This bit can be used to initiate a service request. The query form writes a "1" into the output buffer as soon as all preceding commands have been executed. This is used for command synchronization. *OPT? OPTion identification query Queries the options included in the instrument. For a list of all available options and their description refer to the CD-ROM.
R&S®RTO Remote Control Command Reference Parameters: 0|1 0 The contents of the status registers are preserved. 1 Resets the status registers. *RCL ReCaLl calls up the instrument settings from an intermediate memory identified by the specified number. The instrument settings can be stored to this memory using the command *SAV with the associated number. It also activates the instrument settings which are stored in a file and loaded using MMEMory:LOAD:STATe.
R&S®RTO Remote Control Command Reference Usage: Query only *TRG TRiGger Triggers all actions waiting for a trigger event. In particular, *TRG generates a manual trigger signal (Manual Trigger). This common command complements the commands of the TRIGger subsystem. Usage: Event *TST? self TeST query Triggers selftests of the instrument and returns an error code in decimal form (see Service Manual supplied with the instrument). "0" indicates no errors occured.
R&S®RTO Remote Control Command Reference Parameters: ASCii | REAL ASCii Data values are returned in ASCII format. REAL Binary data values are written to a file. *RST: ASCii The length is 0 for ASCII format, and 32 if Format = REAL.
