R&S®Scope Rider RTH Waveform Setup Connecting Probes 3 Waveform Setup 3.1 Connecting Probes Shock hazard caused by high voltages Make sure to set the attenuation factor on the instrument according to the probe being used. Otherwise, the measurement results do not reflect the actual voltage level, and you might misjudge the actual risk. 1. Connect the probe(s) to the channel input(s) at the top of the instrument. 2.
R&S®Scope Rider RTH Waveform Setup Vertical Setup 6. Switch off the test circuit. 7. Connect the probe to the DUT. 8. Switch on the test circuit. 3.2 Vertical Setup The controls and parameters of the vertical system adjust the scale and position of the waveform vertically. 1. To set vertical scale and position, use the [RANGE] and [POS] keys. 2. To adjust other vertical settings, select "Vertical" in the main menu.
R&S®Scope Rider RTH Waveform Setup Vertical Setup 3.2.1 Vertical Settings As long as the "Vertical" menu is open, the probe settings of active channels are shown on top of the display. Channel Index Selects the channel to be configured. All settings in the channel menu belong to the selected channel. You can also shortly press the channel key to select a channel. If you press and hold the channel key, the corresponding channel menu opens. Channel Switches the selected channel on or off.
R&S®Scope Rider RTH Waveform Setup Vertical Setup AC coupling. A high-pass filter removes the DC offset voltage from the input signal if the DC component of a signal is of no interest. The waveform is centered on zero volts. If AC coupling is set, the attenuation of passive probes has no effect, and voltage is applied to the instrument with factor 1:1. Observe the voltage limits, otherwise you can damage the instrument. DC coupling, the signal passes the input unchanged.
R&S®Scope Rider RTH Waveform Setup Vertical Setup The oscilloscope is not an autonomous system. You need a probe to measure the signal, and the probe has a limited bandwidth, too. The combination of oscilloscope and probe creates a system bandwidth. To reduce the effect of the probe on the system bandwidth, the probe bandwidth should exceed the bandwidth of the oscilloscope, the recommended factor is 1.5 x oscilloscope bandwidth. See also: Chapter 3.2.2, "Effect of the Bandwidth Filter", on page 45.
R&S®Scope Rider RTH Waveform Setup Vertical Setup Remote command: CHANnel:DESKew on page 307 Technology, Value Sets the threshold, which is used to obtain the signal state. If the signal value is higher than the threshold, the signal state is high (1 or true for the Boolean logic). Otherwise, if the signal value is below the threshold, the signal state is considered low (0 or false). The threshold is used by the pattern and state trigger.
R&S®Scope Rider RTH Waveform Setup Horizontal Setup 3.2.2 Effect of the Bandwidth Filter Low-pass filters reduce the speed of the signal inside the instrument and cause a delay of the signal on the screen. The delay time depends on the selected filter. The following table lists the approximate delay of the signal that is caused by various filters. Table 3-1: Approximate signal delay dependent on the bandwidth filter Filter Approx. delay Filter Approx. delay 200 MHz 30.2 ns 500 kHz 9.
R&S®Scope Rider RTH Waveform Setup Horizontal Setup t=0 T Horiz. position from right ref. point (> 0) Horiz. position from middle ref. point (> 0) Horiz. position from left ref. point (< 0) Reference point = Left Reference point = Middle Reference point = Right Signal delay If you have set a bandwidth limit, the signal might appear delayed on the screen. The delay time depends on the selected filter. The effect is visible if several signals with different limits are displayed. See also: Chapter 3.2.
R&S®Scope Rider RTH Waveform Setup Acquisition Control You can set the trigger point even outside the diagram and analyze the signal some time before or after the trigger. In this case, the trigger marker is shown on the left or right side of the diagram. To set the horizontal position, you can also use the [POS] keys. Remote command: TIMebase:HORizontal:POSition on page 309 Reference Point Defines the time reference point in the diagram.
R&S®Scope Rider RTH Waveform Setup Acquisition Control Description of settings Figure 3-1: Acquire menu of R&S RTH1002 (without mixed signal option R&S RTH-B1) Acquisition Mode Defines how the waveform is built from the captured samples. There are two general methods to build the waveform record: sample decimation and waveform arithmetic. Sample decimation reduces the data stream of the ADC to a stream of waveform points with lower sample rate and a less precise time resolution.
R&S®Scope Rider RTH Waveform Setup Acquisition Control "Average" The average is calculated from the data of the current acquisition and several acquisitions before. The method reduces random noise. It requires a stable, triggered and periodic signal. The number of acquisitions for average calculation is defined with Number of Averages. "Envelope" The minimum and maximum values in a sample interval over several acquisitions are saved. The most extreme values of all acquisitions build the envelope.
R&S®Scope Rider RTH Waveform Setup Roll Mode ● ● In roll mode, if analog and digital channels are active: the minimum record length of analog channels or digital channels is used. At slow timebases: see Waveform Update. If the "Time Scale" is set to 100 s/div or higher, the actual record length can be higher than the value set with "Preselected Record Len." on page 49. Act. Record Len. D7 - D0 Shows the actual record length of digital channels.
R&S®Scope Rider RTH Waveform Setup Trigger To analyze the signal in roll mode, you can use: ● Zoom ● Automatic measurements ● Cursor measurements ● Mathematics You can also save the waveform data. Saving stops the acquisition. Acquisition is resumed when the data is written. 3.6 Trigger 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 signals.
R&S®Scope Rider RTH Waveform Setup Trigger ► To start and stop acquisition, press the [RUN STOP] key. 3.6.1 General Trigger Settings General trigger settings are the settings that are independent of the trigger type.

R&S®Scope Rider RTH SCPI Command Structure Syntax for Device-Specific Commands A.2.2 Numeric Suffixes If a command can be applied to multiple instances of an object, e.g. specific channels or sources, the required instances can be specified by a suffix added to the command. Numeric suffixes are indicated by angular brackets (<1...4>, , ) and are replaced by a single value in the command. Entries without a suffix are interpreted as having the suffix 1.
R&S®Scope Rider RTH SCPI Command Structure SCPI Parameters A.3 SCPI Parameters Many commands are supplemented by a parameter or a list of parameters. The parameters must be separated from the header by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank). The parameters required for each command and the allowed range of values are specified in the command description. Allowed parameters are: ● ● ● ● ● ● Numeric Values...........................................................................
R&S®Scope Rider RTH SCPI Command Structure SCPI Parameters Example: HCOP:PAGE:SCAL 90PCT A.3.2 Special Numeric Values The following mnemonics are special numeric values. In the response to a query, the numeric value is provided. ● MIN and MAX: denote the minimum and maximum value. ● DEF: denotes a preset value which has been stored in the EPROM. This value conforms to the default setting, as it is called by the *RST command. ● UP and DOWN: increases or reduces the numeric value by one step.
R&S®Scope Rider RTH SCPI Command Structure SCPI Parameters Example: Setting command: HCOPy:DEV:COL ON Query: HCOPy:DEV:COL? Response: 1 A.3.4 Text Parameters Text parameters observe the syntactic rules for mnemonics, i.e. they can be entered using a short or long form. Like any parameter, they have to be separated from the header by a white space. In the response to a query, the short form of the text is provided.
R&S®Scope Rider RTH SCPI Command Structure Overview of Syntax Elements A.4 Overview of Syntax Elements The following tables provide an overview of the syntax elements and special characters. Table A-2: Syntax elements : The colon separates the mnemonics of a command. ; The semicolon separates two commands of a command line. It does not alter the path. , The comma separates several parameters of a command. ? The question mark forms a query. * The asterisk marks a common command.

R&S®Scope Rider RTH SCPI Command Structure Responses to Queries Example: HCOP:ITEM ALL;:HCOP:IMM This command line contains two commands. Both commands are part of the HCOP command system, i.e. they have one level in common. If the successive commands belong to the same system, having one or several levels in common, the command line can be abbreviated. When abbreviating the command line, the second command begins with the level below HCOP. The colon after the semicolon is omitted.
R&S®Scope Rider RTH Command Sequence and Synchronization Preventing Overlapping Execution B Command Sequence and Synchronization IEEE 488.2 defines a distinction between overlapped (asynchronous) and sequential commands: ● A sequential command finishes executing before the next command starts executing. Commands that are processed quickly are usually implemented as sequential commands.
R&S®Scope Rider RTH Command Sequence and Synchronization Preventing Overlapping Execution Table B-1: Synchronization using *OPC, *OPC? and *WAI Command Action Programming the controller *OPC Sets the Operation Complete bit in the ESR after all previous commands have been executed. ● ● ● *OPC? Stops command processing until 1 is returned. This occurs when all pending operations are completed.
R&S®Scope Rider RTH User Scripting (R&S RTH-K38) Running User Apps C User Scripting (R&S RTH-K38) Using the scripting option R&S RTH-K38, you can run your own apps to automatize measurements or visualize specific results that are not available in the product. The option provides the interface to start the apps and an app window to show results. Apps are not included in the option. C.
R&S®Scope Rider RTH User Scripting (R&S RTH-K38) About User Apps To stop a running app ► Tap the "Close" icon in the upper right corner of the app window, or press the [BACK] key. [PRESET] also stops the app. When an app is running The instrument works as follows when an app is running: ● The app window covers a part of the measurement display. To move the window, tap left beside the "Close" icon and drag it. ● The keys and the touchscreen work as usual, they are not blocked.
