3 Operating the DC Power Analyzer Symbol/Field: Description: 5 Scope/Arb Status Indicates whether the scope is Running, Stopped, or Waiting for a trigger. 6 Trigger Mode Indicates the trigger mode (Auto, Single, or Triggered). Sample Rate The indicated scope sample rate is based on the horizontal time/div. setting. When the time/div. setting is less than 20 ms/division, the scope will sample at its fastest rate: 20.48 microseconds.
Operating the DC Power Analyzer 3 Marker View 1 5 2 6 3 7 8 4 Symbol/Field: Description: 1 m1/m2 points Shows where the measurement markers intersect the selected waveform. Data values at the bottom of the display are referenced to the intersect locations of the markers. Calculations are based on the data points in between the intersect locations. 2 Delta Indicates the delta between the markers in units (volts, amps, or watts) and in time (seconds).
3 Operating the DC Power Analyzer Using the Waveform Display Knobs Knob: Description: Vertical Volts/Div Makes the waveform bigger or smaller vertically in relation to its ground reference. Specified in volts/division or amps/division on the y axis. If the vertical gain causes the trace to be out of view, arrow symbols will indicate the direction of the trace. Vertical Offset Moves the ground reference of the trace up or down in relation to the horizontal center line of the grid.
Operating the DC Power Analyzer 3 Scope Properties With the Scope View displayed, press the Properties key. In the Display Trace area, select which traces you wish to display. If no box is checked, no traces will be displayed for that output. NOTE Voltage, current, and power traces can be displayed simultaneously on Agilent N676xA Power Modules. All other power modules can display only voltage or current traces, but not simultaneously. Use the Trigger Mode dropdown list to select a trigger mode.
3 Operating the DC Power Analyzer If a trigger source is grayed out, it is unavailable. This can happen on power modules that cannot simultaneously display voltage and current. For these power modules, if one of the traces has been turned on, you cannot use the other trace as the trigger source. Also, current levels are not available as trigger sources on outputs that have been grouped (paralleled). Note that a trace does not have to be enabled on the displayturned on for it to be used as a trigger source.
Operating the DC Power Analyzer 3 Data Logger View NOTE The Data Logger function is not available if Option 055 has been ordered. Press the Data Logger key to access the Data Logger. This key toggles between the Standard view shown below, and Marker view, which enables markers and marker calculations. The Data Logger is similar to the Scope View function except that it lets you view and log output voltage and current data for up to 99,999 hours.
3 Operating the DC Power Analyzer Symbol/Field: Description: 4 Trigger Point Indicates the trigger position in the data log. In this example the trigger point was offset by 50%, and the pre trigger data and the post trigger data was logged. The time at the trigger point is always zero. 5 Time/Div. Identifies the horizontal time-base setting. This can be adjusted using the front panel Horizontal Time/Div knob.
Operating the DC Power Analyzer 3 Marker View 1 5 2 6 3 7 8 4 Symbol/Field: Description: 1 m1/m2 points Shows where the measurement markers intersect the selected waveform. Data values at the bottom of the display are referenced to the intersect locations of the markers. Calculations are based on the data points in between the intersect locations. 2 Delta Indicates the delta between the markers in units (volts, amps, or watts) and in time (seconds).
3 Operating the DC Power Analyzer Using the Waveform Display Knobs Knob: Description: Vertical Volts/Div Makes the waveform bigger or smaller vertically in relation to its ground reference. Specified in volts/division or amps/division on the y axis. If the vertical gain causes the trace to be out of view, arrow symbols will indicate the direction of the trace. Vertical Offset Moves the ground reference of the trace up or down in relation to the horizontal center line of the grid.
Operating the DC Power Analyzer 3 Summary View To access the Summary View, press the Menu key. Scroll down and select Arb, then select Summary View. The Summary view displays the internal filename where the data is being saved, the working directory, the time interval between data samples, and the total duration of the data log session. The Summary View also displays the average, minimum, and maximum voltage and current values of the data traces.
3 Operating the DC Power Analyzer The Duration fields let you specify the duration of the data log in hours, minutes, and seconds. The maximum duration is 99,999 hours. The Sample period specifies the interval between data samples in milliseconds, which can be set from 1 millisecond to 60 seconds. Check Log Min/Max to log the minimum and maximum values to the data log file when in Continuously-sampled mode. When Log Min/Max is checked, it will triple the resulting file size.
Operating the DC Power Analyzer 3 If a trigger source is grayed out, it is unavailable. For example, current levels are not available as trigger sources on outputs that have been grouped (paralleled). Note also that a trace must be turned on for it to be used as a trigger source. This differs from the way that current and voltage level trigger sources are selected in Scope View. The Level field lets you specify a trigger level if you selected a Voltage level or Current level as the trigger source.
3 Operating the DC Power Analyzer Markers Select the Markers button to configure the measurements that appear on the bottom of the display in Marker view. Measurements apply to the portion of the trace between the two markers. Preset Select the Preset button to return the Data Logger View to the factory-shipped display settings. As shipped from the factory, the vertical offset of each trace is set to a different value. This is to prevent the traces from overlapping.
Operating the DC Power Analyzer Data point Sample rate = 50 kHz Max. value (V or I) 3 Average value (V or I) Min. value (V or I) Sample period Sample period (Min. = 1 ms; Max. = 60 s) Standard (interleaved) Standard (interleaved) mode only applies when both voltage and current measurement traces are selected on power modules other than Agilent N676xA. These other power modules cannot measure voltage and current simultaneously; hence, the voltage and current measurements must be interleaved.
3 Operating the DC Power Analyzer Scope and Data Logger Display Differences The Scope View and Data Logger displays are similar in many respects, such as the way traces are displayed, how traces are selected, and the marker controls - to name a few. This similarity makes it easier to program each function. However, there are important differences in the Scope and Data Logger displays that may not be obvious at first glance.

Negative polarity must be programmed for all pins in this case.
Using the System Utilities 4 Trigger Out Any of the Digital Control pins can be programmed to function as a trigger output. All pins are referenced to the Signal Common pin. When configured as a trigger output, the designated trigger pin will generate a 10-microsecond trigger pulse in response to a trigger event. The polarity setting can be either positive-going (rising edge) or negative-going (falling edge) when referenced to common.
Agilent N6705A DC Power Analyzer User’s Guide 5 Operation and Connections Tutorial Operating Modes............................................................................................... 98 Wire Size ..........................................................................................................100 Multiple Loads .................................................................................................101 4-Wire Sense Considerations ..................................................
5 Operation and Connections Tutorial Operating Modes The DC Power Analyzer can operate in either constant voltage (CV) or constant current (CC) over the rated output voltage and current. Constant voltage mode is defined as an operating mode in which the dc source maintains its output voltage at the programmed voltage setting in spite of changes in load, line, or temperature.
Operation and Connections Tutorial 5 You can specify if the Start of the delay is initiated only by a settings change in voltage, current, or output state, or by any transition such as an output load change that causes the unit to cross into CC mode. Factors that influence how long the settings change or output load change may last include: difference between old output value and new output value, current or voltage limit, and output load capacitance (in CV mode) or output inductance (in CC mode).
5 Operation and Connections Tutorial Wire Size WARNING FIRE HAZARD Select a wire size large enough to carry short-circuit current without overheating. To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short-circuit output current of the unit (refer to the following table). Along with conductor temperature, you must also consider voltage drop when selecting wire sizes.
Operation and Connections Tutorial 5 Multiple Loads If you are using local sensing and are connecting multiple loads to one output, connect each load to the output terminals using separate connecting wires as shown in the following figure. 2 1. Twist leads 2. 4-wire disabled (indicator is off) 1 + + This minimizes mutual coupling effects and takes full advantage of the DC Power Analyzer's low output impedance.
5 Operation and Connections Tutorial The sense leads carry only a few milliamperes of current and can be a lighter gauge than the load leads. However, note that any voltage drop in the sense leads can degrade the voltage regulation of the instrument. Try to keep the sense lead resistance less than about 0.5Ω per lead (this requires 20 AWG or heavier for a 50 foot length). 2 1. Twist leads 2. 4-wire enabled (indicator is on) 1 + Open Sense Leads The sense leads are part of the output's feedback path.
Operation and Connections Tutorial 5 Parallel Connections CAUTION Only connect outputs that have identical voltage and current ratings in parallel. Connecting outputs in parallel provides a greater current capability than can be obtained from a single output. The following figures show how to connect two outputs in parallel. The figure on the left illustrates local sensing.
5 Operation and Connections Tutorial Voltage All parallel specifications referring to voltage are the same as for a single output except for CV load effect, CV load cross regulation, CV source effect, and CV short term drift. These are all twice the voltage programming accuracy (including the percentage portion) at all operating points. Load Transient Load transient specifications are typically twice the single output.
Operation and Connections Tutorial 5 Setting the Outputs To program outputs connected in series, first program the current limit of each output to the total desired current limit point. Then program the voltage of each output so that the sum of both voltages equals the total desired operating voltage. The simplest way to accomplish this is to program each output to one half of the total desired operating voltage.
5 Operation and Connections Tutorial Additional Load Considerations Response Time with an External Capacitor When programming with an external capacitor, voltage response time may be longer than that specified in Appendix A.
Operation and Connections Tutorial 5 Measurement Considerations Dynamic Current Correction The DC Power Analyzer measures the output current across an internal current monitor. This current monitor is located on the positive output rail on the inboard side of the output capacitor (see figure). This current measurement scheme is used by the majority of power supplies on the market today.
5 Operation and Connections Tutorial Measurement System Bandwidth NOTE The following discussion only applies when making dynamic voltage or current measurements; not when making static (or DC) measurements. The measurement bandwidth of the DC Power Analyzer is dependent on the following factors: Whether the power module that is making the measurement has an anti-aliasing filter Whether voltage or current is being measured.
