There are no remote interface commands that correspond directly to the front
panel Scope functions. See chapter 5, "Digitizing Measurements" for
information on programming digitized measurements from the remote interface.
With the Scope View displayed, press the Properties key to access the
Scope Properties window.
In the Display Trace area, select which traces to display for the
output. If no box is checked, no traces will be displayed for that
output. Voltage, current, and power traces can be displayed
simultaneously only on Agilent Models N676xA and N678xA SMU, as
these models have simultaneous voltage and current measurement
capability (see chapter 1, "Power Module Features"). All other power
modules can display either voltage or current traces, but not
simultaneously.
In the Trigger area, use the Source dropdown list to select a trigger
source. This trigger source will trigger the scope measurements on all
output channels. Depending upon the selected trigger source, you can
trigger the scope as follows:
Description:
Triggers the measurement when the voltage or current of the corresponding
output passes through the specified level.
Trigger the measurement when the Arb Run/Stop key is pressed.
Trigger the measurement when any of the Output On/Off keys are pressed.
Also applies to the All Outputs On/Off key.
Provide a low-true signal to the BNC trigger input connector. The signal must
have a minimum pulse width of 2 microseconds. Selecting BNC Trigger In also
enables any digital I/O pins configured as Trigger Outputs (see Appendix C).
Send a trigger command over one of the three interfaces (i.e. *TRG).
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).
