Trigger Source Description
Voltage <1-4> level
Current <1-4> level
Triggers the measurement when the voltageor current of the corresponding outputpasses
through the specified level.
Arb Run/Stop key Triggers the measurement when the Arb Run/Stop key is pressed.
OutputOn/Off key Triggers the measurement when any of the Output On/Off keys are pressed. Also applies to the All
Outputs On/Off key.
BNC Trigger In Provide a low-true signal to the BNC trigger input connector. Thesignal must have a minimum
pulse width of 2 microseconds. Selecting BNC Trigger In also enables any digital I/O pins con-
figured as Trigger Outputs.
Remote Command Send a trigger command over oneof 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).
Level lets you specify a trigger level if you selected a Voltage level or Current level as the trigger
source.
Slope specifies if the measurement will be triggered on the positive (up-slope) or negative (down-
slope) portion of the waveform.
Mode dropdown lets you select a trigger mode.
Trigger Mode Description
Auto Configures the scope to display a single-sweep measurement when a trigger is received, or auto-
matically if a trigger is not received. The scopecontinues running and waits for another trigger
when the measurement completes.
Single Configures the scopeto display a single-sweep measurementwhen a trigger is received. The
scope stops running when the measurement completes.
Triggered Configures the scope to display a single-sweep measurement when a trigger is received. The
scope continues running and waits for the next trigger when the measurement completes.
Scope Ranges
For outputs that have multiple measurement ranges, you can select a lower range for better
measurement resolution. Scope range settings are independent of the Meter View and Data Logger
range settings.
In the Scope Ranges area, select the desired lower measurement range from the Voltage or Current
dropdown menus.
