Switching between measurement methods
The measurement methods that are available to you depend on how you are controlling the
instrument.
If you are using the front panel to control the instrument, you can choose any of the measurement
methods.
If you are using a remote interface to control the instrument, you can only use the trigger model
measurement method. When you switch to a remote interface, the trigger model measurement
method is automatically selected. If you switch from remote control to front-panel control, the trigger
model measurement method remains selected.
If you are running a script, the instrument automatically switches to the trigger model measurement
method.
Using the front panel:
1. Press the front-panel TRIGGER key for 2 s. A dialog box displays the available trigger methods.
The presently selected method is highlighted.
2. Select the method you want to use.
3. If the instrument is in remote control, the instrument displays a confirmation dialog box. Select
Yes to change to local control.
Triggering
Triggering allows you to start and synchronize measure actions on one or more instruments with a
trigger event or a combination of trigger events that you set. This section describes some of the
options available for triggering, including command interface triggering, timers, analog trigger, and
event blenders.
Command interface triggering
A command interface trigger event occurs when:
• A GPIB GET command is detected (GPIB only)
• A VXI-11 device_trigger method is invoked (VXI-11 only)
• A *TRG message is received
To use a command interface trigger event as an input stimulus for another trigger object, set the
stimulus as TSP event trigger.EVENT_COMMAND or the SCPI event COMMAND. To ensure that
trigger commands that are issued over the command interface are processed in the correct order, the
instrument does not generate a trigger event until:
• The trigger command is executed
• TSP only: trigger.wait() retrieves the trigger command from the command queue before it
would normally be executed
