and Detecting the Completion of a
Measurement(End of Sweeps)
The state transition after the completion of each sweep varies depending on the sweep
count setting.
Once Transitions to the “Idle” state (a in Figure 5-1).
Specified number
of times Repeats a transition to the “Waiting for Trigger” state until the
specified number of sweeps are completed (b in Figure 5-1).
After the completion of the specified number of sweeps, there is a
transition to the “Idle” state (a in
Figure 5-1).
Continuous Repeats a transition to the trigger wait state (b in Figure 5-1).
Triggering a measurement
To make measurements continuously (to automatically generate triggers
continuously)
Step 1. Use the “TRGS” command to set the trigger source to the internal trigger.
Step 2. Use the “CONT” command to set the sweep setting to continuous sweep.
To make a measurement at any desired time (to generate a trigger from an external
controller)
Step 1. Use the “TRGS” command to set the trigger source to the internal trigger.
Step 2. Use the “SING” or “NUMG” command to execute a single sweep or the specified number
of sweeps at any desired time.
Or
Step 1. Use the “TRGS” command to set the trigger source to the GPIB/LAN trigger.
Step 2. Use the “CONT” command to set the sweep setting to continuous sweep.
Step 3. Execute the “*TRG” command on page 261 or the HP BASIC TRIGGER command
(execute the group execution trigger) at any desired time.
NOTE You can use the group execution trigger (GET) when you want to simultaneously trigger
all devices connected to the controller that can be triggered.
Trigger source setting Method of generating a trigger
Internal trigger (INT) Automatically generates an internal trigger.
External trigger (EXT) Enters a trigger signal from the EXT TRIGGER
terminal on the rear panel to generate a trigger.
GPIB/LAN trigger (BUS) Executes the “*TRG” command on page 261 or the
HP BASIC TRIGGER command to generate a trigger.
Manual trigger (MAN) Uses the following key sequence on the front panel to
generate a trigger:
[Trigger] - SOURCE[ ] - MANUAL
