Starting a measurement cycle (Triggering the instrument)
Configuring the instrument to automatically perform continuous measurement
(initial setting):
Step 1. Issue the :TRIG:SOUR command on page 310 to set the trigger source to Internal trigger.
Step 2. If the trigger system is in Idle state (that is, it is not currently active), issue the
:INIT:CONT command on page 287 to turn on continuous activation of the trigger system.
Starting measurement on demand:
1) To trigger the instrument on demand, follow the steps below.
Step 1. Issue the :TRIG:SOUR command on page 310 to set the trigger source to GPIB/LAN
trigger.
Step 2. If the trigger system is in Idle state (that is, it is not currently active), issue the
:INIT:CONT command to turn on continuous activation of the trigger system.
Step 3. Trigger the instrument whenever you want to perform measurement. An external controller
can trigger the instrument with one of the following two commands:
Step 4. To start the next measurement cycle, repeat step 3.
2) To activate the trigger system on demand, follow the steps below.
Step 1. If the trigger system is active (that is, not in Idle state), issue the :ABOR command on
page 209 to stop the trigger system.
Step 2. Issue the :TRIG:SOUR command on page 310 to set the trigger source to Internal trigger.
Step 3. You can activate the trigger system using the :INIT command on page 287 at any time.
Consequently, the instrument will be automatically triggered by Internal trigger and
perform one measurement cycle.
Step 4. To start the next measurement cycle, repeat step 3.
