Programming trigger synchronization and delays
The previous transient examples were programmed to respond to immediate triggers. However, delayed
and phase synchronized triggers can also be programmed as shown in the following examples.
No delay; no phase synchronization
VOLT:M STEP
VOLT 120
VOLT:T 150
DELAY 0
SYNC:SOUR IMM
INIT:IMMED
When these commands are sent, the voltage amplitude changes immediately
upon the receipt of a trigger.

No delay; 90 degrees phase synchronization
VOLT:M STEP
VOLT 120
VOLT:T 150
DELAY 0
SYNC:SOUR PHAS
SYNC:PHAS 90
INIT:IMMED
When these commands are sent, the voltage amplitude changes at the next
90 degree phase angle that occurs following the receipt of a trigger.
