Programming mode WAVE or LIST (for Current or Voltage mode)
•
OFF Mode – No trigger output signal.
•
TRIG Mode – Trigger is generated if the LIST or WAVE sequence is completed.
•
FSTR Mode – Trigger is generated every step (after completion).
To enable Trigger Out signal functionality, refer to the Front Panel menu operation (refer to section
2.7) or to the communication command OUTPut:TTLTrg:MODE <DSC>.
6.2.4 Trigger Delay
Trigger Delay function provides the ability to delay the LIST or WAVE sequence execution following
a Trigger In. Trigger delay can be set via the Front Panel menu (refer to section 2.7) or the
communication command TRIGger:DELay <NRf+>.
To override trigger delay, use the TRIGger[:IMMediate] command. TRIGger[:IMMediate] disregards
trigger delay setting. Trigger Delay function range is 0 ~ 10 seconds, in steps of 1 mSec.

Sequencer + Trigger System Examples
A combination of the Sequencer and the Trigger System provides the ability to generate any
sequence and synchronize it.
6.3.1 WAVE Mode Voltage Programming via Communication Example
1. Select the Sequencer operation mode: VOLT:MODE:WAVE.
2. Program sequence voltage values: WAVE:VOLT 1,2,3,4.
3. Program time values corresponding to each voltage value: WAVE:TIME 1,2,3,4.
4. Store the sequence into the power supply memory cell 1: STOR 1.
6.3.2 WAVE Mode Execution via Communication Example
1. Load a sequence from the power supply memory cell 1: LOAD 1.
2. Set step parameter: WAVE:STEP AUTO.
3. Set counter parameter: COUN 1.
4. Select communication or front panel as a trigger source: TRIG:SOUR BUS.
5. Set continuous trigger initialization mode: INIT:CONT ON.
6. Initialize trigger system: INIT.
Power supply is waiting for trigger.
7. Turn on the power supply output and send a trigger command: *TRG.
NOTE
WAVE Mode execution is available via the front panel menu. Refer to PROGRAM Menu Diagram
(
Figure 2–9
).
