Sequence 1: TRANsient settings

The sequence 1 group can synchronize the output changes using triggers. Tutorial

If ABOR is sent or if the voltage (VOLT/VOLT:OFFS) or frequency (FREQ) setting is changed, the values to which the target voltage and frequency are to change using a trigger are cancelled.

Table 5 shows the responses when the AC voltage is set to 50 V (VOLT 50) and when the target value to which the AC voltage is to change using a trigger is set to 60 V (VOLT:TRIG 60).

 

Table 5    Responses after sending VOLT 50 and VOLT:TRIG 60

  Response
VOLT? VOLT:TRIG?
Immediately after the setting 50 60
After a trigger is sent 60 60
After *RST is sent 0 0
ABOR is sent before sending a trigger 50 50 (cancel)
Voltage change VOLT 70 is sent before sending a trigger 70 70 (cancel)

 

TRIG:SOUR
