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) |
Sets the condition (trigger source) for actually changing the setting value after the sequence 1 group receives INIT:SEQ1/INIT:NAME TRAN.
