do the trigger initial operation before the trigger operation, otherwise the load won’t response to
the trigger.
For example: assume that the CCH range is active, and the input of the load is OFF, then the
transient parameters should be set as follows:
Press dynamic key to enter into transient operation interface;
Set the following parameters in the transient operation menu:
LevelL: 5.000A
LevelH: 10.000A
TimeH: 0.50ms
TimeR: 0.10ms
TimeF: 0.10ms
Mode: Puls
Then press key to turn on the input;
Send the trigger initial command to the load
：
INIT;
Or set via the remote programming interface:
SCPI Command Description
TRIG:SOUR EXT To select the external trigger input;
SYSTem:STATe TRANsient To enter the transient operation;
CURR 5 To set the transient current low level to 5A;
CURR: TLEVel 10 To set the transient current high level to 10A;
TRAN:HTIM 0.0005 To set the transient high level time to 500us;
TRAN:RTIM 0.0001 To set the time for transient rising edge to 100us;
TRAN:FTIM 0.0002 To set the time for transient falling edge to 100us;
TRAN:MODE PULS To set the pulsed operation mode;
INP ON To open the input of the load;
INIT The initial operation before trigger
Get the trigger by receiving an external trigger signal. Figure 2-7 shows the current waveform of
the load in pulse transient operation before and after being triggered. After the input of the load is
ON, the load starts its operation at the transient low level (5A). For each trigger, after 10 us
duration of rising edge, the load current reaches the high level (10A) and remains at 10A for 500us.
