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
TimeR
：
0.10ms
TimeF: 0.20ms
Mode: Togg
Then press key to open the input of the load;
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 mode;
CURR 5 To set the transient current low level to 5A;
CURR:TLEVel 10 To set the transient current high level to 10A;
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 200us;
TRAN:MODE TOGG To select toggled operation mode;
INP ON To turn on the input;
INIT The initial operation before trigger
Get the trigger by receiving an external trigger signal. Figure 2-8 shows the current waveform of
the load 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 the first trigger, after 10 us duration of rising edge,
the load current reaches the high level (10A) and remains at 10A. When the second trigger is
received and after 200us duration of falling edge, the current returns to the transient low level (5A)
and remains at 5A.In toggled transient operation, the load will switch between the transient low
level and the transient high level when receiving a triggering signal and repeated the toggle in
cycle.
