For the above operating procedures, the corresponding SCPI commands should be:
MODE CCH Sets the mode
TRAN ON Enables the transient operation
CURR:LOW 1 Sets a value to low level
CURR:HIGH 5 Sets a value to high level
TRAN:HTIME 200ms Sets a value to high level time
TRAN:RTIME 10us Sets a value to time for rising edge
TRAN:FTIME 10us Sets a value to time for falling edge
TRAN:MODE PULS Selects pulsed transient operation
INPUT ON Turns on the load
.
.
Trig One trigger occurs
4.7.3 Toggled Transient Operation
Example 1: Assume that the load is in external triggering mode, set the load resistance value to periodically switch between 200 Ω and
500 Ω; set the time for rising edge (TimeR) to 10 ms; set time for falling edge (TimeF) to 10 ms; the load is in toggled transient opera-
tion, and a trigger occurs at this time.
For the above operating procedures, the corresponding SCPI commands should be:
MODE CRH Sets the mode
TRAN ON Enables the transient operation
RES:LLEV 200 Sets a value to low level
RES:HLEV 500 Sets a value to high level
TRAN:RTIME 10us Sets a value to time for rising edge
TRAN:FTIME 10us Sets a value to time for falling edge
TRAN:MODE TOGG Selects toggled operation
INPUT ON Turns on the load
.
.
Trig One trigger occurs
