INITiate[:IMMediate] COMMAND
Syntax:
Short Form: INIT:[IMM]
Description: Enables a single trigger. This command enables a single trigger. A *TRG command completes the
sequence, however TRIG:SOUR (see PAR. B.145) must be set to BUS. Upon receipt of the *TRG
command, the power supply will return to the commanded values of voltage and current established
by the VOLT:TRIG and CURR:TRIG commands. After a *TRG command has been received, subse-
quent *TRG commands have no effect unless preceded by INIT or INIT:CONT ON. Related Com-
mands: *TRG, TRIG, TRIG:SOUR. (See example, Figure B-1.)
NOTES: 1. The power supply is assumed to be operating in constant voltage mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.5.2 for pro-
gramming techniques to optimize performance.

Turns the output on.
Power supply output programmed to go to 21V, current limit 1.5A
Continuous triggers enabled.
Power supply returns "1."
Prepare unit to wait for *TRG.
Power supply output programmed to return to 15V, current limit
3A upon receipt of trigger.
Power supply output returns to 15V,current limit 3A.
Power supply output programmed to go to 21V, current limit 0.05A
If actual value of output voltage is 20.99V, power supply
returns 2.099E1 within the limits of readback accuracy.
If actual value of output current is 0.0499A, power supply
returns 4.99E-2 within the limits of readback accuracy.
Establishes constant current mode as power supply operating mode.
Power supply programmed to voltage limit 21V, 1.1A.
Returns 1.1.
Establishes constant voltage mode as power supply operating mode.
Returns 3 (current value established by CURR:TRIG).
Returns 15 (voltage value established by VOLT:TRIG).
Power supply output returns to 15V, current limit 3A.
Triggers disabled.
Power supply returns "0."
Power supply output programmed to go to 0V.
Returns 0 within the limits of readback accuracy (measured output
voltage).
Returns 0 within the limits of readback accuracy (programmed output
voltage).
Returns 3 (programmed current).
Returns 0 within the limits of readback accuracy (measured output
current)
