FIGURE B-1. PROGRAMMING THE OUTPUT
B.6 INITiate:CONTinuous COMMAND
INIT:CONT
Syntax: Short Form: INIT:CONT {ON | OFF} or {1 | 0} (1 = on, 0 = off)
Long Form: INITiate:CONTinuous {ON | OFF} or {1 | 0} (1 = on, 0 = off)
Description: INIT:CONT ON enables continuous triggers.; INIT:CONT OFF disables continuous triggers. If
INIT:CONT is OFF, then INIT[:IMM] arms the trigger system for a single trigger. If INIT:CONT is ON,
then the trigger system is continuously armed and INIT[:IMM] is redundant. While INIT:CONT is ON,
WTG (bit 5 of the Operation Status Condition register (See Table B-4) is always 1 if the TRIG:SOUR is
BUS. If TRIG:SOUR is set to EXT, WTG is reset to 0 when the trigger is generated, then set to 1 auto-
matically by the unit. Unlike the BUS trigger source, the transitions in WTG status can be captured by
setting WTG (bit 5) in the Status Operation Enabled Register to cause the WTG bit to be set in the Sta-
tus Operation Event register. (See example, Figure B-1.) Executing *RST sets the init:cont state to 0
or off and clears the WTG bit in the STATUS OPERATION REGISTER.
B.7 INITiate:CONTinuous? QUERY
INIT:CONT?
Syntax: Short Form: INIT:CONT? Long Form: INITiate:CONTinuous?
Return Value: 1 or 0
Description: Determines whether continuous triggers are enabled or disabled. Power supply returns value of
INIT:CONT flag: “1” = continuous triggers are enabled (INIT:CONT ON); “0” = continuous triggers dis-
abled (INIT:CONT OFF). (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.
OUTP ON Turns the output on.
VOLT 21; CURR 1.5 Power supply output programmed to go to 21V, current limit 1.5A
INIT:CONT ON Continuous triggers enabled.
INIT:CONT? Power supply returns “1.”
TRIG:SOUR BUS Prepare unit to wait for *TRG.
VOLT:TRIG 15;CURR:TRIG 3 Power supply output programmed to return to 15V, current limit
3A upon receipt of trigger.
*TRG Power supply output returns to 15V,current limit 3A.
VOLT 21; CURR 5E-2 Power supply output programmed to go to 21V, current limit 0.05A
MEAS:VOLT? If actual value of output voltage is 20.99V, power supply
returns 2.099E1 within the limits of readback accuracy.
MEAS:CURR? If actual value of output current is 0.0499A, power supply
returns 4.99E-2 within the limits of readback accuracy.
FUNC:MODE CURR Establishes constant current mode as power supply operating mode.
VOLT 21; CURR 1.1 Power supply programmed to voltage limit 21V, 1.1A.
CURR? Returns 1.1.
FUNC:MODE VOLT Establishes constant voltage mode as power supply operating mode.
CURR:TRIG? Returns 3 (current value established by CURR:TRIG).
VOLT:TRIG? Returns 15 (voltage value established by VOLT:TRIG).
*TRG Power supply output returns to 15V, current limit 3A.
INIT:CONT 0 Triggers disabled.
INIT:CONT? Power supply returns “0.”
VOLT 0 Power supply output programmed to go to 0V.
MEAS:VOLT? Returns 0 within the limits of readback accuracy (measured output
voltage).
VOLT? Returns 0 within the limits of readback accuracy (programmed output
voltage).
CURR? Returns 3 (programmed current).
MEAS:CURR? Returns 0 within the limits of readback accuracy (measured output
current).
