B.2 ABORt COMMAND
ABOR
Syntax: Short Form: ABOR Long Form: ABORt
Description: Cancels previously stored trigger levels, resets WTG. The ABORt command cancels any pending
trigger levels previously stored by the CURR:TRIG or VOLT:TRIG commands. The pending level is set
equal to the corresponding immediate value. ABORt also resets the WTG (Wait TriGger) bit in the
Operation Condition status register. If INIT:CONT ON has been programmed, the trigger system re-
arms itself immediately after ABORt, thereby setting WTG. WTG is bit 5 in the STATUS OPERATION
CONDITION register. The ABORt is executed each time power is turned on. Related Commands:
INIT, *RST, *TRG. (See example, Figure B-1.)
FIGURE B-1. PROGRAMMING THE OUTPUT
NOTES: 1. The power supply is assumed to be operating in constant voltage (CV) mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.3.8.1 for pro-
gramming techniques to optimize performance.
OUTP ON Output enabled.
OUTP? Power supply returns “1” (output enabled).
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.”
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 20.9V, power supply
returns 2.09E+1.
MEAS:CURR? If actual value of output current is 0.0483A, power supply
returns 4.83E-2.
FUNC:MODE? Returns VOLT if power supply operating in constant voltage
mode, CURR for constant current mode.
CURR:TRIG? Returns 3 (current value established by CURR:TRIG.
VOLT:TRIG? Returns 15 (voltage value established by VOLT:TRIG.
ABOR Pending trigger levels changed to 21V, 0.05A (immediate
values) VOLT 17; CURR 2 Power supply output programmed to
go to 17V, 2A
*TRG Power supply output returns to 21V, current limit 0.05A.
INIT:CONT 0 Triggers disabled.
INIT:CONT? Power supply returns “0.”
OUTP OFF Output disabled.
OUTP? Returns 0 (output disabled).
MEAS:VOLT? Returns 0. (measured output voltage).
VOLT? Returns 17.(programmed output voltage)/
CURR? Returns 1.5 (programmed current)
CURR? MAX Returns 4 (assuming maximum allowable current for power
supply being addressed is 4A, i.e. ABC 25-4DM).
CURR? MIN Returns 0 (minimum allowable current).
CURR:PROT 2.6 Current protection set to 2.6A.
CURR? Returns 1.5, indicating programmed current value = 1.5A.
CURR:PROT? Returns 2.6 , indicating programmed overcurrent protection
current value = 2.6A.
CURR:PROT?MAX For ABC 25-4DM, returns 4.4A (see Table 1-2).
SYST:VERS? Returns 1997.0.
