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.
