FIGURE B-10. USING STATUS COMMANDS AND QUERIES
B.120 STATus:questionable:ENABle? QUERY
STAT:QUES:ENAB?
Syntax: Short Form: STAT:QUES:ENAB? Long Form: STATus:QUESionable:ENABle?
Return Value: actual register value
Description: Reads Questionable Condition Enable Register (see Table B-4). Power supply returns value of
Questionable Condition Enable Register, indicating which conditions are being monitored. Bit set to 1
= function enabled (active, true); bit reset to 0 = function disabled (inactive, false)
. Related Com-
mands: STAT:QUES?. (See example, Figure B-10.)
B.121 SYSTem:BEEP COMMAND
SYST:BEEP
Syntax: Short Form: SYST:BEEP Long Form: SYSTem:BEEP
Description:Causes the unit to emit a brief audible tone
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. 3.5.2 for
programming techniques to optimize performance.
OUTP:ON Sets output on.
STAT:PRES Operation Condition and Questionable Condition registers are
reset.
