BOP-1K 031912 B-31FIGURE B-10. USING STATUS COMMANDS AND QUERIESB.120 STATus:questionable:ENABle? QUERY STAT:QUES:ENAB?Syntax: Short Form: STAT:QUES:ENAB? Long Form: STATus:QUESionable:ENABle?Return Value: actual register valueDescription: Reads Questionable Condition Enable Register (see Table B-4). Power supply returns value ofQuestionable 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:BEEPSyntax: Short Form: SYST:BEEP Long Form: SYSTem:BEEPDescription:Causes the unit to emit a brief audible toneNOTES: 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 forprogramming techniques to optimize performance.OUTP:ON Sets output on.STAT:PRES Operation Condition and Questionable Condition registers arereset.*CLS Resets Enable AmplifierSTAT:QUES:ENAB 12228 Allows latching of CE and VE bitsSTAT:OPER:ENAB 1280 Mask enabled for CC and CV bits.STAT:OPER:ENAB? Returns 1280 (256 + 1024) (CC and CV bits set).INIT:CONT ON Continuous triggers enabled.STAT:OPER:COND? Power supply returns 256 to indicate that powersupply is in constant voltage mode.FUNC:MODE:CURR Commands power supply to current mode.STAT:OPER? Returns 1024, indicating that since the last readingof the Operation Event Register the power supply has enteredConstant Current mode.STAT:OPER? Returns 0 indicating no changes since previous reading of theOperation Event register.STAT:QUES?
