Status Questionable Registers

Status Questionable Registers

Bit Configuration of Questionable Registers

Bit Position	15-11	10	9	8	7	6	5	4	3	2	1	0
Condition	NU	UNR	RI	NU	NU	NU	NU	OT	NU	NU	OC	OV
Bit Weight		1024	512	256	128	64	32	16	8	4	2	1

NU = (Not used); OC = Overcurrent protection circuit has tripped.

OT = Overtemperature status condition exists; OV = Overvoltage protection circuit has tripped. RI = Remote inhibit is active; UNR = Power supply output is unregulated.

Note: See "Chapter 4 - Status Reporting" for more explanation of these registers.

STAT:QUES?

This query returns the value of the Questionable Event register. The Event register is a read-only register which holds (latches) all events that are passed by the Questionable NTR and/or PTR filter. Reading the Questionable Event register clears it.

Query Syntax	STATus:QUEStionable[:EVENt]?
Parameters	(None)
Returned Parameters	<NR1>	(Register Value)
Examples	STAT:QUES?	STATUS:QUESTIONABLE:EVENT?
Related Commands	*CLS STAT:QUES:ENAB STAT:QUES:NTR
	STAT:QUES:PTR

STAT:QUES:COND?

This query returns the value of the Questionable Condition register. That is a read-only register which holds the real-time (unlatched) questionable status of the power supply.

Query Syntax	STATus:QUEStionable:CONDition?
Parameters	(None)
Examples	STAT:QUES:COND? STATUS:QUESTIONABLE:CONDITION?
Returned Parameters	<NR1> (Register value)
Related Commands	(None)

STAT:QUES:ENAB

This command and its query set and read the value of the Questionable Enable register. This register is a mask for enabling specific bits from the Questionable Event register to set the questionable summary bit (QUES) of the Status Byte register. This bit (bit 3) is the logical OR of all the Questionable Event register bits that are enabled by the Questionable Status Enable register.

Command Syntax	STATus:QUEStionable:ENABle <NRf>
Parameters	0 to 32727
Suffix	(None)
Default Value	0
Examples	STAT:QUES:ENAB 20 STAT:QUES:ENAB 16
Query Syntax	STATus:QUEStionable:ENABle?
Returned Parameters	<NR1> (Register value)
Related Commands	STAT:QUES?
