Agilent Technologies 664xA Status Subsystem, Statpres, Status Operation Registers, Statoper?

Status Subsystem

This subsystem programs the power supply status registers. The power supply has three groups of status registers; Operation, Questionable, and Standard Event. The Standard Event group is programmed with Common commands as described in "Chapter 4 - Status Reporting". The Operation and Questionable status groups each consist of the Condition, Enable, and Event registers and the NTR and PTR filters.

STAT:PRES

This command sets all defined bits in the Status Subsystem PTR registers and clears all bits in the subsystem NTR and Enable registers. STAT:OPER:PTR is set to 1313 and STAT:QUES:PTR is set to 1555.

Command Syntax	STATus:PRESet
Parameters	(None)
Examples	STAT:PRES STATUS:PRESET

Status Operation Registers

The bit configuration of all Status Operation registers is shown in the following table:

Bit Configuration of Operation Registers

Bit Position	15-12	11	10	9	8	7	6	5	4	3	2	1	0
Bit Name	NU	NU	CC	NU	CV	NU	NU	WTG	NU	NU	NU	NU	CAL
Bit Weight		2048	1024	512	256	128	64	32	16	8	4	2	1
CAL = Interface is computing new calibration constants; CC = The power module is in constant current mode.
CV = The power module is in constant voltage mode; NU = (Not used); WTG = Interface is waiting for a trigger.
Note	See "Chapter 4 - Status Reporting" for more explanation of these registers.

STAT:OPER?

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

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

STAT:OPER:COND?

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

Query Syntax	STATus:OPERation:CONDition?
Parameters	(None)
Examples	STAT:OPER:COND? STATUS:OPERATION:CONDITION?
Returned Parameters	<NR1> (Register value)
Related Commands	(None)
