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

Query Syntax (None)

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)
