Status Operation Registers

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

Bit Configuration of Operation Registers

Bit Position 1211109876543210

Bit Name STC NU CC NU CV NU NU WTG NU NU NU NU CAL

Bit Weight 4096 2048 1024 512 256 128 64 32 16 8421

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); STC = The list step is complete;

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:OPERation[:EVENt]?

Parameters (None)

Returned Parameters <NR1> (Register Value)

Examples STAT:OPER:EVEN?

Related Commands *CLS STAT:OPER:NTR STAT:OPER:PTR

STAT:OPER:COND?

This command 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 module.

Query Syntax STATus:OPERation:CONDition?

Parameters (None)

Examples STAT:OPER:COND?

Returned Parameters <NR1> (Register value)

Related Commands (None)

STAT:OPER:ENAB

This command and its query set and read the value of the Operation Enable register. This register is a mask for enabling

specific bits from the Operation Event register to set the operation summary bit (OPER) of the Status Byte register. This bit

(bit 7) is the logical OR of all the Operation Event register bits that are enabled by the Status Operation Enable register.

Command Syntax STATus:OPERation:ENABle <NRf>

Parameters 0 to 32727

Suffix (None)

Default Value 0

Examples STAT:OPER:ENAB 1312 STAT:OPER:ENAB 1

Query Syntax STATus:OPERation:ENABle?

Returned Parameters <NRI> (Register value)

Related Commands STAT:OPER:EVEN
