Status Commands

Status commands program the dc source status registers. The dc source has three groups of status registers; Operation, Questionable, and Standard Event. The Standard Event group is programmed with Common commands as described later in this section. The Operation and Questionable status groups each consist of the Condition, Enable, and Event registers and the NTR and PTR filters. Chapter 3 under "Programming the Status Registers" explains how to read specific register bits and use the information they return.

Common commands also perform status functions. The following common commands are discussed in

this section: *CLS *ESE *SR? *OPC *PSC *SRE *STB *WAI.

STATus:PRESet

This command sets all defined bits in the Status Subsystem PTR registers and clears all bits in the subsytem NTR and Enable registers.

Command Syntax	STATus:PRESet
Parameters	None

CAL = The dc source is computing new calibration constants.

WTG = The dc source is waiting for a trigger.

CV = The dc source is operating in constant voltage mode.

CC+ = The dc source is operating in constant current mode.

CC = The dc source is operating in negative constant current mode.

STATus:OPERation?

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:OPERATIONAL:EVENT?
Related Commands	*CLS STAT:OPER:NTR STAT:OPER:PTR

STATus:OPERation:CONDition?

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 dc source .

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