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 7
explains how to read specific register bits and use the information they return.
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
Examples
STAT:PRES STATUS:PRESET
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?

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.
CV2 = Output 2 is operating in constant voltage mode. (Agilent 66319B/D only)
CC+ = The dc source is operating in constant current mode.
CC- = The dc source is operating in negative constant current mode.
CC2 = Output 2 is operating in constant current mode. (Agilent 66319B/D only)
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)
