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)
