Status Subsystem
This subsystem programs the power supply status registers. The power supply has two groups of status registers; Operation
and Questionable. Each group consists of the following five registers:
Condition Enable Event NTR Filter PTR Filter
Status Operation Registers
The bit configuration of all Status Operation registers is shown in the following table:
Bit Configuration of Operation Registers
Bit Position15-1211109876 5 43210
Condition NU NU CC NU CV NU NU WTG NU NU NU NU NU
Bit Weight 2048 1024 512 256 128 64 32 16 8 4 2 1
CC = Power supply is sourcing current in CC mode; CV = Power supply is in constant voltage mode; NU = (Not used);
WTG = Interface is waiting for a trigger.
See "Status Reporting" for more explanation of these registers.
STAT:OPER:COND?
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?
Examples STAT: OPER: COND? STATUS: OPERATION: CONDITION?
Returned Parameters <NRl>
(Register value)
STAT:OPER:ENAB
Sets or reads the value of the Operation Enable register. The Operation Enable register is a mask for enabling specific bits
in the Operation Event register that can cause the operation summary bit of the Status Byte register to be set. The operation
summary bit (bit 7) is the logical OR of all the enabled bits in the Operation Event register.
Command Syntax STATus:OPERation:ENABle <NRf>
Parameters 0 to 32727
Default Value 0
Examples STAT: OPER: ENAB 1312 STAT: OPER: ENAB 1 STATUS:OPERATION:ENABLE? Query
Syntax STAT:OPER:ENAB?
Returned Parameters <NRl>
(Register value)
STAT:OPER:EVEN?
Returns the value of the Operation Event register. The Event register is a read-only register
which holds (latches) all events that:
♦ are enabled by the Operation Enable register.
♦ are passed by the Operation NTR and/or PTR filter.
Reading the Operation Event register clears it.
