These commands program the electronic load status registers. The electronic load has five
groups of status registers; Questionable Status, Standard Event Status, and Operation
Status.
Bit Configuration of Operation Status Registers
Bit Position 15 14 13 12 11 10 ~ 4 3 2 ~ 1 0
Bit Name Not used VPP VNP INF UTP Not used WTG Not used CAL
Bit Weight 0 16384 8192 4096 2048 0 32 0 1
CAL = Interface is computing new calibration constants
WTG = Interface is waiting for a trigger
UTP = Warning Message - The eLOAD is operating continuously under low temperatures (below 15 degrees
Celsius), which will cause condensation if persisted
INF = In-fault Protection – Power Stage failure condition (Critical Failure)
VNP = Voltage Negative Protection – Internal Negative Bias Voltages Failure (Critical Failure)
VPP = Voltage Positive Protection – Internal Positive Bias Voltages Failure (Critical Failure)
STATus:OPERation?
This query returns the value of the Operation Event register. The Event register is a read-only register
that holds (latches) all events that are passed by the Operation NTR and/or PTR filter. Reading the
Operation Event register clears it. This command is not channel specific, it applies to the entire
mainframe.
Query Syntax STATus:OPERation?
Parameters None
Returned Parameters (register value)
STATus:OPERation:CONDition?
This query returns the value of the Operation Condition register. That is a read-only register that holds
the real-time (unlatched) operational status of the electronic load. This command is not channel
specific, it applies to the entire mainframe.
Query Syntax STATus:OPERation:CONDition?
Parameters None
Returned Parameters (register value)
STATus:OPERation:ENABle
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. The operation summary bit is the logical OR of all enabled
Operation Event register bits. This command is not channel specific, it applies to the entire
mainframe.
Command Syntax STATus:OPERation:ENABle
Parameters 0 to 32767 | MIN | MAX
Default Value 0
Query Syntax STATus:OPERation:ENABle?
Returned Parameters (register value)
