STATUS COMMANDS

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 <NR1> (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 <NR1> (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 <NR1>

Parameters 0 to 32767 | MIN | MAX

Default Value 0

Query Syntax STATus:OPERation:ENABle?

Returned Parameters <NR1> (register value)

1 2 ... 37 38 39 40 41 42 43 44 45 46 47 ... 73 74
