Operation

Command Reference

Release 1.2 45

Command Description

STS? Asks for the supply’s present status register. Status conditions are stored in

the status register. Each bit represents a separate condition. When the

condition is true, the corresponding bit is 1 (true). Bits remain set in the

status register as long as the condition is true. See

“Accumulated Status,

Status, and Fault Registers” on page 47

Response: STS <status mask> where status mask is the decimal equivalent

of the total bit weights for the operating conditions as listed in the status

TRG Implements programmed voltage and current settings which had been in

hold mode. The supply operates with previous values until the TRG (trigger)

command is sent.

UNMASK <mnemonics> Enables you to select the supply operating conditions that you are most

interested in monitoring for fault occurrence. Mnemonics describing the

conditions are separated from each other by commas, and may be sent in

any order.

Specifying one or more mnemonics which describe the conditions (or the

decimal equivalent of their total bit weight) enables the selected conditions

to set bits in the supply’s fault and status registers during operation. A bit is

set in the fault register when the corresponding bit in the status register

changes from 0 to 1 and the corresponding bit in the mask register is 1. See

“Accumulated Status, Status, and Fault Registers” on page 47.

Mnemonics: CV, CC, OV, OT, SD, FOLD, ERR, PON, REM, ACF, OPF,

SNSP, ALL, NONE

Initial value: UNMASK NONE

UNMASK? Asks for the supply's fault conditions which are currently enabled

(unmasked).

Response: UNMASK <fault mask> where fault mask is the decimal

equivalent of the total bit weights for the operating conditions as listed in the

status and fault registers See

“Accumulated Status, Status, and Fault

Registers” on page 47.

VDATA <Vlo>,<Vhi> Calculates and records the slope and offset for programmed voltage using

VLO and VHI data. Set CMODE ON before using this command. See also

the calibration procedures in Section 4.

<Vlo> and <Vhi> are in <voltage> format.

VHI In response to this command, the power supply sends a programmed

voltage value to the output terminal. This value is at the high end of the

power supply’s voltage range and is read by an external device connected

as part of the calibration procedure. Refer to this value as VHI and record it

to use as input with the VDATA command. Set CMODE ON before using

this command. See also the calibration procedures in Section 4.
