Command Reference

Command

Description

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 50.

 

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 50.

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.

VLO

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

 

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

 

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

 

connected as part of the calibration procedure. Refer to this value as VLO

 

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.
