Chapter 3 Remote control
The power supply supports communication with computer through USB and LAN interface
on the rear panel.
SCPI (Standard Commands for Programmable Instruments) is an ASCII-based
programming language, which can be used to control the power supply remotely. The
computer will require Easy Power software or NI (Measurement & Automation).
In this chapter, we mainly introduce and illustrate the SCPI support
3.1 Syntax Conventions
Most commands are a mixture of upper- case and lower-case letters. The upper-case letters
indicate the command's abbreviated spelling, which yields shorter program lines. For better
program readability, use the long form. For example:
For the keyword VOLTage, you can type VOLT or VOLTage in any combination of upper- or
lower-case letters. Therefore, VolTaGe, volt and Volt are all acceptable. Other forms, such
as VOL and VOLTAG, will generate an error.
Braces ( { } ) enclose the parameter choices. The braces are not sent with the command
string.
A vertical bar ( | ) separates parameter choices. For example, {CH1|CH2} in the above
command indicates that you can specify a channel. The bar is not sent with the
command string.
Angle brackets ( < > ) indicate that you must specify a value for the enclosed parameter.
For example, the above syntax statement shows the <voltage> parameter in angle
brackets. You must specify a value for the parameter (for example " CH1:VOLT 10").
The angle brackets are not sent with the command string.
Optional parameters are enclosed in square brackets ( [ ] ). If you do not specify a value
for an optional parameter, the instrument uses a default value. For example, {CH1|CH2}
in the above command can be omitted (for example, "VOLT 10"). In this case, the
command would work on the current channel. The brackets are not sent with the
command string.
[{CH1|CH2}:]VOLTage <voltage>
