power supply is unregulated (the channel output mode displayed as UR). In this mode, the output
is not predictable. The unregulated condition may be caused by the fact that the AC line voltage is
below the specifications. This condition may occur temporarily. For example, when the output
voltage is programmed for a large change, the output capacitor or a large capacitive load will
charge up until the current reaches the setting value. During the ramp-up of the output voltage, the

Trigger
DP700 series power supply provides the trigger function, including trigger input and
trigger output. Trigger input indicates that the external trigger input signal controls
the on/off status of the channel output. Tr igger output indicates that controlling the
on/off status of the channel output can ena ble the in strument to output the s pecified
signal. When multiple pow er supplies are in serial or parallel connection, enabling the
external trigger function can realize the synchronous output for multiple power
supplies.
Pin 8 of the RS232 interface on the rear panel is use d for trigger input, a nd Pin 7 for
trigger output.
Pin 7: TRIG_OUT
Pin 8: TRIG_IN
Trigger is an optional function. If you want to use the trigger function, order the
option based on the O rder No. av ailable in "Appendix A: Order Information", and
then install the option by referring to "Option Configuration".
Trigger Input
Pin 8 of the RS232 interface on the rear panel is used to receive the external t rigger
input signal. When it receives a high level sig nal (≥ 2.1 V, 10 mA), the channel output
will be turned on; when it receives a low level signal (≤0.7 V, 10 mA), the channel
output will be turned off.
Operation Procedures:
1. Turn off the instrument . Connect the exte rnal trig ger in put si gnal to P in 8 of th e
RS232 interface on the rear panel.
2. Connect the load with the channel output terminals on the fr ont panel.
3. Turn on the instrument. Press System to enter the system utility interface. By
default, the "Setting" tab is selected. Press the Up/Down arrow key to switch t he

Brief Descriptions of Commands
The angle-bracket < >, brace { }, and vertical bar | are not part of the
command, and they are not sent with the commands, but taken as
delimiters to better describe the parameters in the command. When sending
the command, the parameter enclosed in the angle-bracket must contain an
effective value. The contents enclosed in the braces can contain multiple
parameter options; and the vertical bar is used to separate multiple
parameter options. When sending the comma nd, you must se lect one of the
parameters.
The letters in the commands are case-insensitive. The commands can be
input in uppercase letters or in lowercase letters. For abbreviations, you
must enter all the uppercase letters that exist in the command syntax. For
example, :SYSTem:KLOCk? MEMORY can be abbreviated as :SYST:KLOC?
MEMORY.
The contents in /*...*/ are explanations for the command.

You can remotely control the DP700 series power supply in the two following ways.
User-defined programming
Users can program and control the instrument by using the SCPI (Standard
Commands for Programm a ble Instr uments) commands. For details about the
SCPI commands and programming, refer t o
DP700 Programming Guide
Operation Procedures:
(1) Set up communication between the instrument and PC.
(2) Send commands by programming in LabVIEW, MATLAB, etc.
Use the PC software
Users can use the PC software to send commands to control the instrument
remotely. RIGOL Ultra Si gma is reco mmended. Y ou can log in to RIGOL official
website (
www.rigol.com) to download the software.
Operation Procedures:
(1) Set up communication between the instrument and PC.
(2) Run Ultra Sigma and search for the instrument resource.
(3) Open the remote command control panel to send commands.
DP700 series power supply can communicate with the PC via the RS232 interface.
This chapter will illustrate how to use the Ultra Sigma software to remotely control
the power supply via the RS232 interface.
1. Connect the power supply to the PC
Use the 9-pin RS232 cable (female-to-female, straight) to connect the power
supply to the PC through the RS232 interface on the rear panel.
.
2. Set the parameters for the RS232 interface
Press System, and then select the "Inter." tab. Set the parameters (baud rate
and parity) for the RS232 i nterface based on the set t ing descriptions in "RS232
Interface Setting".
3. Add the device resource
