4.2 Introduction to operation of front and rear panels
Before using the power supply, please understand the following basic introduction to the key
operation of front panel.
●After the power is on, the power supply shows panel operating mode automatically. Under the
panel operating mode, all keys can be used.
●When the power supply is remote operating mode, the keys on panel do not work. The panel
operating mode and remote operating mode only can be controlled for switch through PC machine.
When the operating mode changes, the output parameters of power supply will not be affected.
●You can control the output On/Off of power supply by pressing the key on the front panel.
●LED can display the current operating state of power supply. When opening the power supply,
LED will show two data, the first one shows voltage value, while the second one shows current value.

Chapter 6 SCPI Communication Protocol
6.1 Overview of SCPI command
MPS-3600LPLP series programmable DC power supply supports SCPI Communication Protocol.
SCPI is a kind of standard command used for programmable instruments, which defines a set of
command rules of communication. The command used for MPS-3600LP series power supply is
divided into two big types: basic command (IEEE-488.2 common command sets) and the command
sets designated by MPS-3600LPLP series.
SCPI commands are arranged in way of hierarchical structure of command tree. Each command
includes many alphabetic strings (mnemonic symbol), and levels are separated by colon (:). The
command on the top of command tree is called “root command” or abbreviated as “root”. One path
must be designated if visiting the next command. The structure of command tree is as follows:
In the Figure, AA means root path; BB, CC and DD are the direct sub-paths under the root path. EE,
FF and GG means the sub-paths under BB, which HH and JJ are the sub-paths under DD.
Command instruction:
1) [:] AA:CC indicates that the current root path is AA, and CC under AA will be visited.
2) [:] AA:BB:FF indicates that the current root path is AA, and FF under the sub-path BB under the

root path AA will be visited.
3) [:] AA:DD:HH indicates the current root path is AA, and HH under the sub-path DD under the root
path AA will be visited.
As for this kind of command, many commands can be sent in a message at the same time and shall be
separated with semicolon (;).
For example: [:] AA:BB:EE;FF;GG means visiting EE, FF and GG under BB.
[:] AA:BB:FF;:AA:DD:HH means visiting HH under FF and DD under BB.
The mnemonic symbols of SCPI language, namely key words, have two types including long format
and short format. Short format is actually the abbreviation of long format. The use rules are as
following:
●The mnemonic symbols of short format are made up of the first 4 alphabets of mnemonic symbol
of long format; if the alphabet length of mnemonic symbol of long format is less than or equal to 4,
then the mnemonic symbols of long format and short format are the same;
●If the length of long mnemonic symbol is larger than 4 and the fourth alphabet is vowel, the
mnemonic symbols of short format will abandon the fourth alphabet vowel and become 3 alphabets.
For example, the mnemonic symbols of short format of ERRor is ERR but not ERRO.
Some commands need parameters, such as the command of setting value. At this time, a blank is
needed between the command and its first parameter (ASCII code is 32).
For example, the command of setting voltage value is [:]VOLT 12.000
There is a blank between the parameter 12.000 and VOLT command (ASCII code is 32).
The command sets of SCPI are insensitive to the upper case and lower case, that is to say, the
commands do not distinguish upper case and lower case, and each command has an ending symbol
EOI: command ends <LF> (it indicates the character “n” of ASCII code, namely the linefeed of ASCII
code, the decimal system 10, and the hexadecimal 0A).
Notice: the ending symbol <LF> needs to be added behind all the following commands which are sent.
If square bracket [ ] appears in the following instructions, it indicates that this alphabetic string can be
written or not in the command.
6.2 Command sets of MPS-3600LP power supply
6.2.1 Basic command (IEEE-488.2 common command sets)
This command includes the general functions defined in IEEE488.2 standard, and the functions are
generally applicable to the measurement instruments which support IEEE488.2 standards. This set of
command starts with asterisk (*) and does not have hierarchical structure.

This command can read relevant information of power supply, such as the manufacturer, product
model number, product serial number, firmware version number.
6.2.2 System command
The commands stated in this section are all the commands under [:]SYSTem root path. The commands
of the following example all adopt the mnemonic symbols of short format.
Command [:]SYSTem:ERRor?
This command is used for reading the wrong code and wrong information of power supply.
Return command: wrong code, wrong information
For example: if the sending command is [:]
SYST:ERR?
<LF>
The return command of power supply is: “0, ‘No Error’ ”, or “50, ‘Error Para Count’ ”, or “70,
‘Invalid Command’ ” and other forms.

the keys on the operation front panel are invalid. Only by pressing “Shift” + “numeric key 7”, or
sending command [:]SYST:LOC, the power supply can be switched to be controlled by its front panel.
Command [:]SYSTem:LOC
This command is used for setting the power supply to be panel control model.
Return command: N/A
For example: If the power supply is under the remote control (PC) model, send command [:]
SYST:LOC
<LF>
After the command is successfully sent, the front panel of power supply has been set to be front panel
control model.
6.2.3 Measurement command

and output current value.
Return command: Numerical value list, use comma to separate them
Return parameter unit: V and A
For example: if the sending command is [:]
MEAS:VCM?
<LF>
The return command of power supply at this time is: 10.0000, 0.00000, namely, it indicates the
