Chapter 14 Programming Examples

This chapter displays the programming examples to remotely control IT-M7700

power supply using SCPI commands.

Note



If the user want to change the settings of the instrument, for instance, the output

setting value, the command SYST:REM must be sent to the instrument after

finishing the connection between the instrument and PC.



“

- >

”

indicates the commands that you send to the IT-M7700 power supply.



Self-defined Waveform, Dimmer, Surge/Trap and List commands is a special command of

IT-M7721/IT-M7722/IT-M7723/IT-M7723E

, but it’s not suitable

for IT-M7721L/IT-M7722L.

Example 1: Identifying the Power Supply in Use

You can verify whether you are communicating with the right IT-M7700 power

supply.

To query the identification of the power supply, send the command:

-> *IDN?

To check the power supply error queue, send the command:

-> SYST:ERR?

Example 2: Applying DC Output

The IT-M7700 is configured as a DC power supply and outputs 20V voltage.

Please enter the following command:

-> SYSTem:REMote

-> NORMal:MODE DC

-> NORMal:VOLTage:DC 20.0

-> PROTect:MAX:CURRent:LIMit 20.0

-> OUTPut ON

-> MEASure:VOLTage:DC?

-> MEASure:CURRent:DC?

-> MEASure:POWer?
