The device supports SCPI (Standard Commands for Programmable Instruments) commands that can be used for remote control. All commands are received via the USB input (serial port).

The following parser is used to decode all incoming SCPI commands:

GitHub - j123b567/scpi-parser: Open Source SCPI device library

The following list gives an overview of the implemented (and planned) SCPI commands. It is inspired by SCPI commands summary – EEZ – Envox Experimental Zone

Try out sending one of the following commands to the device by simply opening a COM port and writing the characters. A good command for testing the connection and parser is "*IDN?" which returns some details about the device.
