DS2202E-ScreenCapture.py is a Python script that captures whatever is displayed on the screen of a Rigol DS2202E series oscilloscope.
It can save data as a WYSIWYG (What You See Is What You Get) picture of the oscilloscope screen, or as a text file in CSV (Comma Separated Values) format.
To achieve this, SCPI (Standard Commands for Programmable Instruments) are sent from the computer to the oscilloscope, using the LXI (LAN-based eXtensions for Instrumentation) protocol over a Telnet connection. The computer and the oscilloscope are connected together by a LAN (Local Area Network). No USB (Universal Serial Bus), no VISA (Virtual Instrument Software Architecture), no IVI (Interchangeable Virtual Instrument) and no Rigol drivers are required.
