Here is a brief code example written in Python 3.4 that uses a socket to pull a display image (screenshot) from a SIGLENT SDS1000X-E scope via LAN and save it to the local drive of the controlling computer.
NOTE: This program saves the picture/display image file in the same directory that the .py file is being run from. It will overwrite any existing file that has the same name.
Download Python 3.4, connect a scope to the LAN using an Ethernet cable, get the scope IP address, and run the attached .PY program to save a bitmap (BMP) image of the oscilloscope display.
You can download the .PY file here: Python_Socket_SDS_SCDP.zip
