I'm trying to analyze a signal I got out of a scope on my PC and a program like TekScope Anywhere looks like it will do what I'm after.
How can I get plots and data of the scope?
PyVISA will generally take care of connecting to most Tektronic Scopes, the VISA interface was originally GPIB based and early Tek TDS scope have GPIB interfaces, but the general API and command interface is still present in the USB Versions as well. Afterwards plotting with matplotlib or gnuplot if you prefer .
The somewhat Generic command
CURVE? will return the immediate sample data, but the full command suite allows you to set triggers, x/y scale, inputs , sample rate, etc. Full capabilities depends on the scope.
Here is my basic implementation from a number of years ago of digital reading utility for a Tek Scope, it is written for a GPIB backend but is directly compatible with PyVISA Backend
There's an early free version (220.127.116.11) of TekScope:
