I have found your code for controlling Nanonis quite helpful. I wonder if you can add code that controls the oscilloscope 2-channel module (starting on page 212 of Nanonis TCP manual). I have an external lock-in that plugs into one of the analog inputs of the Nanonis. After talking with SPECS, they say that the fastest way to grab data from this external lock-in is to use the oscilloscope. It would be very helpful for me if you could add this module to your library.
