(Uploaded and intended for myself) This little script sweeps both a Yokogawa Voltage source and a VNA in CW mode, most setting on the VNA still have to be set by hand first. (This is more of a quick and dirty measurement) The data is then stored into an *.mtx file format (1st 2 lines is the header (sizes, limits e.t.c), rest of the file is a 3d numpy data array in binary). This file can then be quickly opened with a program called 'spyview'
