Levelling up our use of the excellent TinySA Ultra spectrum analyzer with a rather nifty python/Qt app. Also putting the @MCQN_Ltd TEM cell to good use as we work on some EMI testing.

A 3D visualisation of a spectrum analyzer output for a device. The x-axis shows frequencies from low to high, with the y-axis showing the strength of the signal at each frequency. The z-axis shows how these change over time
A screenshot of the 2D visualisation of spectrum analyzer output in the QtTinySA app. There are assorted controls to set the frequency range, show markers on screen, etc. The graph again shows the frequencies across the x-axis and their strength on the y-axis - it's easier to read the specific values in this view, but harder to see how they change over time, although a coloured waterfall display below the graph does give a flavour of that.
