It works OK when remembering to set frequency start and stop before doing a sweep. On the TinySA the Attennuation and reference level must be set to manual in particular for Multiple segments and if so set I got it to work just fine
For those using Linux Multiple segments is now working in tinySA-saver
The tinySA data is in the S21Gain (dB) graph. Suggest to remove all other displayed charts except S21 Gain Make sure you set the tinySA in high or low input mode before running tinySA-saver Screen capture works. See "manage"/"screenshot" Apart from making the data visible I did not do ANYTHING to make it robust
