Hello. 
I have a NanoVNA-H4, with DiSlord 1.2.40 firmware.  
I would like to write a python program to measure and sort crystals for use in a crystal filter.  Is there a way to read out the parameters via the USB connection? 
I have tried to navigate the manuals and the help menu, but have not found anything if it is possible to read it out via USB.
