============================================================= Coincidentally, Battosai42 has an open-source project for automated measurement of crystal parameters using either a miniVNA or nanoVNA. The measurement method requires a passive test-fixture according to IEC-444 which is a double-pi network terminating the crystal at 12.5Ohm. The IEC-444 fixture appears to be the same one described in the pdf document uploaded by EB4APL. A beta distribution of the application is located at . I don't have the IEC-444 fixture, but I have run the beta application and verified that it talks to the NanoVNA. A screen-shot of the application is attached. Keep in mind this is an open-source program that is still under development and, therefore; you should not expect any support - although providing the author with encouraging feedback would surely be appreciated. - Herb |
