Baris Cakmak Posted December 30, 2019 Report Share Posted December 30, 2019 Hello,I would like to investigate QCM with dissipation monitoring by quartz crystal. Basic approach is opening and closing the function generator at crystal's resonance level. I have 10MHz crystal. By AD9851(or any dds suggestion I would accept) I am going to give 10MHz sinusoidal signal. There is no issue with that but I want to see decaying signal. To do that, At least 5ms operate time switch(maybe relay) I need it(to see decay signal in ms or ns level signal start and end dissipation). I dont want any distortion to signal to distort. What can I use as a switch for DDS? Thank you. Quote Link to comment Share on other sites More sharing options...
