Magnus, others My previous mail was not very clear but the jumping problem was solved. It was not caused by the TCXO but by small current fluctuations in the TCXO causing small VCC fluctuations causing feedback into he Vtune input because the Vtune was derived from the VCC. I just did not realize how sensitive the Vtune input was.
Thanks again for the feedback as now I realize I need to check if there is not a synthesizer inside that is being set when changing Vtune or temperature causing unwanted clicks or steps. Can this be tested by using a slow small sweep on Vtune and check with timelab is there are no jumps in the sweep? Or is it better to analize a high harmonic of the 10MHz on a SA? _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
