Hello, Does anyone have any experience in fixing MV89A's that have oven oscillation after warm-up (current consumption fluctuate with a 0.8-0.9 sec period from almost zero to approx 0.7A)?
While cold, OCXO drawing about 0.96A and there is no fluctuations. During warm-up current drops, and somewhere around 0.55A it started to oscillate. Amplitude of oscillation is rising slowly, and in a minute or two reaches maximum. Purchased three OCXO from ggg*fitting few months ago. As always, good working condition was promised. Two of three had really good external appearance, third was dropped, one of corners was bent. Just got time to test - all three were defective (broken output bypass cap). One in addition have lots of spurs in output spectrum, and another have oscillating oven. -- Sincerely, Yuri mailto:[email protected] _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
