Dear All,
Happy Christmas!
May I know if anyone knows the part number or the specification of the step
recovery diode in the harmonic
generator for the old HP 5601A cesium frequency standard?
I recently received this toy. The cesium tube seems to be OK, and I had
located the problem being
no 9GHz from the waveguide. I checked the diode, the DC properties seems to
be OK, but just
can not generate frequency comb any more. I really hope I can repair it as
a personal new-year gift.
I will be really appreciated, if you had any suggestions.
Best regards,
K.
