[time-nuts] HP OCXO's 10544A and 10811A

[timeok at timeok.it]

   Walter,

   The two OCXO are not electrically compatible, you can connect a 10811in an equipment  wired for the 10544 but not the reverse.

   The 10811 is a SC cut crystal oscillator and the 10544 is an AT cut.

   The crystals are individually tested and the temperature is set at the best point of every single crystal .

   The 10811 is lower as Phase Noise than the 10544.

   Oggetto [time-nuts] HP OCXO's 10544A and 10811A
   I have hp counters with both OCXO's, they seem to be electrically and
   mechanically interchangeable,
   and generally, they both have performed well.
   but it seems to me that the earlier 10544A runs hotter (to the touch),
   and is not quite as long
   term stable as the 10811A. how have they worked for you?

   is there a comparison of the key characteristics of these two sub-assembles?

   all the best,
   walter
