Hello, Has anyone attempted or successfully upgraded an older HP 5065A to use a new 10811 oscillator?
HP created an upgrade kit for this purpose and provided a manual with full schematics. While I would expect that upgrade kit is difficult (impossible?) to find I imagine it might be possible to use a 10811-60109 oscillator and recreate the other PCBs. Another question I had is whether the 60109 is mandatory or another 10811 could be used in its place. The 60109 sometimes shows up in the secondary marketplace but is harder to find than other variants. If another variant can be used what characteristics are important to consider and which variants might be suitable? The specifications for the 60109 are documented so ideally a replacement would perform as well or better in ADEV and phase noise. The 10811D/E seems to have similar specs though worse ADEV at 1s. On the other hand, the phase noise is a bit better for the D/E.
