Hello all,
I'd like to purchase or rent a milesdesign TimePod 5330A Programmable Cross
Spectrum Analyzer.
Rental would be for a duration of a few to several months (can be agreed on), in
this year. Careful treatment of the device will be assured.
My application is the measurement of phase noise of ultrapure microwave signals
generated by a femtosecond laser. This state-of-the-art approach produces
ultra-low noise microwaves. The goal specifications are -70 dBc/Hz at 0.1 Hz and
-90 dBc/Hz at 1 Hz, -110 dBc/Hz at a frequency of 9 GHz.
This would require down-mixing, and the TimePod can do that, but the
larger Symmetricom boxes can't handle it. with down-mixing I mean that
after splitting the signal, two mixers with a pair of 8,99 GHz signal
sources (to make the signal about 10 MHz) should do it. You also want a
quiet reference oscillator. Got to try this one myself one day.
The Symmetricom version of the TimePod does not have the capability of
measurement at 0.1 Hz offset frequency, therefore I am looking for the original
device.
Good point.
Can the Symmetricom version grab data so it can be presented by the
TimeLab with that range?
Cheers,
Magnus
