[time-nuts] FSA3011 Frequency Stability Analyzer, HP 8405A or TAPR TIC

[Magnus Danielson]

Hi,

If you sample continously and decimate the data properly you avoid the
dead-time issues and get results which is translates well into ADEV
measures.

Cheers,
Magnus

After seeing some small reference somewhere I looked at the HP 8405A on ebay and the price range seemed comparable to the FSA3011. Now the HP 8405 is a huge beast but i was thinking that it might be easier for me to use.  I'm interested in just 5 and 10 MHz oscillator comparison.  I know nothing about computer programs or writing any code.
