: [time-nuts] FSA3011 Frequency Stability Analyzer
If anyone else has a FSA3011 please contact me, off-list. It seems to
function on split-signal noise floor tests, but has real trouble with
tracking and comparing actual oscillators. More details soon, but in case
it's just my unit, I'd like to talk

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.

I have an 8405, fortunately in excellent condition, along with the BNC adapters,
the resistive splitter and the 50-ohm line samplers. The probe tips are very
delicate and are probably unobtainium these days. The electronics in the probes
can be repaired. I've been careful with mine and had
Hi
The 8405 is a fine device and with working probes can be very useful to have
around. Without the
probes .. not so much. Since they have been around since the 1960’s, the probes
may have seen
quite a bit of wear and tear.
For comparing standards, an RPD-1 and a DVM will kind of / sort of do

Yo Bubba Dudes!,
I've been following the discussion of the FSA3011 with great interest.
Now I'm not in the upper levels of TN esoteric knowledge or have a burning
desire to ever get there. After seeing some small reference somewhere I
looked at the HP 8405A on ebay and the price range seemed

Wha's the problem? If it's just running out of high order bits in a counting
register, I can fix that with a

Yes, I'm evaluating a FSA3011 at the moment. It's a cute little unit.
Documentation is sparse, the jpg plots are fuzzy, "customer" support is

Hi
One of the questions earlier was about the “offset oscillator” in the device
and if it was tuned in any way.
If it is not tuned *and* it has modest stability, the exact frequencies you put
in may impact the performance
you get. Since there seems to be zip for command set, I’d bet there is no

Hi
There was some chat a few weeks back about them and several questions came up
about some of the features of the unit. I believe there was an inquiry into the
people
making the device to get some further information. If that *did* come back and
get
posted, I missed it.
