My Google fu is weak tonight.
I'm out in the field getting ready for the ARRL VHF/UHF contest. Thought I'd
bring along the bits for my 10GHz transverter and assemble it during the
downtime.
But I'm being thwarted.
Does anyone have the pinout for the six pin Datum 10Mhz oscillators?
Thank
I remember cobbling together a home brew phase noise system 35
years ago using an HP3582 FFT analyzer. It had several available
windows: IIRC: flat top, rectangular, and hamming (hanning? I can
never get them straight). Basically, if you are looking for spurs, you
need to use the flat top.

Hoi Jim,
You know, you have this peculiar way of asking seemingly simple
questions that are very hard to answer? :-)

Hi
If you sit and watch most commercial gear, they go for the “we need more data”
approach.
Put another way, you don’t get 10 Hz data up on the screen in one second. It’s
more like 10 to
100 seconds (some gear can be painfully slow).

Using the thunderbolt here.
I only asked because a co-worker spotted the altitude and thought it was
"wrong" for boulder.

Say you have 1 second of sampled data (so the FFT resolution is 1 Hz).
If you're interested in the noise power at, say, 10 Hz away, a
rectangular window isn't going to be very far down, unless you have a
LOT of poin
Hi all,
I have posted here my experience with the installation of the band pass filter
in front of the lamp of the HP5065A.
