I played with the science workshop spectrum analyzer=20
many years ago and wasn't all that=20
happy with it. I don't remember the details but one major problem=20
was inability to calibrate the frequency accurately. It was useful=20
to get a general idea of what the spectrum looked like but that was=20
about it. The last time I used it was probably 10 years ago.
I've been using an old HP 8559 for the past many years but late last=20
year, I finally bought something better: its called a Signal Hound=20
. I also purchased its companion tracking=20
generator when they became available early this year. Both go up to 4.2GHz=
..
If you do purchase one of the Signal Hound units used, make sure that=20
you get the "B" version. The earliest units (non "B") spew=20
significant amounts of the first LO out the input connector which can=20
(DID!) cause significant problems.
I also recently purchased a VNA (vector network analyzer) from=20
. This is a NICE little box that does one and two=20
port measurements. It will function as a rudimentary spectrum=20
analyzer but there are limitations that are at least well=20
documented. Its good up to 1.3GHz.
Both of the units I mentioned are fully assembled, not kits and not=20
parts collections that can be gathered up. Sorry about that. But=20
they both work well.
