R&S SA infos

Hello,

I'm sorry for crossposting, but I need fast infos if available.

I've the opportunity to acquire for a good price a not so young
Rohde&Schwartz spectrum analyzer :

Polarad 632C-1

Unfortunately, I can't find any infos about it, except I was told it's a
100KHz-1GHz one, and I've got pics of the front and rear panels. But still I
find these infos somewhat meager.

Of course I've googled, tried R&S site and... not avail.


Any info here, advice from who used one...


Thanks,

Fred.

G'day Fred.
On my travels, the nearest I've come across, is the "632A-1" model
(there's
also 630-631-640-641 models). This SA is from the '600' series and is a
100kHz to 2GHz version with span from 500Hz to 200MHz per division and and
a
general good quality spec' (including digital memory). Price in 1978 was
$8000. The 600 series models all seem to run upto the multi-gig area.
Don't think though, that they're from 'R&S'. The circuit diagrams look
remarkably as if they have been drawn by Tektronix people.

John,
thanks for the info.

Did you used them ? Do you have any comments/feeling about the behaviour of
the beast ?
Comments like :
- freq stability (it's not synthetised, so who knows)
- phase noise (should be low enough as it displays a resolution BW down to
300Hz)
- dynamic range
....


After some more googling, it appears that the 6xx model numbers are from a
firm called Polarad Electronics Corp that makes (made?) all sort of mwave
stuff.

But the pics clearly show a R&S/polarad logo and model number 632C-1.

After a bit more of search I found 2 (only!) patents (1985&1986) at uspto
that show the names R&S and Polarad associated. So there seems to have been
a merge.

Fred.

Probably too late now ... :)
Nearly bought one (in poor condition) at Ł100 a couple of years ago. Had
chance to play with it and found it acceptable signal-wise but
the construction quality indicated they were built down to a cost. Ended up
buying an ex military Marconi unit.
From the '631' manual, which probably shares many components with the 632
(I just love equipment manuals!) ...

Spans below 100kHz force a crystal phase lock to the first LO.
(Quote from page, "high degree of stability and low residual sidebands")
Drift when phase locked: +/5kHz in a 10 minute period. (fundamental mixing
mode).
Noise sidebands (1kHz BW) >65dbm below ref signal (50kHz away).
Residual responses, <85Dbm (no input signal).
IMD, <60Db (third order, 2 equal -30Dbm inputs)
Sensitivity -110Dbm. Average noise -116Dbm. Gain flatness +/-1.25Db.
Displayed 70Db range at 10Db/div.
70Db RF attenuator.
IF Filtering down to 300Hz.

Whether it's all worthwhile of course, depends on the price of the thing
:).

Thanks for the infos. I'm not in a hurry so I think I'll wait for another
one.
