I am nonplussed to discover that hours of web-surfing have not brought me
to a source for an RF (50 ohm) sweeper that will cover a little past 500
MHz. There are used sweepers available (will a 75 ohm Wavetek work? I do
not understand the concept of impedance - I used to think it was like
resistance) and I can get a dual-band 10-500, 450-950 Wavetek for about
$1600 reconditioned, but it says for CATV, 75 ohm.
I do not need 40 GHz. Why doesn't anybody make these mid-range sweepers
anymore? I have waited 12 years for one, can finally swing it, and now I
have to hunt through the scrap piles, it seems.
Someday, I hope to put a GPIB card on a PTS and use labVIEW or somesuch to
turn it into a sweeper, but I have A LOT to learn between now and then.
(And just when I am studying Wildavsky on "The Politics of the Budgetary
Process.")
