Re: [time-nuts] Spectrum Analyzer Suggestions

Well Perry,

You could consider an IFR A-7550 SpecAn. They are not HP but still a 
decent little SpecAn that is just a bit bigger then a TEK-453 scope. It 
covers from 100KHz to 1GHz.

Shop carefully to make sure you get one with atleast the internal 
tracking generator option. DO NOT rely on pictures because the tracking 
generator connector is there even if no option. There is also an 
internal receiver option, but that only works when you are at zero span 
and truthfully, not all that useful, but nice to have. It also has an 
internal battery option, however, the battery pack is quite expensive 
and unless you actually need it, it is a complete waste of money. If it 
comes with a battery, expect it to not be in very good shape. The 
battery pack is made up of large round 2 volt lead acid cells and when 
left discharged will leak acid.

List,
 
I just purchased a HP 3585 spec analyzer on E bay
for a reasonable price.  I wanted this
instead of the 181 series as the range was more to what I’d be using and it 
was
of a newer vintage.  The 3585a goes from
10 Hz to 40 MHz which is a most useful range for my purposes. so far, so good.
 
The problem is I didn’t know the beast weighed a svelte
88 pounds! Double Hernia time!
 
What I’d appreciate advice for a used spec
analyzer in the $1,000 range that is at least much lighter.  A smaller size 
would also be a benefit. Â I probably would never use it above 100 MHz. A
slightly smaller screen would be OK.
 
Suggestions appreciated.
 
Regards,
 
Perrier
