[SBE] HDRadio Spectrum Analyzer

[Jerry Paonessa]

We have two of the LPT-3000 analyzers that Cris Alexander refers to, and they are pretty good for the price.  As with any sensitive device, however, beware you do not overload the front end with strong signals.  Aside from the obvious potential for damage, it can also cause false image frequencies that will have you chasing your tail for hours!
 
I especially like the ability to store screen shots, traces and states (a specific setup mode that you can recall quickly).  You can store info in the analyzer itself or save them off to a USB Flash drive.  Only disadvantage I can find is that it could not see my 1 Gb flash.  I had to resort to an old 32Mb gimme drive, which worked like a charm.  You don't need much of a drive because everything you're going to store will be a small file.
 
It has a convenient handle on the side that makes it conveniently portable, but I did not like the absence of battery power.  This bad boy wants 100-240 VAC, 50/60 Hz, 80W, so if you plan to use it for field measurements as we did, pack a nice healthy inverter to keep awake.  A battery pack is listed as an option but we did not know about it when we ordered the units.
