It is pretty impressive for 10 oz of weight. Thats also a reasonable price
if you did not have the big iron big power units.

I found the Signal Hound while searching for a baseband analyzer, to be use
in phase noise measurements.
Don, do you have tried it? maybe using an external low noise ref?
Any other member tried it?

Tks, folks.
I saw the diagram on the manual, albeit a bit too simplified
but ok, indeed we can have an idea.
For LO I suspect that might be one of those clock generators IC with VCO
+ PLL plus a a lot of programmable dividers and really would match the
simplified diagram they have

The Signal Hound is an interesting gadget. It's far more "portable" than my HP
8594E! And yes, the 10 MHz ref input on the back does help; without an external
reference it does tend to wander around.
Their website says they've replaced the original model with a rev "B" which
adds a preamp and

Page 27 of their manual at http://www.signalhound.com/manual.pdf has a block
