Dear Hamsters,

Does anyone have any information on the specification for a Hewlett
Packard HP8551B spectrum analyser.
I have read it has a very wide range but wonder if there are external
units to fully realise this.
I have the option of the display and RF unit, what will this cover on
it's own?

Thanks...

Dave


The coax input frequency range is 10.1 MHz to 12 GHz. With external
mixers and adapters to provide a waveguide input, 8.2 to 40 GHz.

This is a very old piece of equipment. More often than not, the BWO is
weak, or even bad. Unless it is an offer that you cannot refuse (like
free or real cheap), and includes the interconnecting cables, stay away
from it.
