Go to "SPECTRAN NF-3020". There it says " This extended version of the
SPECTRAN NF-3010 also allows analysis of EXTERNAL signal sources via
its SMA input.".
Or click "COMPLETE description". In the NEW window you can see in the
"Overview of features SPECTRAN=AE LF spectrum analysers" under "
INTERFACES" the feature "External signal input (screened SMA input)".
Got it?
With the SMA input you can feed what ever you want. Its like a SCOPE!

Right, but what is the noise floor on that at low frequencies?

If I send it DC to 100 Hz info, can I display it, and more importantly
how high is the noise floor down there and how small a bin can I create?

A lot of newer RF spectrum analyzers are rated to work down to DC, but when
you actually try it, the experience is not a pleasant one.
