Re: Advice for a new to me Spectrum Analyzer
CAREFUL - There are both 50 and 75 Ohm N connectors. Mis-mating them
results in distruction of a 75 ohm connector.

A 50 ohm instrument will have a type 'N' input connector.? A 75 ohm instrument will have a type BNC.
Look at the option slots on the back.? You might have I/O ports - either serial + parallel or?
