Having a spectrum analyzer sounds fun. Will it show the freq field

everything broadcasting at the moment, or be tuned only to the radio

other
than to tune/verify a radio transmitter freq or such.

They are more useful than oscilloscopes for working with RF, nearly
useless for almost anything else. Actually the instrument I used most
at Mitre was a network analyzer which applies a frequency-swept signal
to the input of a circuit and measures the output.

The RSP1A sweeps over a maximum of 10MHz so one 6 MHz wide HDTV
channel takes up most of the screen. You can place the mouse cursor on
any digit of the frequency display and roll it up or down with the
mouse wheel to move the on-screen frequency band.
