SCOPE INFO HELP

[soundnmind]

Hi Fellow AM'rs
While back I picked up a couple of scopes & need books on each. My need is a
monitor for AM.
1. Tek RM 503 Seems this scope is primarily for audio for
        veticle display only responds on 160m band &
        below. For you TEK experts, is this its limit?

2. Sencore PS 120, says its useable thru 12mc. But it
        doesnt work. So I need documentation. CRT is
        only 3" but still useable.

Any info is appreciated........
Regards
