Signal level Meter

Terryscan 2 - Swires Research

The Spectrum mode enables viewing of the full VHF-UHF
band (or any part of the band) in real time and allows fast
checking to ensures that all channels are available. This is
much quicker than looking at individual channel readings on a
conventional meter and allows the rapid identification of cable
and connector problems. Favourite settings may be stored for
rapid retrieval. The spectrum display also has a peak hold function,
very usefull for tracking intermittent interference including
that from the 800 MHz LTE band.
