ISO-TECH ISA 830 TG: viewing a GSM base station carrier

When I received the ISA 830 TG spectrum analyser the first thing I did was to connect a small antenna from a USB DVB-T receiver, and use it to look for the signal from a GSM femtocell which was located about four feet away.

You'll have to excuse the flickering, which is due to the camera not getting on with flourescent lighting.
