The 3SR Receiver, in addition to performing its sweep reception

duties, conducts a battery of signal level measurements, including a

full scan of the cable spectrum to 1 GHz. A proprietary digital signal

processing (DSP) technique is used to measure hum and carrier to

noise on modulated carriers.

The 3SR Receiver is a full-featured signal analysis meter, with a

complete spectrum display and an analog representation of single

channel measurement data. When tuned to a specific channel, a

comprehensive set of information is provided: tuned channel, video

frequency and level, audio frequency and level, the difference

between video and audio carrier levels.

The 3SR Receiver is a streamlined, hand-held instrument, that

weighs less than five pounds. Its 320 X 240 dot matrix LCD shows

measurement data in both graphical and numerical form.
