WAVETEK JDSU Acterna SAM 4040 Signal Analysis Meter With Forward Sweep
The Wavetek hand-held SAM 4040 performs essential cable TV system preventive maintenance tests with accuracy and ease. Signal levels, hum, C/N, and frequency response can be quickly tested.
The SAM 4040, 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.
It is a full-featured signal analysis meter, with a complete spectrum display and 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 SAM 4040 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.
