Wavetek SAM 4040 Signal Analysis CATV Meter

Description

Wavetek SAM 4040 Digital Analyzer
W avetek’s SAM 4040, a next generation signal analysis meter, is more like a hand-held broadband communication service monitor, with a broad scope of practical test capabilities. It performs essential cable TV system preventive maintenance tests with accuracy and ease. Signal levels, hum, and C/N can be quickly tested without interrupting subscribers’ reception. In no time, technicians are up and running the full range of tests with unprecedented speed. The hand-held, lightweight, rugged, and water resistant SAM 4040 utilizes down-sized electronics including surface mount components and multilayer PC boards. The measurement information is clearly displayed on a high resolution (320 X 240) LCD. The SAM 4040 is the first signal level meter available with Wavetek’s trademarked Sweepless Sweep®, in which active system carriers are measured and compared to a stored reference to determine system frequency response. In addition to its sweep reception capabilities, the SAM 4040 performs a battery of signal level measurements, including a full scan of the cable spectrum to 1 GHz, and a built-in spectrum analyzer with spans from 3 to 50 MHz. A proprietary digital signal processing (DSP) technique is used to measure hum and carrier-to-noise on modulated (unscrambled) carriers.
