Continuously referenced, non-interfering sweep frequency response measurement
Extremely fast sweep update
Receiver is also high-powered SAM
Hum and carrier to noise tests on modulated carriers
High resolution LCD spectrum display
Performs essential cable TV system preventive maintenance tests with accuracy and ease
Signal levels, hum, C/N, and frequency response can be quickly tested without subscriber interference
Frequency response is tested by injecting a low level signal in vacant spectrum areas, and monitoring cable system carrier levels in occupied spectrum areas
In addition to generating the sweep test signal, the Stealth Transmitter 3ST continuously monitors the system carriers
While monitoring these carriers, the 3ST immediately sends any headend level variations to the Stealth Receiver 3SR
Stealth Receiver, 3SR, 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
