Stealth Sweep Transmitter Wavetek 3ST


* 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
