3SRT
Highlights:
- 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
