RF Monitoring

With Tektronix Video Quality Monitors

Monitoring the edge of your network is important for catching modulation errors that could impact the quality of service you provide to your subscribers. Tektronix Sentry Edge products detect transport stream and RF modulation errors generated from equipment errors or failures.

Tektronix now provides advanced RF monitoring with Sentry Edge II.  Sentry Edge II is a high-performance, scalable solution for post-QAM monitoring in the dynamic video environment, where quick problem isolation and resolution are essential.  Sentry Edge II can be used at the hub, headend or wherever QAM is used.  Comprehensive and industry-leading high-quality RF measurements make it easier and faster to pinpoint issues. The RF measurements include RF lock indication, input signal level, error vector magnitude, modulation error ratio, carrier to noise, pre-FEC bit error rate, post-FEC uncorrectable TS packet count and carrier offset. Constellation diagrams are provided for diagnostics.

Additional service monitoring capabilities are available for QAM channels in the clear, including audio/video QoE, perceptual video quality (PVQ), and Ad Verification as well as EBIF, tru2way™, MHP and DSM-CC carousel analysis.
