AVQ1020 - ActiveCore® RF Layer Monitoring Receiver and Signal Analyzer
Based on ActiveCore® Platform, AVQ1020 is a monitoring receiver and signal analyzer for all major digital broadcasting standards including proprietary modulation schemes. It has been designed as an easy-to-use and cost-effective solution for monitoring digital transmitter system performance. The receiver can be integrated into a transmitter system for remote monitoring applications or used as a stand-alone unit during design verification, production tests and system calibration.
“Yes, it [AVQ1020ATSC] is now installed at its “final resting place” at KSMO’s transmitter. I’m pleased with its performance. It immediately allowed me to make improvements in the transmitted mask shoulders by allowing me to see the changes I made in the exciter." MR, Broadcast Engineer

In the context where broadcasters are more and more concerned about reducing their network OPEX costs and at the same time limiting impact on the environment, it becomes important for the transmitter systems and repeater networks to be designed as reliable as possible in terms of the QoS provided to the service subscribers.
The receiver allows not only monitoring signal parameters but it can also be used for estimation and characterization of the transmitter system performance - distortions introduced by the amplification and filtering chains. The unique functionality allows the receiver to be also used for estimation of critical RF parameters of high power amplifier performance using real broadcasting signals.
The ActiveCore® RF layer monitoring receiver is available as a stand-alone unit (1U) or an OEM module.
Monitoring and measurement at RF Modulated Layer at the transmitter output;
Real performance metrics of the transmitter system;
Combination of functional and measurement capabilities with cost effectiveness of the Receiver/Analyzer guarantees the ideal solution for monitoring RF signal quality of remote transposers, re-broadcast links, repeaters, and unmanned sites without additional costly RF test equipment;
Comprehensive set of critical RF measurements including signal MER/SNR, frequency spectrum, shoulder attenuation, frequency shift, etc.
Estimation of signal distortions at the transmitter system output caused by the system non-linearity - AM-AM/AM-PM curves and band-path filtering - group delay, amplitude and phase responses with an ability to use the estimated numbers in a form of complex LUT and FIR for non-linear and linear pre-correction;
