AVQ1020 - ActiveCore™ Multistandard Monitoring Receiver

Introduction

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 design 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 and production tests.

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 that the repeater networks are designed to be as reliable as possible in terms of the provided QoS.

Parameters are measured by the receiver and can be requested by a remote host or Repeater System Management Centre in remote applications. The receiver allows not only monitoring broadcasting signal parameters but it also can be used for estimation of performance of the transmitter system - distortions introduced by the amplification and filtering chains. The unique functionality allows the receiver to be used for estimation of critical parameters of high power amplifier performance using real broadcasting signals- signal compression (peak clipping), amplifier and phase non-linearity, memory effects, etc. Another application of the receiver is analyzing signal propagation environment including multi-echo path and air-channel influence.

The ActiveCore monitoring receiver is available as an OEM module or PCIe card in an instrumental PC.
