OEM QoS Measurement Probe


The RQX-1000 is a very innovative OEM solution especially designed to perform the Terrestrial Digital TV signal quality measurements. Broadcasters are becoming more and moreconcerned by monitoring their Digital TV network infrastructure as they are developing a global Quality Of Service (QoS) approach. One critical part of a DTV infrastructure is the transmission sites and the DTV transmitters. The demand to monitor the QoS figures for DTV transmitters is therefore increasing and the global strategy of TeamCast is to address those needs with a very compact solution offering best class of DTV signal monitoring features.
RQX-1000 consists in a compact size OEM module, ready to be integrated within transmitters or within QoS integrated solutions. It includes a DTV demodulator to perform signal decoding to supply stream output. Additionally, a front-end low noise tuner is implemented to authorize high performance of MER measurement that is commonly requested for QoS monitoring purpose. To ease its integration within QoS completed system, RQX-1000 features an IP over Ethernet port used for both product control and streaming output. RQX-1000 product family consists of several models covering DVB-T/T2 and ISDB-T/TB applications.

Exhaustive set of monitoring features

RQX-1000 provides a large choice in term of retrieved monitoring parameters and data.
Typical RF signal performance figures such as Input level, MER, Signal to Noise ratio (C/N), Bit Error Rate and Packet or Frame Error Rate are collected in real-time. Furthermore, the user can upload more complex and added-value measurement data such as the RF signal spectrum display, the I/Q constellation diagram, the signal power bar graph as well as the SFN Window.

Compact and easy to integrate

As with all TEAMCAST modules, the RQX-1000 product consists of compact and powerful OEM unit, especially designed and developped for fast integration. Designers can elect to manage the RQX-1000 by using an opened and simple communication protocol accessible either via the serial port or via the IP interface. RQX-1000 supports both RF input and ASI input interfaces in order to monitor the transmitter input stream in one hand and in the other hand the radiated RF signal. This in particularly saves the need for the integrator to install an additional ASI interface board within its own design.
