In-Band Analysis for Terrestrial Broadcasting
Avateq introduces in-band analysis as a standard feature of AVQ1020 - RF Layer Monitoring Receiver.
Modern transmitting systems and networks rely on sophisticated structures to ensure robust signal broadcasting and compliance with regulations such as frequency allocation, etc. The quality of the signal depends on the properly adjusted and tuned transmitting system. Some of the hidden and often hard to detect sources of signal deterioration are non- and linear in-band distortions, signal clipping, in-band spurs and limited bandwidth noise. To address these issues, Avateq introduces in-band analysis as a standard feature of AVQ1020 – ActiveCore RF Layer Monitoring Receiver. Analysis of in-band distortions and interference is a powerful tool for transmitting and communication system troubleshooting and performance optimization. With the new functionality, the undesired causes of SNR degradation including an unwanted signal buried under the main lobe can be easily detected.
Examples of signal deterioration:
No in-band distortion.
ATSC carrier buried
under the main lobe
The unique ability to estimate and visualize the in-band distortions makes the introduced functionality irreplaceable tools for linearization techniques development and intermodulation products characterization.
