Product information
The RSSI monitor in R&S®AVQA provides a great opportunity for long-term signal and noise monitoring of the radio infrastructure. Using the flags in the ED-137 voice stream, R&S®AVQA non-intrusively analyzes the RSSI level. Based on the squelch information, R&S®AVQA automatically differs between the signal and noise and reports this accordingly.
