Black Box MWU2000-G703, MWU2000-X21 Channel Tracer Rssi per channel, Modem Rate Vs. Buffer Size

2.048Mbps Wireless Modem

Table 3-15. Modem Rate Vs. Buffer Size

•A high number of RADIO NO RX BUFFERS that are relative to the number of the RADIO ERROR BUFFERS indicates the existence of problems in one or more frequency channels.

•It is recommended to have RADIO BUFFERS ERROR RATE under 2% (2e-2). High error rate indicates bad reception conditions. High error rate combined with a relatively high number of not received buffers indicates weak radio signal or existence of an interfering signal source.

The “Error correction algorithm” graph indicates the expected Bit Error Rate after error correction of the Wireless Modem versus RADIO BUFFERS ERROR RATE. See the description of the Error correction algorithm in the Technical Specification.
