PROMAX-26 DOCSIS analyserUpstream and Downstream

The PROMAX-26 communicates with the CMTS and shows the most important information related to the transmission: frequencies assigned in the upstream and downstream, signal quality in the downstream (power, BER, MER), power transmitted by the modem and attenuation in the return band.

The upstream attenuation is a very important parameter and the installer must verify if this parameter is within the specified range.
