The Promax PROMAX-37 Cable TV Multistandard QAM Analyser incorporates the most advanced functions in accordance to updates made on thelatest version of the DOCSIS 3.0 protocol, which includes channel bonding technology, allowing the instrument to be adapted to thelatest technologies implemented by data over cable network operators.

Channel bonding technology divides the data stream packets in order to sent them simultaneously through multiple independent channels. At destination they are again sequentially reordered. The result is a bandwidth equal to the sum of allused channels. By this way, the whole bandwidth increases by using the existing infrastructure of the data network. The channel bonding allowsboth the data traffic sent to a cablemodem travels through several downstream channels (Downstream channelbonding) as the traffic generated by eachuser returns through several upstream channels (Upstream channel bonding).The channel bonding function of the PROLITE-37 Cable TV Multistandard QAM Analyser can measure and checkcable networks that use this technologyin both directions.

The PROMAX-37 Cable TV Multistandard QAM Analyser also incorporates the Sweeper function, which can test and adjust tilt and gain of the upstream distribution amplifiers and detect any failure in the system caused by the imbalance of any of these parameters.
