Acterna DSAM-2500A Digital Service Activation Meter
The Acterna DSAM is a high-speed data installer meter that increases the number of cable modem installs per day. Using exclusive digital signal processing and integrated DOCSIS/EuroDOCSIS chipset technology, the meter communicates with the network CMTS to verify suitable conditions for cable modem installation from the subscriber's location. The DSAM is also equipped with signal level meter capabilities, including spectrum scanning for ingress assessment and mini-scan analysis of up to twelve analog and/or digital channels. The meter's AutoTest capability makes installations easier and more reliabe than ever before.
