DSAM-2500B

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.

Highlights:

• All-in-one meter includes DOCSIS/EuroDOCSIS service testing and SLM features.
  
• Autotest capability with administration security.
  
• Environmental resilience and robustness.
  
• Extensive help system directly linked to meter capabilities.
  
• Multiple language support.
