Upstream Analyzer is a software-based analyzer that works with Cisco CMTS. There is no need for any expensive equipment, splitters or cables to view the upstream spectrum passing through the CMTS. You can view spectrum for 100% of the ports 24 x 7 x 365 anywhere you have Internet access. You can even view ingress under the carrier with one click. There is no need to move a cable modem to a different frequency to see what’s going on. Upstream Analyzer takes up no space in your headend, and is much less expensive than hardware-based spectrum analyzers or monitors.
