Description
The External CM / Upstream Spectrum function extracts a sample of the
upstream signal and displays its spectrum on the screen. Connect the
CABLEMODEM to the "EXT CM" input and the cable from the CMTS to the "RF"
input. The equipment works as a bypass and the display shows the transmission
signal (bursts) from the CABLEMODEM to the CMTS. It is recommended to
enable the peak detector to view bursts better.
