2.2. Downstream RF
This function shows the spectrum of the
downstream RF signal.
The spectrum has a great level of detail, so it is
a goof tool for identifying noise, interferences,
ingress and other waveforms that may be affecting
the quality.

2.1. DOCSIS Scan
This function scans the selected channel plan
and detects every existing SC-QAM and OFDM
channels in real time
The scan measurement leverages the location
based thresholds to clearly show whether or
not signal levels comply with the cable system’s
specifications with their green, yellow and red bars.
This gives an easy-to-understand real-time view of
the system, including the BER and MER values of
the selected channel.
