3. System Scan
This function scans the selected channel plan and
detects every existing analog and digital channel
in real time to determine the overall frequency
response of the system.
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.
