Solution
• Verify the RF configuration settings.
• Verify the USB cable connection in LCS.
Check whether the USB cable connect correctly and refer to
High Output Intelligent Node Software Installation and Configuration Guide
see whether USB connection mode on mobile phone has been configured
correctly.
• Check if the headend performance meets system design target.
• Measure level of RF input to RPD and check if the RF input level is correct.
Look at the reverse path to determine which port(s) are noisy. Using max hold
makes it easier to see bursty noise signals.
