Delta carrier levels are typically expressed in dBmV (decibels millivolts) in Cable Television and telecommunications systems. This unit of measurement provides a logarithmic representation of the change in signal levels between carriers, making it easier to analyze and troubleshoot signal quality and noise levels in the system.
5 mv is 14 dbmv.
dBmv is defined as 20 log (V/1mV) where V is the voltage converted into dBmv if X = 20 log (V/1mV) then V= (1/20) Antilog (X)

To check the coax signal strength and quality in your cable connection, you can use a signal strength meter or a cable modem diagnostic page. Connect the meter to the cable outlet and check the signal levels for both strength (measured in dBmV) and quality (measured in SNR or MER). On the cable modem diagnostic page, look for signal levels and error rates to assess the quality of the connection.
