Checking the Signal Level with an RF Power Meter
(Optional)
The CMAP cable modem is just like the standard DOCSIS 3.0 modem installed at
home.
Connect an RF power meter to the cable from the cable power tap.
Select a CATV power passing tap that supplies a signal level between -12 and
+16dBmV at its output (prefer 0 to 6dBmV).
lists the signal level specifications to coaxial cable connector on the CMAP.
