Description
PCTAMR returns a -100 if the PCTAM function has not been turned on, or if the on-screen
signal is not valid or is not present. PCTAM can perform the percent AM measurement only if
there are three on-screen signals that have the characteristics of a carrier and two sidebands.
Also, to be considered a signal, the levels of the carrier and sideband signals must be greater
than the peak excursion above the threshold.
