Description
NDBPNTR returns a -100 if the NDBPNT function has not been turned on, or if NDBPNT did
not find a signal to measure. (For NDBPNT to be able to measure a signal, there must be an
on-screen signal that is greater than the peak excursion above the threshold, and there cannot
be any other signals with amplitudes that are within N dB of the peak of the highest signal.)
