The same reading cannot be displayed twice. Selection of a specific reading
changes source of nonedited field to another source
12. Distortion/
SINAD/Modulation Meter
Displays distortion reading of received signal if Distortion is selected.
Displays SINAD reading of received signal if SINAD is selected.
Displays modulation reading in units of selected DEMOD Type (5) if Modulation is
selected.
This field is interactive with Distortion/SINAD/Modulation Reading (11) and field
displays complete meter when Distortion/ SINAD/Modulation Reading (11)
displays reading only.
The same reading cannot be displayed twice. Selection of a specific reading
changes source of nonedited field to another source. One source must always be
