Video Demodulation Concepts (Opt. AYH)

Special considerations for pulsed signals

You can use pulse search to demodulate pulsed (burst) transmissions. Pulsed
transmissions are generated by on/off carriers such as those used in mobile units.
Pulse search is identical for both video and digital demodulation. To learn how to
use pulse search, see ''Special considerations for pulsed signals'' in the Digital
Demodulation Concepts chapter. For an example using pulse search, see
''To set up pulse search'' in the Using Digital Demodulation chapter.
Note
You cannot use pulse search for VSB measurements. The [ pulse search on/off ] softkey
(under the [ Time ] hardkey) is ghosted (inactive) if VSB is selected.
