CW is a special test mode not used in regular operation. The CW mode generates a
narrow-band frequency tone. This is useful for phase noise measurements or to view
background noise.
Transmission
The Transmission page allows the user to enable/disable ATSC-MH waveform support,
enable/disable SFN network operation and configure parameters from the information
imbedded in the TCP. The Transmission page will change dynamically, depending on
enabled/disabled modes.
