Below are some more examples of how to use the oscilloscope:
As a High Frequency Headroom Monitor:
Display the Left or Right Demod signal from the MPX Output menu
♦
Set Oversampling to "On"
♦
Set Phosphor Persistence to 50
♦
Set Gain to -3
♦
Set Lines to -1
♦
Set Zoom to 4x
♦
Below is a comparison of this signal to the L/R pre-emphasized output (the one you'd be using if you used an external stereo
generator, whether fed with Analog or AES/EBU) so you can see just how much additional HF headroom Omnia.9's own stereo
generator provides!
As a Pilot Protection Monitor:
Display the MPX Output
♦
Set Oversampling to "Off"
♦
Set Phosphor Persistence to 40
♦
Set Gain to 0
♦
Set Lines to 0
♦
Set Zoom to 8x
♦
Note that what you are seeing here is the actual pilot extracted from the entire MPX signal. Note the complete lack of pilot
modulation despite basically all the clipping happening in the composite domain.
