SDI Signal Eye Pattern Measurement
•
Required Optional Unit
LV 5770SER09A(SDI INPUT/EYE)
1. Apply an SDI signal to SDI INPUT A or SDI INPUT B on the rear panel.
2. Turn the MULTI key off (optional).
The LV 7770 switches to the 1-screen display, which is easier to view. (On the
multi-screen display, one of these displays is shown.) This is not supported in simul mode
or on the multi-screen display of 3G-B(2map) signals.
3. Press EYE.
The eye pattern and jitter waveforms are displayed. Simul mode is not supported.

Composite Signal Measurement
•
Required Optional Unit
LV 5770SER03A(TRI SYNC/COMPOSITE)
1. Apply a composite signal or an HD tri-level sync signal to the TRI SYNC/COMPOSITE INPUT
A connector or TRI SYNC/COMPOSITE INPUT B connector on the rear panel.
2. Press CMPST.
The composite signal or HD tri-level sync signal is displayed. When an HD tri-level sync
signal is applied, the vector waveform and picture are not displayed.
