Selecting the Input Channel
When you are measuring an SDI signal or composite signal, press A or B to select the input
channel. Press SIM to measure both channel A and B simultaneously. However, you cannot
measure both channels simultaneously:
•
When you are measuring SDI signals on the status display or eye pattern display.
•
When you are measuring SDI signals with HD dual link or 3G-B(2map) input.
•
When you are measuring composite signals.
The input channel setting is shared between areas 1 to 4. You cannot set the setting differently
for each area.
SIM = OFF (single input mode)
SIM = ON (simul mode)

Selecting the Display Mode
The LV 7770 has six display modes: WFM (video signal waveform display), VEC (vector
display), PIC (picture display), AUDIO (audio display), STATUS (status display), and EYE (eye
pattern display). Press MODE on the front panel to select the display mode.
On the multi-screen display, you cannot set different areas to the same display mode. The
display mode that you specify last takes effect. However, VEC can be displayed
simultaneously in the vector display and 5 bar display.
The optional units that are required for each display mode are shown below.
