Displaying Frame Capture Data
You can display the captured frame data on the LV 7770 or overlay it on the current input
signal. You can also display the frame data in different display modes.
To select the display mode, follow the procedure below.
•
First, set the display mode to video signal waveform display, vector waveform display
(except for the 5 bar display), or picture display.
•
To display frame data, the LV 7770 must be receiving a signal whose format is the same
as that of the captured data.
•
The display may blink when you change the display area or operate the V POS knob, H
POS knob, or function dial (F•D).
•
The scale and measured values are those of the current signal, not those of the captured
data.
