10.9 Configuring Lip Sync
Combining the LT 4600A and our waveform monitor LV 5770(A) makes it possible to measure
the offset between the video signal and the audio signal that occurs in the transfer route for
each channel. Prepare an LV 5770(A) with an LV 5770SER08/09A and LV 5770SER41/43
installed. For information on how to use it, see the LV 5770SER08/09A instruction manual.
