NOTE.
Requires Option AVD.
View the Audio/Video Delay (AVD) display by pressing the MEAS button and
selecting AV Delay as the display type. AVD measures the duration that a video
system advances or delays the audio signal relative to its correct temporal position
in the test signal of the lissajous channel pairs.
AVD allows you to take measurements and display them in both numeric and
graphical formats. AVD measurements require an appropriate AVD sequence
signal source, such as from a Tektronix TG8000 signal generator. This capability
is useful for facility maintenance and setup applications because it allows for
out-of-service testing to quickly check synchronization across a facility. AVD
supports digital and composite inputs, and the following audio inputs: embedded,
AES, and analog. (See Figure 40.)
