Connecting the Equipment
Connect the measuring instruments as shown in Fig. 5-3-1 according
to the input terminal (VIDEO jack input or DV jack input), and
perform the adjustments.
The input terminal is specified in the ( ) in the signal column. Either
input terminal can be used when there are no specifications.
The order of priority of the input signals is shown below.

[How to generate the color bar signal]
1)
Connect the adjustment remote commander to DCR-VX1000

Select page: 5, address: 02, and set data: 09.
By carrying out the above procedure, DCR-VX1000 (NTSC)
or DCR-VX1000E (PAL) generates the color bar signal. After
completing adjustments, set data: 00 to the address.

Checking the Input Signals
Because the video signal obtained from the pattern generator is used
as the adjustment signal for adjusting the video system, the video
output signal must satisfy the given specifications.
Connect the oscilloscope to the VIDEO jack, and check that the
sync signal amplitude of the video signal is approximately <0.286V>
[0.30V], the amplitude of the video section is approximately <0.714>
[0.70V], the amplitude of the burst signal is approximately <0.286>
[0.30V] and flat, and that the level ratio of the burst signal to the
“red” signal is 0.30 : 0.60.
The video signal used for adjusting the video section is shown in
Fig. 5-3-2.
