4–31

al. Check that the F1L7 delays eight lines from the original starting point.

am.Return the delay on Black 1 to 0 lines.

an. Display CH B1 on the waveform monitor using the same settings as

CH A.

ao. Repeat the above procedures for Black 2 (CH B1).

26. Horizontal Timing Offset Range

1/2 video line

a. Set up the equipment as shown in Figure 4–7.

b. Set the SPG 422 to output PAL black burst with no horizontal offset on

both Black 1 and Black 2.

Display CH A and CH B1 on the waveform monitor in 1 line overlay
mode using external reference.

d. Set the SPG 422 Black 1 to its maximum horizontal advance.

Check that the CH A signal advances at least

line relative to the

CH B1 signal. (You may need to use the fine horizontal timing to get to
the full

line offset.)

Set the SPG 422 Black 1 to its maximum horizontal delay.

g. Check that the CH A signal delays at least

line relative to the CH B1

signal. (You may need to use the fine horizontal timing to get to the full

line offset.)

h. Return the SPG 422 Black 1 horizontal offset to 0.

Repeat the above procedure for Black 2 (CH B1).

Repeat the procedures 20, 21, 22, 23, 24, 25, and 26, except with the
following signal changes:

Replace Black 1 and 2 with Black 3 and 4.
Connect Black 5 to CH B2.
Connect Black 6 to CH B3.
Extend all procedures to include Black 5 (CH B2) and

Black 6 (CH B3).
