20 8981FS Instruction Manual

8981FS Digital Frame Synchronizer Module

Module Operation Mode Selection

Access the Mode display shown in Figure 10 to perform the following

(refer to Module Operation Modes on page 10).

■ Choose between Frame Synchronizer or Delay mode.

Note If a sync reference signal input is not detected by the 8981FS, the module will

automatically function as a ﬁxed video signal delay. In this case, the Operating

Mode indication in the display may read “Frame Synchronizer” when the

module is actually functioning in delay mode.

■ If in Frame Synchronizer mode, choose the output that will be active if

the input signal is lost—pass the input channel or force the output to

black.

■ Pass or blank switching line and vertical interval data (see Switching

Line Handling and Vertical Interval Blanking on page 14).

■ Select EDH error detection mode (see Input Signal EDH Detection on

page 12).
