Timing

The timing function operates in one of three modes:

1. When the Frame Sync control is turned On and a proper reference signal is

connected to the Ref In BNC, the video output of the unit will be syn-

chronous and locked to the external reference. The output may be timed

with respect to the Ref In using the timing controls. In this case, the unit

will accept asynchronous video and time base errors will be corrected.

2. When the Frame Sync control is turned On and no reference signal is

connected, the unit will act as a time base corrector only. The output will

not be synchronous to any reference, including the input. This mode allows

a noisy input signal to be time base corrected for a clean stable output.

3. When the Frame Sync control is turned Off, any reference signal to the Ref

In BNC is ignored. The video input is synchronous to the video output when

a nearly perfect, clean video input signal is present (no time base correction

required).

The output timing of the module can be adjusted with the following controls when

Frame Sync is enabled:

Vert – adjust the vertical timing in lines in reference to the Ref In.

Hor – adjust the horizontal timing in clocks in reference to the Ref In.

Fine – adjust the fine phase in subpixels in reference to the Ref In.

TBC/Frame Sync

This control enables the Frame Sync genlock function when an external reference

is present on the Ref In BNC.

Vid Gain

This control adjusts the gain of the analog video signals in the Digital-to-Analog

converter and encoder circuitry of the converter. The right arrow will increase the

gain, the left arrow will decrease it. The Vid Gain indicator will illuminate green

when the gain is set to its nominal or unity setting.

This is the setting which will produce correct analog output levels from a digital

input source which itself is at proper level. The Vid Gain indicator will illumi-

nate red whenever the control is adjusted either higher or lower than the nominal

setting. The gain can be reset to nominal (green) by pressing both arrows simul-

taneously.
