Timing
The SYSTEM TIMING controls (or GENLOCK controls) are used to modify the timing of the video outputs from the
installed MicroSYNC cards, so that correct system timing is maintained when the unit is used in conjunction with other
video processing equipment. When a reference video signal is connected to the selected (installed) MicroSYNC
reference video input, the outputs from that card will nominally be co-timed with this signal. Using the GENLOCK
controls, the installed card output video may be shifted with respect to the reference video input.
H-POS
This button enables the horizontal position of the video signal to be adjusted +/- 1 us by using the shaft encoder. The
MicroSYNC horizontal position may be adjusted only when the MicroSYNC is configured for Line Lock mode (See
the MicroSYNC user's manual).
C – F (GENLOCK TIMING)
This button enables the horizontal genlock timing to be changed via the shaft encoder. When the Coarse C genlock
timing LED is lit, the shaft encoder moves the output video signal in steps of 270 nsec, or 360 degrees. A flashing C
LED indicates that the selected unit is not genlocked.
The F (fine) button enables the fine genlock timing to be changed via the shaft encoder. The fine genlock timing moves
the output video in steps of 0.55 nsec or 0.70 degrees. A flashing subcarrier F LED indicates that the selected unit is not
genlocked.
To disable accidental genlock timing adjustments to the input reference signal, see CONFIGURATION OPTIONS later
in this chapter. If genlock adjust is disabled, no timing adjustments can be made until it is re-enabled.
WHITE CLIP (VS-2410 Only)
This feature must be enabled from the CONFIGURATION menu before any adjustment is possible. The following
page describes how to enable the WHITE CLIP feature from the CONFIGURATION menu.
Press and hold the GENLOCK TIMING button until both LEDs begin to flash. Use the shaft encoder to adjust the
WHITE CLIP level. The usable range is +/- 20 IRE where each detent, while moving the shaft encoder, represents a
change of 1 IRE.
BLACK CLIP (VS-2410 Only)
This feature must be enabled from the CONFIGURATION menu before any adjustment is possible. The following
page describes how to enable the BLACK CLIP feature from the CONFIGURATION menu.
Press and hold the H-POS button until both LEDs begin to flash. Use the shaft encoder to adjust the BLACK CLIP
level. The usable range is +/- 20 IRE where each detent, while moving the shaft encoder, represents a change of one
IRE.
