or up if the binary value of the LSBs is 10. 8 Truncated simply removes
the two LSBs from the 10-bit signal. This mode is recommended for
troubleshooting only, and should not be used during normal operations.
With the standard Output module, there is one bit resolution setting for
all digital outputs. With the Enhanced (Frame Delay) Output module
only, there is a bit resolution setting for the Program and Preview
outputs, a separate setting for the Aux 1 and 2 outputs, and a separate
setting for the Aux 3 and 4 outputs if they are installed.
Output Horizontal Timing
On the standard Output module, the Program 1, Program 2, and Preview
outputs are delayed 34 lines plus approximately 5 microseconds from
reference. The Aux 1 and 2 outputs are delayed by either two lines, 18
lines, or 34 lines, depending on the source selected for them.
On the optional Frame Delay Output module, the Program 1 output is
selectable between the 34-line delay and a full frame delay from
reference. The Program 2 output has a fixed one frame delay. The
Preview output is switchable between 34-line and one frame delays. The
Aux 1 and 2 outputs have the above-mentioned variable delay, plus a
selectable one frame delay from reference. The Aux 3 and 4 outputs have
only the variable delay; you cannot select a one frame delay for these
outputs.
With either Output module installed, you can advance the output
horizontal timing by as much as 9.25 microseconds if necessary. Use the
Output Timing pushknob in the Engineering Output submenu to
