Specifications

advance the output horizontal phase of all digital outputs by up to 9.25

microseconds, in 18.5 nanosecond (1/4 pixel) steps.

Output Module Connections

The following describes all Output module connectors.

Reference (REF, REF LOOP)

Two 75Ω BNC connectors provide a passive looping system reference

connection. Feed the 8150 color black or composite sync. The system

accepts 525 or 625 line reference feeds. Set the system line standard to

match the reference line standard in the Engineering menu

Miscellaneous submenu. The LED between the connectors lights green

to indicate sync is present and matches the system standard (525 or 625).

It lights yellow to indicate that sync does not match the selected system

standard. It lights red to indicate that no sync present at all.

Termination Switch

Use the reference termination switch to terminate nonlooping reference

feeds into 75Ω.

Auxiliary Outputs (AUX 1, AUX 2)

Optional CCIR 601/SMPTE 259M serial digital auxiliary bus output

feeds are provided on 75Ω BNC connectors. You can choose the output

video source for each Aux output in the Miscellaneous menu. Note that

the connectors are present even if option is not installed.

With the standard Output module, these outputs are delayed by two

lines, 18 lines, or 34 lines from reference, depending on the source

selected. With the Enhanced Frame Delay Output module only, in

addition to the above delays, you can select a one frame delay for these

outputs in order to zero time them back into your system. With either

Output module, the Aux 1 and 2 outputs are always zero timed to each

other.

Preview Output (PVW)

One CCIR 601/SMPTE 259M serial digital preview output is provided

on a 75Ω BNC connector. With the standard Output module, this output

is delayed approximately 34 lines from reference (zero timed to the

program outputs). With the Enhanced Frame Delay Output module

only, you can also select a one frame delay to match the Program 2

output.
