Block diagram of timing control for joint shot operations. The reference frequency generator (RFG) is common to both
systems. The shot triggers used in the OMEGA EP system are distributed by a trigger generator/selector unit (TG/S) that has
separate modes for independent and joint operations. In the independent mode, the TG/S generates synchronized T–10 and
T–0 shot triggers for OMEGA EP only. In the joint mode, the signals generated by the MTG are used in both systems.

The MTG outputs horizontal and vertical video synch and 5-Hz and 0.1-Hz signals synchronized
to the 38-MHz master oscillator signal. Synchronized, single-pulse shot triggers (T–0 and T–10) are also
produced by the MTG in response to enabling signals provided by the Power Conditioning Executive
(PCE) workstation. The MTG timing signals are distributed to the appropriate elements (primarily
timing crates and alignment video equipment.
