This example illustrates the use of a multichannel delay generator to control both
experiment and WinView/WinSpec timing. One channel of the delay generator triggers
the laser. At the appropriate time, the second channel triggers the pulser. After gating,
the pulser can be used to trigger the controller, which is in the External Sync mode, or
the controller can be left in the Freerun mode and SHUTTER MONITOR used to enable
the pulser.
