Signal Lines on the CMB
There are three bi-directional signal lines on the CMB connector on the rear
panel of the emulator. These CMB signals are:
TRIGGER The CMB TRIGGER line is low true. This signal can be
driven or received by any HP 64700 connected to the CMB. This signal
can be used to trigger an analyzer. It can be used as a break source for
the emulator.
READY The CMB READY line is high true. It is an open collector and
performs an ANDing of the ready state of enabled emulators on the CMB.
Each emulator on the CMB releases this line when it is ready to run.
This line goes true when all enabled emulators are ready to run,
providing for a synchronized start.
