Selecting the TTL Trigger Direction (HP E1407A Only)
The HP E1407A C-Size Adapter Module has a switch that allows you to set
the trigger signal direction of the TTL0 –TTL7 Trigger Lines. Figure 3-7
shows that the TTL7 Trigger Signal comes from the B-Size Module, and
TTL0–TTL6 from the Mainframe's VXI Backplane. Use the illustration as
a guide to set the appropriate trigger directions for your application.
