Settings→Bnc→Outputs Analyzer Trigger (Alt, S, B, O) - HP 68302 User Manual

Chapter 8: Menu Bar Commands
Settings→BNC→Outputs Analyzer Trigger (ALT, S, B, O)
Settings→BNC→Outputs Analyzer Trigger (ALT, S, B,
O)
Specifies that the analyzer trigger signal be driven on the BNC port.
Selecting the emulator BNC port for output enables the trigger signals to be
fed to external devices (for example, logic analyzers) during tracing.
CAUTION
Do not drive the BNC beyond the range of 0 to 5 volts. Doing so may cause
permanent damage to the HP 64700.
The BNC's drivers can drive 50 ohm loads.
The following is a logical diagram of the BNC connection. The physical
implementation and values of resistors are not exact; this diagram is just to
help you understand the BNC interface:
When a trace starts, it stops driving the output (so if nothing else is driving
the line, it will fall low due to the 500 ohm pull-down resistor).
When the trigger point is found, the BNC starts driving the output high. It
will stay high until the start of the next trace.
