Chapter 9: Making Coordinated Measurements
Using Trigger Signals
execution can break when a trigger signal is received from the CMB, BNC, or
analyzer.
You can use the trig2 line to make a connection between the analyzer and the CMB
connector or BNC connector so that the analyzer can be armed (that is, enabled)
when a trigger signal is received from the CMB or BNC connector.
You can use the trig1 and trig2 lines to make several type of connections at the
same time. For example, when the analyzer finds its trigger condition, a signal is
driven on the trig1 line. This signal may be used to stop user program execution,
but the trigger signal may also be driven on the CMB and BNC connectors.
Also, it's possible for signals to be driven and received on the CMB or BNC
connectors. So, for example, while the analyzer's trigger signal can be driven on
the CMB and BNC connectors, signals can also be received from the CMB and
BNC connectors and used to stop user program execution. In this case, the
emulator will break into the monitor on either the analyzer trigger or on the
reception of a trigger signal from the CMB or BNC.
You can disable connections made by the internal trig1 and trig2 lines by
answering "neither" or "no" to the appropriate interactive measurement
configuration question.
