Using Trigger Signals
The HP 64700 contains two internal lines, trig1 and trig2, over which trigger
signals can pass from the emulator or analyzer to other HP 64700s on the
Coordinated Measurement Bus (CMB) or other instruments connected to the
BNC connector.
You can configure the internal lines to make connections between the
emulator, analyzer, external analyzer (if its configured as an independent
state or timing analyzer), CMB connector, or BNC connector. Measurements
that depend on these connections are called
interactive measurements or
coordinated measurements .
This figure below illustrates the possible connections between the internal
lines (trig1 and trig2) and the emulator, analyzer, and external devices.
Note that the "External Analyzer" connection for "Trig2" is only available if
you have selected "state" or "timing" for the external analyzer mode.
Notice that the analyzer always drives trig1, and the emulator always receives
trig1. This provides for the
break_on_trigger
syntax of the
trace
command.
