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
