Chapter 10: Making Coordinated Measurements

Using Trigger Signals

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.
To configure the internal trig1 and trig2 lines, you must enter the modify
configuration command and then answer "yes" to the "Modify interactive
measurement specification?" question. When you do this, the following display
appears.
This display illustrates the possible connections between the internal lines (trig1
and trig2) and the emulator, analyzer, and external devices.
Note that the "External Analyzer" option for "Trig2" only appears 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.
