Using Trigger Signals - HP MC68360 User Manual

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, 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.
BNC <<-??->> ---\
CMBT <<-??->> ---|
Emulator <<------ ---|
Analyzer ------>> ---/
NOTES:
1. The connections marked "??" are set up here in configuration.
2. drive = ---->>
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.
You can use the trig1 or trig2 line to make a connection between the analyzer and
the CMB connector or BNC connector so that, when the analyzer finds its trigger
condition, a trigger signal is driven on the HP 64700's Coordinated Measurement
Bus (CMB) or BNC connector.
