Making Coordinated Measurements
When HP 64700 Card Cages are connected together via the Coordinated
Measurement Bus (CMB), you can start and stop up to 32 emulators at the same
time.
You can use the analyzer in one HP 64700 to arm (that is, activate) the analyzers in
other HP 64700 Card Cages or to cause emulator execution in other HP 64700
Card Cages to break into the monitor.
You can use the HP 64700’s BNC connector (labeled TRIGGER IN/OUT on the
lower left corner of the HP 64700 rear panel) to trigger an external instrument (for
example, a logic analyzer or oscilloscope) when the analyzer finds its trigger
condition. Also, you can allow an external instrument to arm the analyzer or break
emulator execution into the monitor.
The coordinated measurement tasks you can perform are grouped into the
following sections:
•
Setting up for coordinated measurements.
•
Starting and stopping multiple emulators.
•
Driving trigger signals to the CMB or BNC.
•
Stopping program execution on trigger signals.
•
Arming analyzers on trigger signals.
