Making Coordinated Measurements
To disable synchronous measurements
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. This can also be done for the
external analyzer when it is configured as an independent state or timing
analyzer.
You can use the trig1 or trig2 line to make a connection between the
emulator break input and the CMB connector, BNC connector, analyzer, (or
external analyzer when configured as an independent state or timing
analyzer) so that program execution can break when a trigger signal is
received from the CMB, BNC, or analyzer.
You can use the trig2 line to make a connection between the analyzer and the
CMB connector or BNC connector so that the analyzer can be armed (that is,
enabled) when a trigger signal is received from the CMB or BNC connector.
This can also be done for the external analyzer when it is configured as an
independent state or timing analyzer.
You can use the trig1 and trig2 lines to make several type of connections at
the same time. For example, when the analyzer finds its trigger condition, a
signal is driven on the trig1 line. This signal may be used to stop user
program execution, but the trigger signal may also be driven on the CMB and
BNC connectors.
Also, it's possible for signals to be driven and received on the CMB or BNC
connectors. So, for example, while the analyzer's trigger signal can be driven
on the CMB and BNC connectors, signals can also be received from the CMB
and BNC connectors and used to stop user program execution. In this case,
the emulator will break into the monitor on either the analyzer trigger or on
the reception of a trigger signal from the CMB or BNC.
You can disable connections made by the internal trig1 and trig2 lines by
choosing "neither" or "no" to the appropriate interactive measurement
configuration options.
In order to modify the interactive measurement specification, you must first
start the configuration interface and access the "Interactive Measurement
Specification" configuration section (refer to the "Using the Configuration
Interface" section in the "Configuring the Emulator" chapter).
