Multimodule General Use
Multimodule involves operating two modules in conjunction with one another.
You can use multimodule operation to do the following tasks:
H
Time-correlate data between two or more modules on the display screen
H
Trigger one acquisition module when an event occurs on another module or
cross-trigger two modules
H
Perform stimulus/response testing with a pattern generator module and
acquisition module starting and stopping as a unit
H
Repeatedly compare the data acquired by an acquisition module to the data
in a reference memory until the data is equal or unequal
H
Change the pattern generator output pattern when an event occurs on another
module
H
Output a trigger signal to external test equipment such as an oscilloscope
You can use the System Configuration and Cluster Setup menus to define
module formations, to cluster (to group) modules, and to define interactions
between modules within a cluster.
The following pages provide procedures on how to set up the multimodule
operations listed above. These are general descriptions only; no specific
acquisition module or pattern generator information is given. Refer to your
module user manual for specific details such as channel grouping and clocking
selections.
Acquisition and pattern generation modules, which are the building blocks of
Digital Analysis Systems, can be used individually or in combination to perform
specific tasks. You can combine (or split apart) modules of the same type to
achieve more (or fewer) channel widths. For example, you can do the following:
H
Combine 92A16 and 92A16E acquisition modules to achieve a maximum of
96 channels in one mainframe.
H
Combine 92A96 or 92C96 acquisition modules to achieve a maximum of
288 channels in one mainframe.
H
Combine 92HS8 and 92HS8E high-speed acquisition modules to provide up
to 32 channels.
