92A16/E Data Acquisition Modules. The 92A16/E Module is a 200 MHz,
16-channel data acquisition module suited for general-purpose, medium-speed
hardware timing analysis and for high-speed state analysis. It uses two P6461/E
probes (or lower-bandwidth P6460 probes) to acquire data with either an internal
(asynchronous) or external (synchronous) clock equation. Data is stored on each
active clock edge until a trigger is generated and the delay counter value is
reached. Support for two-phase clocking (demultiplexing) is also provided.
The 92A16 Module acts as either a Master or an Expansion module; the 92A16E
Module is strictly an Expansion module. The 92A16 and 92A16E Modules can
be combined into a single 96-channel-wide module in one mainframe; all
channels operate under the same trigger and clock conditions and run at
200 MHz (no speed vs. channel width trade-offs). The first 64 channels can be
used for word recognition. In addition to stand-alone operation, the 92A16
Module can be correlated with other data acquisition modules in the DAS
mainframe to provide multiple time base capabilities.
92A60/D and 92A90/D Data Acquisition Modules.
The large number of acquisition
channels (60 maximum) allows the 92A60 Module to serve as the basis for a
variety of DAS features, including microprocessor support, general-purpose state
analysis, and software performance analysis. The 92A90 Module (90 channels
maximum) provides increased width.
The 92A60 and 92A90 Modules are available in two versions: the standard
92A60/90 Module versions provide 32 k memory depth; the 92A60D/90D
Module versions offer 128 k memory depth.
Both the 92A60 and 92A90 Modules use a retargetable buffer probe that can be
quickly changed to fit the application. The 92A60/90 Modules cannot be
combined for applications requiring more channels; however, acquired data can
be time correlated with other acquisition modules.
92A96 and 92C96 Data Acquisition Modules.
The 92A96 Module is a 100 MHz,
100-channel data acquisition module suited for general-purpose, medium-speed
hardware analysis, 32-bit microprocessor support, and up to 400 MHz high-
speed timing analysis. The 92A96 Module can be expanded to provide up to 288
channels of acquisition at speeds of 100 MHz (synchronous) and 72 channels at
speeds of up to 400 MHz (asynchronous). The module comes with 8-channel
probes and single-channel clock probes.
The 92C96 Module is a subset of the 92A96 Module that can easily be upgraded
for deeper acquisition memory. Unless stated otherwise, the terms 92C96 and
92A96 are used interchangeably.
