The 92A96 Module is currently available in the following versions:
H
The 92A96D Module with a 32 K memory depth
H
The 92A96XD with a 128 K memory depth
H
The 92A96SD with a 512 K memory depth
H
The 92A96UD with a 2 M memory depth
In addition to stand-alone operation the 92A96 Module can be time-correlated
with the 92A16, 92A60/90, or other 92A96 Modules to provide multiple time
base capabilities.
92HS8/E High-Speed Acquisition Modules. The 92HS8 Module allows designers of
high-speed digital systems (clocks of 100 MHz and faster) to use digital analysis
techniques to locate timing problems where signal differences are as little as
1 ns. Eight channels (each with glitch detection) can acquire data using an
internal clock. Both data and glitch information can be stored and can also be
used as a trigger source. The internal time base provides sampling intervals from
5 ms to 500 ps; memory depth is 8k words per channel. A specialized form of
external clocking (synchronous acquisition) called External Asynchronous
clocking is available.
The 92HS8 Module channels can be expanded to a maximum of 32 channels by
adding a 92HS8E cabinet and two 92HS8C cabinets.
92S16/32 Pattern Generation Modules.
These modules provide pattern generation
capabilities that can be used as a stand-alone stimulation source or can be linked
with data acquisition to provide a test system for debugging and verifying
components, boards, and systems. The 92S16 Module (16 channels plus two
strobe/data channels) features algorithmic pattern generation with a 1 K memory
depth; the 92S32 Module (32 channels plus 4 strobe/data channels) features
stored pattern generation with an 8 K memory depth. These modules can be used
separately or together to create the type of output pattern control that suits your
application. A single 92S16 Module can control up to seven 92S32 Modules;
without a 92S16 Module, up to eight 92S32 Modules can operate together.
Both modules provide pattern generation with the ability to vary the placement
of each edge in increments of 1 ns. The P6463A Pattern Generation probes
deliver the output pattern to the probe tip, providing drive equivalent to TTL or
CMOS series components. The P6464 Pattern Generation probes deliver the
output pattern to the probe tip, providing drive equivalent to AS (TTL) and
10 KH (ECL) series components.
