Atec DG2020 User Manual

The DG2000 Series of digital
pattern generators provide
digital designers with the
high performance tools
needed to evaluate advanced
digital semiconductors and
logic circuits. Whatever you
call your design process
– characterization, debug,
validation, or verification
– as a digital designer you
must have state-of-the-art
digital pattern generation as
you push the edge of the
technology envelope and race
to market.

Choose the Best Fit

The DG2000 Series is remark­able for the balanced
approach to providing the
appropriate class of instru­ment for a wide variety of
digital design applications.
Performance ranges from 1.1
Gbits per second to 200 Mbits
per second and from 2 to 36
channels. The table illus­trates the principal specifica­tions for members of the
DG2000 Series.

Critical Timing

The DG2000 Series is the
ideal solution for applica­tions where you must charac­terize device or circuit timing
and amplitude margins. The
DG2000 Series is perfect for
simulating setup and hold
violations or conditions of
metastability. The DG2000
graphical user interface
allows you to quickly create
complex data patterns with a
few keystrokes on the front
panel. Use the advanced
sequence editing capability
of the DG2000 Series to insert
infrequent faults or glitches
in your data patterns to verify
device or circuit recovery.
The DG2000 Series is an
invaluable tool, allowing you
to simulate missing system
functionality while meeting
critical market windows.
With the introduction of the
DG2040, new capabilities are
available to control clock and
data jitter or modulate pulse
edges on a selective basis.
