Models 296 and 295
50 MS/s Synthesized Multichannel Arbitrary
Waveform Generators
the front panel using the mouse and any of
four modes: free hand, line draw, line list,
and mathematical expressions. In addition,
extensive waveform editing tools enable the
user to control waveform shapes precisely.
The editing tools make it easy to modify
existing waveforms. This is particularly
useful in such applications as characteriza-
tion testing. For instance, amplitude may be
modified continually in order to characterize
performance of the unit under test. For more
complex applications, waveform linking,
looping and sequencing allow users to create
long, complex waveforms.
Versatile interchannel capabilities are
provided. An internal summing bus allows
waveforms from multiple channels to be
summed together. Other interchannel
capabilities include setting phase shift
between channels, linking waveforms
together and triggering one channel from
another.
Waveforms, sequences, and entire
instrument set-ups can be stored in the
internal nonvolatile 60 kB RAM or on disk
via the disk drive.
It’s Easy to Create Any Waveform. Models
296 and 295 take the limits off your ability to
simulate the signals you are faced with in the
real world.
Built-in features make interactive
control of complex waveforms and instru-
ment set-up simple. Waveforms can be
created, copied, edited, downloaded, and
sequenced, all with a few clicks of the
mouse. The 296 and 295 provide a complete
set of tools that enables you to specify all
kinds of waveforms in a number of ways,
from precise mathematical description to
“what-if” freehand sketching. And modify-
ing waveforms is a snap with tools such as
Vertical Resize and Vertical Move. The
sophisticated user interface gives you access
to all the power of the 296 and 295, with a
flexibility in waveform creation never before
M
odels 296 and 295 combine sophisti-
cated performance with ease of use in
a way previously not available in
arbitrary waveform generators. Model 295 is
the basic model. Model 296 adds advanced
waveform sequencing capability up to
4,096 waveform segments for complex
waveform generation. It also provides a 16
bit digital output on each channel.
Both models can contain up to four
separate channels. When run independently,
each channel is essentially a stand-alone
arbitrary waveform generator. When in
master/slave mode, phase relationships
between channels can be set by the user.
Each channel outputs 15 Vp-p (into 50
Ω
load) at 50 MS/s sampling frequency
maximum or can output 100 volts peak-to-
peak when Option 007 is installed. Each
channel has a high-speed clock output that
runs at a maximum of 100 MHz.
Arbitrary waveforms can be created and
stored to nonvolatile RAM or on the
standard MS-DOS™ compatible 3.5-inch,
high-density disk drive. In addition, ten
commonly used synthesized functions are
built in.
The graphic user interface greatly
simplifies creating and editing waveforms,
which can be viewed on an oscilloscope. A
mouse (provided) is used to draw on a scope
when creating waveforms and to make
selections on the graphical interface when
setting up the instrument.
