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

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.
