Standard Waveforms

The Agilent Technologies 33250A

Function/Arbitrary Waveform

Generator uses direct digital-synthesis

techniques to create a stable, accurate

output on all waveforms, down to 1 µHz

frequency resolution. The benefits are

apparent in every signal you produce,

from the sine wave frequency accuracy

to the fast rise/fall times of square

waves, to the ramp linearity.

Front-panel operation of the 33250A is

straightforward and user friendly. The

knob or numeric keypad can be used to

adjust frequency, amplitude and offset.

You can even enter voltage values

directly in Vpp, Vrms, dBm, or high/low

levels. Timing parameters can be

entered in hertz (Hz) or seconds.

Custom Waveform Generation

Why settle for a basic function genera-

tor when you can get arbitrary wave-

forms at no extra cost? With the

33250A, you can generate arbitrary

waveforms with 12-bit vertical resolu-

tion, 64K memory depth, and a sample

rate of 200 MSa/s. You can also store

up to four 64K-deep arbitrary wave-

forms in non-volatile memory with

user-defined names to help you find the

right waveform when you need it most.

The included Agilent IntuiLink soft-

ware allows you to easily create, edit,

and download complex waveforms

using the intuiLink Arbitrary Waveform

Editor.

Or you can capture a waveform

using IntuiLink oscilloscope or DMM

and send it to the 33250A for output.

For programmers, ActiveX components

can be used to control the instrument

using SCPI commands. IntuiLink pro-

vides the tools to easily create, down-

load, and manage waveforms for your

33250A. To find out more about

IntuiLink, visit

www.agilent.com/find/intuilink.

Pulse Generation

The 33250A can generate simple

pulses up to 50 MHz. With variable

edge time, pulse width and voltage

level, the 33250A is ideally suited to a

wide variety of pulse applications.

Built-in Versatility

AM, FM and FSK capabilities make it

easy to modulate waveforms with or

without a separate source. Linear or

logarithmic sweeps can be performed

with a programmable frequency

marker signal. Programmable burst

count and gating allow you to further

customize your signal.

For system applications, both GPIB

and RS-232 interfaces are standard,

and support full programmability

using SCPI commands.

Color Graphical Display

The unique design of the 33250A com-

bines a low-profile instrument with the

benefits of a color graphical display.

Now you can display multiple wave-

form parameters at the same time.

The graphical interface also allows

you to modify arbitrary waveforms

quickly and easily.

Timebase Stability and Clock Reference

The 33250A TCXO timebase gives you

frequency accuracy of 2 ppm for your

most demanding applications. The

external clock reference input/output

lets you synchronize to an external

10 MHz clock, to another 33250A, or

to an Agilent 33120A. Phase adjust-

ments can be made from the front

panel or via a computer interface,

allowing precise phase calibration

and adjustment.
