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 generator when you can get arbitrary waveforms at no extra cost? With the
33250A, you can generate arbitrary
waveforms with 12-bit vertical resolution, 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 software 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 provides the tools to easily create, download, and manage waveforms for your
33250A. To find out more about

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 combines a low-profile instrument with the
benefits of a color graphical display.
Now you can display multiple waveform 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 adjustments can be made from the front
panel or via a computer interface,
allowing precise phase calibration
and adjustment.
