StandardWaveforms
The Agilent Technologies 33250A Function/
Arbitrary Waveform Generator uses direct
digital-synthesis techniques to create a stable, accurate output on all waveforms, down
to 1µHz 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
waveforms in non-volatile memory with
user-defined names to help you find the right
waveform when you need it most.

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

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.
using the IntuiLink
Or you can capture
• 80 MHz sine and square wave outputs
• Sine, square, ramp, noise and other
waveforms
• 50 MHz pulse waveforms with variable
rise/fall times
• 12-bit, 200 MSa/s, 64K-point deep arbitrary waveform
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 withthe 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 10MHz clock, to another
33250A, or to another Agilent 332XXA
Function/Arbitrary Wafeform Generator.
Phase adjustments can be made from the
front panel or via a computer interface,
allowing precise phase calibration
and adjustment.
