Keysight 33250A
Function/Arbitrary Waveform Generator
Data Sheet
02 | Keysight | 33250A Function/Arbitrary Waveform Generator - Data Sheet
Standard Waveforms
The Keysight Technologies, Inc. 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 benets 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-dened names to
help you nd the right waveform when you need it most.
The included Keysight 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 nd out more about IntuiLink, visit
www.keysight.com/nd/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.

–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
Color Graphical Display
The unique design of the 33250A
combines a low-prole instrument
with the benets 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 wave-
forms 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 another Keysight 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.
