Achieving a New Level of Accuracy and Flexibility
Everyday you’re developing new
technologies that are faster, more
efficient, smaller, greener and require
more accuracy than ever before.
Agilent 33500 Series function/
arbitrary waveform generators offer
the highest signal fidelity and implement a new breakthrough technology
that provides you with the ability to
generate more accurate arbitrary
waveforms. With 10x better jitter
than anything in their class, they
offer unparalleled control of signal
frequency for your most challenging
measurements.
33500 Series Function/Arbitrary Waveform Generators
Key features
• 30 MHz sine, square, and pulse
bandwidth cover more applications
• < 40 ps jitter and less than .04%
total harmonic distortion for more
precise signals
• 250 MSa/s, 16-bit sampling rate
for higher time-resolution arbitrary
waveforms
• True point-by-point arbitrary
waveforms with sequencing
for more accurate representation of
user-defi ned signals
• Dual-channel mode with
independent or coupled channels
• 1 MSa waveform memory
standard, 16 MSa (optional)
for more complicated arbitrary
waveforms
• LXI Class C compliant
• Large, color, graphical display
allows for simultaneous parameter
setup and signal viewing/editing
for intuitive operation
• Optional BenchLink Waveform
Builder Pro software for custom
user-defi ned waveforms
Signal fidelity
You depend upon the fidelity of
generated signals to verify the
development of your designs. The
higher the fidelity of the generated
signal, the more assurance the device
under development will perform to
your exacting standards. The 33500
Series function/arbitrary waveform
generators have < 40 ps jitter for
any signal ― ten times better than
existing function/arbitrary waveform
generators. They provide 16-bit resolution, which is the highest resolution
in their class. Combined with less
than .04% total harmonic distortion
and 250 MSa/s, 16-bit sampling,
optional high-stability timebase and
optional arbitrary waveform memory
expansion, you now have access to
an affordable new family of generators with unparallel signal fidelity.
Flexible signal generation
The 33521A and 33522A have the
ability to create two-tone signals for
dual-tone multi-frequency (DTMF)
signal applications used in telecommunication device test.
A feature specific to the 33522A
generator is a flexible, dual-channel
mode with frequency and amplitude
coupling, differential channels, and
combined output channels. This
functionality is useful in applications
where testing a device, such as a
pacemaker, relies on the timing and
interaction of two distinct signals to
operate properly.
Point-by-point waveforms
The 33500 Series expands your
signaling capability with true pointby-point arbitrary waveforms that are
always alias-protected for exceptional
accuracy. The 33521A and 33522A
are first in their class to generate
30 MHz signals, including common
waveforms, arbitrary waveforms and
sophisticated modulated waveforms.
Both models leverage proprietary
technology to provide you with
unprecedented input control when
defining arbitrary waveforms. That
control equates to the ability to
define more complex point-by-point
waveforms with sequencing.
User interface
A large, color, graphical display
offers simultaneous parameter
setup, signal viewing, and editing for
easy operation. The 33500 Series is
fully compliant with the LXI Class C
specifications and offers USB 2.0 and
10/100 Base-T Ethernet connectivity
for quick and easy connectivity to a
PC or network. The 33500 Series also
supports remote operation using a
browser to connect to a built-in Web
page. GPIB is offered as an optional
interface.
Optional 33503A BenchLink
Waveform Builder Pro Softrware
Benchlink Waveform Builder Pro is
ideal for R&D engineers characterizing new designs and test system
engineers validating production
units. The software is a Microsoft
Windows®-based program that provides easy-to-use creation tools, such
as an equation editor, waveform math
and drawing tools, which can be used
to create custom signals. It features
a standard function library, waveform
sequencer, and filters and; as well as
windowing functions that allow you
to easily modify and further refine
your waveform. A library of built-in
signals supports fast creation of more
complex waveforms.
With BenchLink Waveform Builder
Pro, you gain access to advanced
signal creation and editing capabilities, without requiring hours of
programming. The result is quicker,
easier creation of custom waveforms,
coupled with deeper analysis insight
into your signals.
