Trueform Technology
33500B Series waveform generators with exclusive Trueform signal
generation technology offer more capability, fidelity and flexibility than
traditional DDS generators. Use them to accelerate your development
process from start to fi nish.
Over the past two decades, direct digital synthesis (DDS) has been the
waveform generation technology of choice in function generators and
economical arbitrary waveform generators. DDS enables waveform
generators with great frequency resolution, convenient custom
waveforms, and a low price.
As with any technology, DDS has intrinsic downsides and limitations
as well. Engineers with exacting requirements have had to either work
around the compromised performance or spend up to 10 times more
for a high-end, point-by-point waveform generator.
The Keysight Technologies, Inc. Trueform technology offers a
new alternative that blends the best of DDS and point-by-point
architectures, giving you the benefits of both without the limitations
of either. Trueform technology uses an exclusive digital sampling
technique that delivers unmatched performance at the same low price
you are accustomed to with DDS.
The table below highlights the revolutionary capabilities of
Trueform technology.

The 33500B Series waveform generators offer the common signals
and features you expect, such as modulation, sweep, and burst.
But the 33500B Series offers many more features that give you the
capabilities and flexibility you need to get your job done. Like an
intuitive front-panel user interface that makes it easy to quickly relearn
it when you’ve been focused elsewhere. Like built-in LAN, USB
and GPIB interfaces that make it easy to control your instruments or
transfer your waveforms to your instrument.
But the 33500B Series doesn’t stop there. It offers a variety of
capabilities you won’t find elsewhere—capabilities that help you
accelerate your testing and get your project wrapped up faster:
capability
Easily add noise to your signal for margin and distortion testing
using only a single channel. You can create dual-tone
multifrequency signals without a dual-channel generator,
which means you can preserve your budget for other test
needs. On a two-channel model, you can sum and combine
up to four signals.
You can adjust the bandwidth of the built-in noise generator to
control the frequency content of your signal. Apply just the frequency
stimulus you need so you concentrate the energy of your waveform
in frequency bands of interest.
Trueform Technology
The images at right show
approximately 10 dB increase
in amplitude at 50 kHz when
the bandwidth is reduced 10x.
You can see how the signal
energy is increased in the
frequencies of interest when
the bandwidth is reduced,
instead of being spread over
a very wide bandwidth
with lower amplitude at all
frequencies.
Dual-tone signal created
by summing waveforms
using the modulation
type, “Sum.”

DDS technology may skip points at higher
frequencies
Define any waveform shape and any waveform length using point-by
-point arbitrary waveform capability. Your waveforms are always
anti-aliased for exceptional accuracy, and you can play them at any
rate you select. Play your signals as defined, at your exact sample
rate, without the chance of missing short-duration anomalies that are
critical for testing device reliability.
Waveform sequencing
Waveform sequencing lets you create multiple configured waveforms
with several common segments and lets you build long, complex
waveforms using minimal instrument memory.

(PRBS) pattern generation
Test your digital serial buses by streaming standard PRBS patterns—
like PN7 and PN19—without the need for a separate pulse
generator. With fewer instruments, setting up your tests is easier.
You won’t find these built-in PRBS patterns in competitive
waveform generators.
There are five ways to create arbitrary waveforms for use
with the 33500B generator.
1. Use the included Waveform Builder Basic software to edit
and download a waveform file to the generator
2. Use 33503A Waveform Builder Pro software to create
more complex waveforms and sequencing
3. Capture a waveform from an oscilloscope and download
it to the generator
4. Create a waveform in MATLAB, Excel, etc. and download
it to the generator
5. Use the generator’s front panel to edit a waveform once
it is in the generator
You have lots of flexibility to choose the way you want to work.

Built-in Web browser
Easily set up and control your 33500B Series generator remotely
over a LAN connection using the built-in LXI Web browser. You can
monitor your tests and adjust settings from another office or
room, or even from home.
If you want to test your design with long, complex waveforms
with a variety of anomalies, you need to make sure your waveform
generator has sufficient memory. The 33500B Series’ standard
memory is 1 MSamples deep.
Typical DDS generators
offer only a fraction of that
amount but with the
33500B Series there is even
a 16 MSample memory
option available.
Use the optional high-stability timebase
for even better accuracy
Get improved timebase stability and frequency accuracy using the
optional high-stability timebase. The optional timebase offers
0.1 ppm stability, which is 20x more stable than the standard
timebase over one year.

33500B Series waveform generators offer the
Lowest jitter
With 12x better jitter than anything in their class, 33500B Series
waveform generators offer unparalleled edge stability. You can
even use them as a system clock for timing and triggering your other
instruments. With better jitter performance, you can place edges more
accurately, helping you reduce timing errors in your circuit design.
With total harmonic distortion of just 0.04%, the 33500B Series offers
5x better fidelity than other generators. Clean, spurious-free signals
don’t introduce noise or artifacts. See your design’s characteristics, not
the waveform generator’s, in your measurements.
The 33500B Series’ 8.4-ns rise and fall times are more than twice as
fast as you’ll find in typical waveform generators. You can place edges
with more confidence and more accurately set trigger points. Because
of the faster transition, higher harmonic content is created, which
helps you expand your understanding of your circuit.
Trueform Technology
that your signal generator is outputting
the signals you expect
Keysight 33500B Series waveform generators offer the lowest total
harmonic distortion (THD) in its class.
Typical DDS generator has a higher noise floor and greater
harmonics.
<40 ps 500 ps
Trueform technology significantly improves jitter performance.
Trueform technology. Traditional DDS technology.
If your generator is introducing spurious signals or harmonics, you’ll
have a hard time producing reliable designs. To be successful, you
need to test with clean, precise, low-noise signals. Keysight 33500B
Series waveform generators offer the highest signal fidelity so you can
generate the exact waveforms you need for your most challenging
measurements. You can be confident you are seeing your design’s
characteristics, not your waveform generator’s, in your measurements.

Today’s ultra-low-power products such as pacemakers, hearing aids
and remote sensors use very low voltages. The 33500B Series lets
you create signals as low as 1 mVpp. That’s 10x better amplitude
resolution than typical waveform generators offer.
Eliminate the need for an external modulation source. The 33500B
Series has a modulation frequency up to the frequency of the
waveform being modulated. Existing DDS-based generators have
a much lower internal modulation frequency. Now you can create
your complex signals all within a single generator.
The 33500B Series’ 16 bits of resolution is 4x that of most waveform
generators. You can make output changes all the way down to
1 V—exactly what you need for testing today’s low-voltage circuits
and designs.
Create pulses up to 30 MHz with the 33500B Series. Most DDS-
based generators offer reduced bandwidth when generating pulses.
With a broader operating range, you have the frequency you need for
a wider range of applications.

Investment protection
With most waveform generators, you get only what you pay for when
you buy your instrument. But with 33500B Series waveform genera-
tors, there are eight different models to choose from so you can
purchase the capability you need now and upgrade later when your
project needs change. Your investment in test equipment is protected.
If you need to generate 30 MHz waveforms or arbitrary waveforms,
or if you need deeper memory for generating more complex signals,
you can easily add the capability after the fact with software
upgrades. And there’s no price penalty for adding the capability later.
If you are doing simple experiments in digital communications,
use the optional IQ player to play IQ files on your 2-channel
function generator.
Select from eight models to get the capability that fits your budget
now—then take advantage of easy software upgrades to expand
your instrument’s capabilities when you are ready.
Optional IQ player allows you to play Q files
on your 2-channel Arb function generator.

The warranted performance of a calibrated instrument that has been stored for a
minimum of 2 hours within the operating temperature range of 0º C – 55º C and
after a 45-minute warm up period. All specifications include measurement uncer-
tainty and were created in compliance with ISO-17025 methods.
Data published in this document are specifications (spec) only where specifically
indicated.
Typical (typ)
The characteristic performance, which 80% or more of manufactured instruments
will meet. This data is not warranted, does not include measurement uncertainty,
and is valid only at room temperature (approximately 23ºC).
Nominal (nom)
The mean or average characteristic performance, or the value of an attribute that
is determined by design such as a connector type, physical dimension, or operating
speed.
This data is not warranted and is measured at room temperature (approximately
23ºC).
An attribute measured during development for purposes of communicating the
expected performance. This data is not warranted and is measured at room tem-
perature (approximately 23ºC).
Accuracy
Represents the traceable accuracy of a specified parameter. Includes measurement
error and timebase error, and calibration source uncertainty.
Random measuremet errors are combined using the root-sum-square method and
are multiplied by M for the desired Confidence Level. Syatematic errors are added
linearly and include time skew errors, trigger timing errors, and timebase errors as
appropriate for each measurement type.
For 99% Confidence use k= 2.5 in accuracy calculations.
For 95% Confidence use k= 2.0 in accuracy calculations.
