Over the past two decades, 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.

DDS

As with any technology, DDS has its limitations. Engineers

with exacting requirements have had to either work around the
compromised performance or spend up to 5 times more for a highend, point-per-clock waveform generator.

Unmatched capabilities for generating a full range of signals for the most
demanding requirements
The 33600A Series waveform generators offer the common signals
and features you expect, such as modulation, sweep and burst.
However, it also offers features that give you the capabilities and
lexibility you need to get your job done quickly, no matter how
complex. An intuitive front-panel user interface, for example, can be
quickly and easily relearned when your attention has been focused
elsewhere. Built-in LAN, USB and optional GPIB interfaces allow
you to easily control your instruments or transfer waveforms to your
instrument. And thats just the beginning.
The 33600A Series waveform generators offer a variety of capabilities
you cant ind anywhere elsecapabilities designed to help you
accelerate your testing and get your project wrapped up faster:

Waveform summing and combining 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.

Variable-bandwidth noise
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.

The images at right show an

approximate 10 dB increase in
amplitude at 50 kHz when the
bandwidth is reduced 10x. Note
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.

modulation type Sum.

Standard deep memory

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 suficient memory. The 33600A Series standard
memory is 4 MSamples deep. Typical DDS generators offer only a
fraction of that amount but with the 33600A Series there is even
a 64 MSample memory option available.

Signal integrity: test your devices with conidence that your signal generator is
outputting the signals you expect
If your generator is introducing spurious signals or harmonics,
youll have a hard time producing reliable designs. To be
successful, you need to test with clean, precise, low-noise
signals. Keysight 33600A Series waveform generators offer the
highest signal idelity so you can generate the exact waveforms
you need for your most challenging measurements. You can be
conident you are seeing your designs characteristics, and not
that of your waveform generator, in your measurements.

Lowest harmonic distortion

With total harmonic distortion of just 0.03%, the 33600A Series
offers 5x better idelity than other generators. Clean, spuriousfree signals dont introduce noise or artifacts. See your
designs characteristics, not the waveform generators, in your
measurements.

33600A Series waveform generators offer the

following advantages:
Lowest jitter
With 1 ps jitter, 200x better than DDS generators, 33600A 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.
Trueform technology signiicantly improves jitter performance.
Keysight 33600A Series waveform generators offer the lowest total harmonic
distortion (THD) in its class.

<1 ps

Trueform technology

<200 ps

Traditional DDS technology

Faster edge times

The 33600A Series 2.9-ns rise and fall times are more than twice as
fast as youll ind in typical waveform generators. You can place
edges with more conidence 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.

Typical DDS generator has a higher noise loor and greater harmonics.

09 | Keysight | M33600A Series Trueform Waveform Generators - Data Sheet

Signal Integrity (continued)

Reproduce lower-voltage output signals
Todays ultra-low-power products such as pacemakers, hearing
aids and remote sensors use very low voltages. The 33600A
Series lets you create signals as low as 1 mVpp. Thats a 10x lower
voltage range than typical waveform generators.

High-bandwidth pulses
Create pulses up to 100 MHz with the 33600A 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.

Full bandwidth modulation sources

Eliminate the need for an external modulation source. The
33600A 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.

Select the capabilities you need now, then upgrade easily when your needs change
Investment protection
With most waveform generators, you get only what you pay for
when you buy your instrument. But with 33600A Series waveform
generators, there are four 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 120 MHz 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 theres no price penalty for adding the capability later.

Waveform characteristics (continued)

Arbitrary waveform sequencing
Operation

Individual arbitrary waveforms (segments) can be combined into user-deined lists (sequences) to form longer, more
complex waveforms. Each sequence step speciies whether to repeat the associated segment a certain number
of times, to repeat it indeinitely, to repeat it until a Trigger event occurs, or to stop and wait for a Trigger event.
Additionally, the behavior of the Sync output (Marker) can be speciied in each step. To improve throughput, multiple
sequences and segments can be pre-loaded into volatile memory.

Deinitions
Speciication (spec)
The warranted performance of a calibrated instrument that has been stored for a
minimum of 2 hours within the operating temperature range of 0 to 55 C and after
a 1-hour warm up period. All speciications account for the effects of measurement
and calibration-source uncertainties, and were created in compliance with
ISO-17025 methods. Data published in this document are speciications (spec)
only where speciically indicated.

Typical (typ)
The characteristic performance that 80% or more of manufactured instruments will
meet. This data is not warranted, does not include measurement or calibration-source
uncertainty, and is valid only at room temperature (approximately 23 C).

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 23 C).

Measured (meas)
An attribute measured during product development for the purpose of communicating
expected performance. This data is not warranted and is measured at room temperature
(approximately 23 C).
