Versatile Waveform
Creation Capabilities
The Model 3390 generates highly stable and
accurate waveforms that allow you to create
almost any desired shape. It uses direct digital
synthesis (DDS) techniques to achieve this level of performance and functionality.
The exceptional signal quality of the Model 3390 is a result of its high resolution, fast rise and fall
times, and deep memory. This combined with its low price makes it the ideal solution for applications
that use the 50MHz bandwidth and below. Lower speed instruments cannot provide the signal accuracy of the Model 3390, even at bandwidths they were specifically designed for.
Arbitrary Waveform Generation (ARB)
With the Model 3390, you can precisely replicate real world signals. This 14-bit ARB provides the
ability to define waveforms with up to 256,000 data points and generate them at a sampling rate
of 125MSamples/second. For ease of use, up to four user-defined waveforms can be stored in the
onboard non-volatile memory.
Function Generation
Standard output waveforms can be created by pressing one button on the front panel. Ten standard
waveforms are provided, including the basic sine, square, ramp, and triangle shapes. The Model 3390
offers the highest repetition rates of any instrument in its class, allowing you to better emulate the
signals you need to test.
Pulse Generation
Pulse capabilities have become critically important as devices being tested have become smaller, more
sensitive, and more complex. To accurately duplicate the signals these tiny devices receive, very clean
pulses with crisp edges are mandatory, which is why the Model 3390 offers the fastest rise time (5ns)
and cleanest pulse shapes for this class of instrument.
Modulating Waveforms
The ability of the Model 3390 to modulate at
high internal frequencies allows you to accurately simulate real-world conditions. Modulate
any of your signals with the built-in AM, FM, PM,
PWM, or FSK source, or use your own external
modulation source.
Noise Generation
Inject noise into your device under test with
the press of a button. The adjustable amplitude
and offset parameters control how much or how
little noise is produced. The fast rise times and
high speed capability provides the precise noise
simulation your applications require.
The faster rise time results in cleaner pulses.

The 20MHz noise bandwidth of the Model
3390 is 2× better than the competition’s.
Pattern Generation
The Model 3390 is the only instrument in its
class with a Digital Pattern mode. It provides the
ability to transmit arbitrary 16-bit patterns via a
multi-pin connector located on the rear panel
of the instrument. This feature can be used for
applications such as testing clock and data signals directly, sending simple protocols to devices
under test, and simulating simple control functions. With Keithley’s KiWAVE software package,
you can easily create complex and long patterns,
which the Model 3390 can generate at varying
speeds and amplitudes.
10MHz External Reference
Expands Flexibility
The built-in 10MHz external time base is included at no extra cost. This external time base
makes it simple to control multiple instruments
from the same source, connect multiple Model
Ease of Use
This instrument is easy to use. In most cases,
pressing one button on the front panel or performing one or two mouse clicks on your PC
is all that is necessary to generate or modify a
waveform. The KiWAVE software package helps
you define and manage waveforms, apply filters
to waveforms, and display waveforms on a PC. In
addition, the GPIB, USB, LAN, and LXI interfaces
can connect the Model 3390 to most devices
under test, instruments, and test fixtures.
KiWAVE Waveform Editing Utility
LXI Class C Compliance
The Model 3390 supports the physical, programmable, LAN, and Web portions of the emerging
LAN eXtensions for Instrumentation (LXI) standard. The instrument can be monitored and controlled from any location on the LAN network
via its LXI Web page.
