Dual Channel Function/Arbitrary Waveform Generators
4050 Series
The 4050 Series Dual Channel Function/Arbitrary
Waveform Generators are capable of generating
stable and precise sine, square, triangle, pulse,
and arbitrary waveforms. With easy-to-read color
displays and an intuitive user interface with
numeric keypad, these instruments offer plenty
Extensive modulation capabilities include
amplitude and frequency modulation (AM/FM),
double sideband amplitude modulation
(DSB-AM), amplitude and frequency shift keying
(ASK/FSK), phase modulation (PM), and pulse
width modulation (PWM).
of features including linear/logarithmic sweep,
built-in counter, extensive modulation and
triggering capabilities, a continuously variable DC
offset, and a high performance 14-bit, 125 MSa/s
arbitrary waveform generator. The main output
voltage can be varied from 0 to 10 Vpp into 50
ohms (up to 20 Vpp into open circuit) and the
secondary output can be varied from 0 to 3 Vpp
into 50 ohms (up to 6 Vpp into open circuit).
Easily create custom arbitrary waveforms using
the included waveform editing software or output
any of the 48 built-in predefined arbitrary
waveforms. Up to 10 user-defined 16 kpt
arbitrary waveforms can be saved to the
The standard external 10 MHz reference clock
input allows the instrument to be synchronized
to an external 10 MHz source or another
generator. This feature is typically not found in
function generators at this price point.
Additionally, the phase of both output channels
can be conveniently synchronized with the push
of a button.
These versatile function/arbitrary waveform
generators are suitable for education and other
applications that require high signal fidelity, a
variety of modulation schemes, or arbitrary
waveform generation capabilities.

Flexible operation
Color display with waveform preview
The large 3.5” color display highlights the
currently selected channel and shows all relevant
parameters with a preview of the waveform being
generated.
Arbitrary waveform generation
Duplicate channel parameters
Quickly copy all waveform parameters between
channels via the Utility menu. This feature can
help you save time when you need to set up two
identical output signals.
Generate waveforms with ease
Wide variety of modulation schemes
These instruments are capable of many different
types of modulation for various applications.
Modulate your waveforms with AM, DSB-AM,
FM, PM, ASK, FSK, and PWM modulation
schemes.
Synchronization and external triggering
All models in the 4050 series have non-volatile
memory to create, store, and recall up to 10
different arbitrary waveforms of up to 16,000
points each. Users can also output any of the 48
built-in predefined arbitrary waveforms.

The provided waveform editing software can
be used to create point-by-point arbitrary
waveforms via freehand or waveform math
functions. A standard USBTMC-compliant USB
device port on the rear panel allows users to
easily interface with a PC to load these arbitrary
waveforms into the instrument.
Use the external 10 MHz clock input to
synchronize your signals to a master time base.
The Sync output generates a TTL pulse for
synchronization to a channel’s frequency. An
external trigger connector is also available for
inputting or outputting trigger signals.
