Industry Leading Performance

Models 4075 and 4078 are versatile high performance function/arbitrary waveform generators with the
largest arbitrary memory depth in their class. The generators combine the ability to produce nearly any
conceivable arbitrary waveform with accuracy and precision and a DDS architecture offering easy to use
conventional function generator capabilities. Arbitrary waveforms have 14 bit amplitude resolution,
100MSa/s sample rate and up to 400,000 points length. Waveforms can be output in continuous, trig­gered, gated or burst modes. Front panel operation is straightforward and user-friendly. The instruments
can be remotely controlled using SCPI-compliant commands via RS232.

Extensive features such as internal or external AM, FM and FSK modulation along with versatile sweep
capabilities and variable edge pulse generation make these generators suitable for a wide range of applica­tions including electronic design, sensor simulation, functional test or generation of I/Q modulated signals.

Dual Channel Model 4078

■ Both channels offer full functionality. All wave

form parameters such as frequency, amplitude

and offset can be set independently

■ Synchronize both output signals to the same

clock signal (external or internal) and precisely

adjust the phase relationship between the two

signals

■ Economical baseband I/Q signal source

■ Saves cost and bench space

Intuitive user interface

These Waveform Generators use a menu-driven
front panel keypad and control knob along with
an easy-to-read graphical LCD to adjust all
waveform parameters, which are visible at one
glance. Arbitrary waveform editing and definition
is flexible and easy: Waveforms can be defined
from scratch by entering data point by point, by

loading and modifying predefined built-in wave­forms or by downloading waveforms via the
remote interface, using either the included arbi­trary waveform generation software Wave-X or a
custom program. Standard function generator
waveforms sine, square, ramp and pulse can be
created by pressing a single button.

optional GPIB interface

Model 4078 allows for both

independent and phase synchro-

nized waveform generation

Flexible interface

Built-in 10 MHz external reference is included
at no extra cost (both models).
This input/output let’s you synchronize with
another 4075/4078 generator or to an
external 10 MHz Clock for precise phase
adjustment.

Connect the programmable marker Output to
the Trigger input of additional generators to
create complex polyphase scenarios.
