The 4076 is a versatile high performance function / arbitrary waveform generator with the largest arbitrary memory depth in its class. The generator combines 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, 125 MSa/s sample rate and up to 4 million points of length. Waveforms can be output in continuous, triggered, gated or burst modes. The instrument can be remotely controlled using SCPI-compliant commands via RS232.

Extensive features such as waveform summing, internal or external AM, FM and FSK modulation along with versatile sweep capabilities and variable edge pulse generation make this generator suitable for a wide range of applications including electronic design, sensor simulation and functional test.

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.

Built-in 10 MHz external reference is included at no extra cost (both models). This input/output let’s you synchronize with another 4076/4079 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.

Unlike other comparable generators, which typically contain only a few fixed-size memory locations for waveform storage, the 4076 and 4079 gives users more freedom - the 4,000,000 point flash memory can be allocated to one large waveform or up to 50 different waveforms, each with a customizable length.

In Arb mode you can conveniently add noise to your waveform directly from the front panel and precisely adjust the scale of the noise amplitude. Unlike other generators that only produce a noise waveform, this feature allows you to choose between generating a noise waveform or adding noise to an existing waveform.

The Summing Input on the rear panel allows waveforms from external signal sources to be summed with the output signal of the 4076 or 4079.

Model 4076 provide fully programmable markers, allowing you to generate a positive TTL level output signal at the points specified by address and length up to 4000 points. This feature is available in Arbitrary mode and can not be found in other comparable waveform generators. It could be used for applications requiring polyphase signal generation, e.g. simulation of a real world 3 phase AC network where one of the phases is degraded with spikes or noise.

The included PC Software allows you to easily generate, edit and download custom arbitrary waveforms.

Generate waveforms by importing a textfile, or define via freehand, point draw or waveform math. Waveforms can also be uploaded from the generator for documentation purposes.
