Tektronix offers a wide variety of Arbitrary Function and Arbitrary Waveform Generators that have the capabilities to earn the title of "Mixed Signal Source".
From the 16 MS/s Bench AFG 300 to the 4.0 GS/s programmable AWG 710, Tektronix has an Arbitrary signal source to solve your application requirements.

Arbitrary waveform generators are used to generate "real world" signals.
They can generate signals with all the glitches, drift, noise and other anomalies that a device under test will encounter when it leaves the lab or manufacturing floor.
In addition to creating standard functions like Sine, Square, Triangle, Noise, and DC, AWGs are being used for disk drive testing, serial data communication, Base band/IF modulation testing, anti-lock braking, engine control, transducer and biomedical simulations and much more.

"What if" scenarios are straightforward since waveforms can be captured from a digital scope and then modified to see when a device under test fails.
They also import waveforms from simulation tools like Mathcad and Matlab for easy connectivity to your DUT.

Arbitrary Waveform Generators have evolved from simple D/A converters to sophisticated signal sources with powerful creation, editing, triggering and real-time sequencing capabilities.
