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, trig-

gered, 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 applica-

tions including electronic design, sensor simulation, functional test or generation of I/Q modulated signals.
