The Model 4075 and 4078 are versatile high performance arbitrary waveform generators. Arbitrary waveforms can be programmed and generated with 14 bit resolution and up to 400,000 points length. Waveforms can be output in continuous, triggered, gated or burst mode. AM and FM modulation combined with versatile Sweep capabilities make the unit suitable for a wide range of applications. Editing is flexible and easy including auto increment, line draw and predefined waveform facilities. The instrument can be remotely operated via the RS232 or an optional GPIB interface (order models 4074GPIB or 4078GPIB) and they are SCPI compatible.
