The BK4078B Arbitrary/Function Waveform Generator combines a DDS architecture offering easy-to-use conventional function generator capabilities with a true point-by-point AWG architecture to produce accurate and precise arbitrary waveforms. Arbitrary waveforms have 14-bit amplitude resolution, 200 MSa/s sample rate, and waveform memory of 1,000,000 points. Waveforms can be output in continuous, triggered, gated, or burst modes. The instrument can be remotely controlled using SCPI-compliant commands via USB. 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, and functional test.
