BK Precision 4079B Arbitrary Function Waveform Generator
The BK 4079B features easy-to-use conventional function generator capabilities with a true point-by-point AWG architecture to produce accurate and precise arbitrary waveforms. The waveforms have 14-bit amplitude resolution, 200 MSa/s sample rate, and large waveform memory up to 16,000,000 points. Waveforms can be output in continuous, triggered, gated, or burst modes. The 4079B can be controlled remotely using SCPI-compliant commands with GPIB and USB interface. Broad features such as internal or external AM, FM, and FSK modulation alongside adaptable sweep capabilities and variable edge pulse generation make these waveforms suitable for a wide range of applications which incluie electronic engineering design, sensor simulation, and bench function and response testing.
