High-performance single- and dual-channel arbitrary waveform generators

Versatile high-performance single- and dual-channel arbitrary waveform generators with large arbitrary memory depths are now available from Mouser stock. The B&K Precision 4075B Series instruments provide variable output voltages from 0 to 10Vp-p into 50ohm or up to 20Vp-p into open circuit and a continuously variable DC offset that allows the output to be injected directly into circuits at the correct bias level. The instruments combine the benefits of direct digital synthesis (DDS) and true arbitrary waveform generator (AWG) architectures without the limitations of either. Standard waveforms such as sine, square, and triangle are generated with a DDS chip, delivering great frequency resolution at a low cost. Custom arbitrary waveform generation is implemented with a true point-by-point design, offering improved signal integrity by producing significantly less jitter and distortion compared to a DDS-only architecture. This point-by-point generation capability allows these instruments to be used for simulating reliable clock signals, generating triggers, or validating serial data buses. Also, the generators can be used, with B&K Precision's waveform editing software WaveXpress, to create complex arbitrary waveforms. Extensive features such as internal or external AM, FM, and FSK modulation along with versatile sweep capabilities and variable edge pulse generation make the generators suitable for a wide range of applications.
