B&K Precision 4047B Dual Channel Function/Arbitrary Generator

B&K Precision 4047B Dual Channel Function/Arbitrary Waveform Generator creates precise and stable sine, square, triangle, pulse, and arbitrary waveforms. The dual outputs of the 4047B are completely independent with individual on/off buttons and can both be varied from 0 to 10Vpp into 50Ω (up to 20Vpp into open circuits). The 4047B generator offers linear and logarithmic sweep capabilities, AM/FM/PM/FSK/PWM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level. Separate output amplitude and DC offset amplifiers allow users to set a large DC offset (e.g. ±4.99V) with a small amplitude output signal (e.g. 10mV).

The 4047 B's dual architecture offers all the benefits of a combined DDS and a true point-by-point arbitrary waveform generator (AWG), minus the limitations of either technology. The DDS chip produces standard sine and triangle waveforms with high-frequency resolution. The true point-by-point AWG implementation improves signal integrity for arbitrary waveforms by producing significantly less jitter and distortion than a DDS-based architecture. Custom arbitrary waveform generation is accomplished with a variable clock signal to reproduce each point stored in memory without skipping or repeating data points.

The 4047B is designed to integrate with B&K Precision's waveform editing software WaveXpress easily. This allows users to generate complex arbitrary waveforms that can be output via the instrument's 14-bit, 125 MSa/s, 16kpts arbitrary waveform generator.
