BK4047B

The BK4047B from B&K Precision is a 20MHz dual channel function/arbitrary generator model. This generator is capable of generating stable and precise sine, square, triangle, pulse and arbitrary waveforms. The CH1 and CH2 outputs are fully independent with individual on/off buttons and can both be varied from 0 to 10Vpp into 50 ohm (up to 20Vpp into open circuit). The generator provides 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 let's to set a large DC offset (e.g. ±4.99V) with a small amplitude output signal (e.g. 10mV). This dual architecture typically found in more expensive generators only, provides all the benefits of a DDS and a true point-by-point arbitrary waveform generator (AWG) without any limitations imposed by either technology.
