Model 4071
Synthesized Arbitrary Waveform Generator

Function Generator Pricing

The B+K Model 4071 31.5 MHz Synthesized Arbitrary Waveform Generator represents the finest single source for signal generation to date.

Combining the latest DSP and DSS technologies, the 4071 offers a number of operating modes, providing a versatile, cost effective signal source. You will find the 4071 is the best value and most capable instrument for any bench.

 

Arbitrary Waveform Generator, Sweep Function Generator, Pulse, VCO, AM, FM, Ø Modulation, FSK and Burst Modes are all accessed quickly and easily from the front panel keypad. Being a true 12 bit arbitrary generator, the 4071 is stable, accurate and drift free. Unlike competitive models, the 4071 generates every data point independently of the repetition rate instead of a simple look up table.

Custom design waveforms on a PC, or download from a number of sources, spread sheet, oscilloscope or application program the 4071 will perform like no other signal source.
