Model 4070A
Synthesized Arbitrary Waveform Generator

Function Generator Pricing


 The B+K Model 4070A 21.5 MHz Synthesized Arbitrary Waveform Gen. with software represents the finest single source for signal generation to date.

Combining the latest DSP and DSS technologies, the 4070A offers a number of operating modes, providing a versatile, cost-effective signal source. You will find the 4070A 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 4070A is stable, accurate and drift free. Unlike competitive models, the 4070A 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 4070A will perform like no other signal source.
