The B+K Model 4070A represents the finest single source for signal generation to date. Combining the latest DSP and DDS 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. • Arbitrary Waveform Generation Design custom waveforms on your PC and download for generation 40 MS/s max update rate 12 bit resolution, 32K buffer. Arbitrary waveforms may be designed with a graphical Windows®-based design tool, which is available for free download from www.bkprecision.com. • Function Generator Generate Triangle, Ramp, Sinewave and others. • Pulse Generator Digital waveforms with an adjustable duty cycle. • High Stability Timebase Guarantee ±5 ppm frequency over 32 ̊ to 104 ̊F (0 to 40°C) range.
