B+K Precision BK407xC Series Dual-Channel Function and Arbitrary Waveform Generators
BK4078C (30 MHz) and BK4079C (50 MHz) Signal Generators
The B&K Precision BK4078C and BK4079C are dual-channel function and arbitrary waveform generators that utilize true point-by-point arbitrary waveform generation, producing less jitter and distortion than solutions relying on typical DDS architectures. The features a frequency range of 30 or 50 MHz, 16 bit resolution, a sampling rate of up to 250 MS/s, deep waveform memory up to 4 Mpts per channel, and 128 MB storage capacity. Standard USBTMC and LAN interfaces combined with the 407XC software, allow users to remotely upload custom waveforms and also convert binary, CSV, and text files with waveform data into an arbitrary waveform (.arb) file. A GPIB interface is available with model BK4079C-GPIB.
