This document introduces the features and characteristics of B&K Precision 4017B 10MHz DDS Sweep Function Generator
The BK Precision 4017B is part of the 4000 series of function generators and introduces Direct Digital Synthesis (DDS) for precise, low‑distortion waveforms up to 10 MHz. It offers sine, square, ramp, triangle and pulse waveforms, a built‑in frequency counter, and a multi‑function LCD that shows frequency, level, offset and duty‑cycle.
The instrument provides a 50 Ω ±10 % output impedance, RS‑232 communication at a fixed 9600 bps, and a range of sweep and VCG modes. Detailed specifications cover frequency resolution, duty‑cycle resolution, rise times, distortion, and output levels for both standard and CMOS/TTL outputs.
