This document describes the features and characteristics of the B6 DDS function generator, including DDS technology and FPGA chip design, frequency range, high frequency accuracy and stability, frequency resolution, etc.
The SFG‑2000 and SFG‑2100 series are DDS‑based function generators that provide sine, square, and triangle waveforms with selectable frequency ranges up to 10 MHz, 100 mHz resolution, and ±20 ppm accuracy and stability. They include built‑in 6‑digit counters (SFG‑2100 series), AM/FM modulation, LIN/LOG sweep modes, and 10 groups of front‑panel setting memories.
Key specifications include a 10 Vpp amplitude into 50 Ω, harmonic distortion as low as –55 dBc (0.1 Hz‑200 kHz), and a compact AC power requirement (115‑415 V, 50/60 Hz). The unit measures 107 × 266 × 293 mm and weighs about 3.1 kg. Ordering information lists each model with its respective frequency range and feature set.

The SFG‑2000 and SFG‑2100 series cover frequencies from 0.1 Hz up to 10 MHz depending on the model.
The generators provide front‑panel setting save/recall with 10 groups of setting memories.
The sine‑wave harmonic distortion is –55 dBc from 0.1 Hz to 200 kHz.
It operates from an AC source of 115 V‑415 V, 50/60 Hz.
