The adjustment range of this generator is in excess of 1,000,000/1, using a single frequency-adjust potentiometer. C1, C2, and C3 shape the triangular signal between 500 kHz and 1 MHz. C4, C5, and the 50-kΩ trimmer are adjusted to maintain essentially constant (±10%) amplitude up to 1 MHz. Harris Semiconductor, Linear and Telecom ICs, 1991, p. 3-224.
