A programmable function generator for dynamic analysis testing

A flexible function generator with high-resolution programmability of frequency, amplitude, and DC offset has been developed for structural dynamics testing. The generator consists of a clock generator which defines the signal frequency and memory tables which define the signal functions. In order to obtain a fast-settling, stable, accurate variable clock signal, a frequency-locked-loop circuit was developed.
