Abstract :
A phase-angle generator made by phase locking two function generators is described. The generator produces two sine waves that are programmable in phase (0-360°), amplitude (0-40 Vrms ), and frequency (<1 Hz-20 MHz). Phase linearities with±0.1° are achieved without external phase standards
