The Wavetek 21 is a stabilized function generator delivering precise signal generation from 100 µHz to 11 MHz. Built for laboratory testing, electronics development, and telecommunications applications, it combines digital synthesis below 1.1 kHz with analog generation at higher frequencies. Engineers can select from eight waveforms—sine, triangle, square, ramp up, ramp down, haversine, havertriangle, and DC—with continuous, triggered, or gated operation modes.
