Wavetek 20

The Wavetek 20 is a function generator that produces sine, triangle, square, pulse, and DC offset waveforms across a 0.002 Hz to 2.1 MHz frequency range. Seven overlapping decade ranges with 1000:1 multiplier per setting enable precise signal generation for circuit analysis, testing, and educational applications. External modulation and sweep capability extends functionality across three decades per range.
