The Wavetek 1045 is a versatile signal generator engineered for laboratory and bench testing applications across a wide frequency spectrum. It generates sine, square, triangle, and ramp waveforms from 0.004 Hz to 4 MHz with independently adjustable amplitude and DC offset, delivering 50 ohm output impedance. The instrument operates from either 115 or 230 VAC (50–400 Hz) at less than 5 watts typical power consumption, housed in a compact 7.75″ W × 5.25″ H × 7.5″ D chassis weighing approximately 8 pounds.
