Hewlett Packard Model 3300A function generator (1969)

The Function Generator presented here was manufactured back in 1969. Its frequency range is 0.01 Hz to 100 kHz for sine, square and triangle waves. The author acquired it in 1992, at an auction of used electronic equipment, for much less than its market value. The 3300A has been with me him then, playing an active role on the workbench whenever sinewave, triangle or square waves are required.
