This legendary model introduced in 1965 HP Model 3300A function generator features two channel output of square, sine and triangle waveforms. .01 to 100Khz.

Variable attenuators on both channels.

Frequency Range: 0.01 Hz to 100 kHz in 7 decade ranges.

Output Impedance: 600 ohms nominal.

Maximum output per channel : >35 volts p-p open circuit, >15 volts p-p into 600 ohms, >2 volts p-p into 50 ohms

Unit is in good working condition as pictured, I have run sine, square, triangle wave from both outputs and all working just fine. This vintage unit would probably benefit from calibration. Unit is very clean inside, no corrosion or bulging caps.
