Hewlett-Packard's 3312A Function Generator combines two separate, independent function generators with a modular section in one compact instrument.

The main generator can-via pushbutton control-be triggered by the modulation generator to provide sweep functions, AM, FM or tone burst.

Ten Vp-p into 50 Ω provides adequate power for most applications. The output attenuator has a range of more than 10,000:1 so clean low-level signals from 10V to 1 mVp-p into 50 Ω can be obtained. The main generator includes dc offset up to 10 volts p-p into 50 Ω.

The HP 3312A is an effective low cost solution for generating a multitude of functions.
