The 3312A Function Generator combines two separate, independent function generators with a modulator 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 V p-p into 50 O provides adequate power for most applications. The output attenuator has a range of more than 10,000:1 so clean low-level signals from 10 V to 1 mV p-p into 50 O can be obtained. The main generator includes dc offset up to 10 volts p-p into 50 O.
