TEST EQUIPMENT PR0N: THE HP 3312A

 HP 3312A FUNCTION GENERATOR combines two separate, independent function generators with a modular section in one compact instrument.

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

Ten V p-p into 50 Ohm 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 Ohm can be obtained.

The main generator includes dc offset up to 10 volts p-p into 50 Ohm.
