GENERAL DESCRIPTION
The F30PV is a broadband, high output current, general purpose linear amplififier designed for laboratory use. It is based on a fast operational amplififier with a feedback network chosen to give a voltage amplifification of 10 times. Any function or arbitrary waveform generator can be used as an input device. The amplififier combines very high speed with high output current. It is, thus, of the outmost importance for the safe operation that the user understands the possibilities as well as the limitations of the instrument. A functional diagram of the instrument is shown below:
INPUT AMPLITUDE
The amplififier has an attenuator at the input. At the knob position “10” the amplifification is equal to 10x. Standard value is 500 ohm, but 50 ohm, 1kohm or other values can be fifitted in on request.
The amplitude of the input signal should normally be kept within ±3.5 V. The input protection network limits the signal amplitude delivered to the power amplififier to a safe value. It also effectively cuts accidental spikes and overshoots. However, large and prolonged overvoltage at the input may blow the microfuse in the input protection circuit. (A spare fuse is provided inside the instrument. )
Keep input signals within ±3.5 V range.
Never connect the output to the input of the amplifier!
