The Pendulum Instruments Variable Gain High Speed Linear Amplifier F30PV is a very fast general purpose linear amplifier having a variable amplification of 0-10 times and capable of bipolar voltage output of ±35V. The amplifier has an attenuator at the input. At the knob position “10” the amplification is equal to 10x. Standard value is 500 ohm, but other values like 50 ohm, 1kohm, etc., can be fitted in on request. Any signal source with amplitude within ±3.5 V can be used as an input device. A typical output voltage range of a function generator will not harm the amplifier but the input protection network will limit the signal amplitude to ±3.5 V (after attenuator) and may cause clipping. The Variable Gain High Speed Linear Amplifier F30PV is equipped with a microfuse rated at 15 mA, which will be blown if the input voltage exceeds 300% of the maximum.
