PA714 Pulse Amplifier
The PA714 Pulse Amplifier is a meter-mounted device that amplifies and conditions low amplitude signals such as those developed by a magnetic pickup coil. The amplitude of the squarewave output equals the input supply voltage of the PA714. Signal amplification and conditioning permits trouble free interfacing between low amplitude signal sources and electronic devices requiring pulse inputs.

- Description
The PA714 Pulse Amplifier is a meter-mounted device that amplifies and conditions low amplitude signals such as those developed by a magnetic pickup coil. The amplitude of the squarewave output equals the input supply voltage of the PA714. Signal amplification and conditioning permits trouble free interfacing between low amplitude signal sources and electronic devices requiring pulse inputs. The sensitivity adjustment permits the PA714 to discriminate between an
input signal and noise by increasing (CCW) or decreasing (CW) the input signal amplitude necessary to be processed as a valid signal. This, in conjunction with direct mounting, allows the PA714 to operate effectively in noisy environments. - Documentation
