Description

This Current Amplifier provides high gain, low noise, current suppression, and high speed.

The features 8 decade ranges from 10E+4V/A to 10E+11VA.

Current suppression features permit examination of small currents in the presence of larger steady currents.

Applications using scanning electron microscopes, mass spectrometers, and photomultiplier systems can be used with the 427 for enhanced measurements of small component signals.
