Micro-current preamplifier

The analog signal obtained by some sensors in the nuclear measurement is a weak current signal, so it is necessary to measure the weak current. Accurate measurements of weak currents are required, and these measurements require current measurements at the PA level or fA level. The performance of the weak current preamplifier directly affects the performance of these test equipment. Our company can provide excellent performance of miniaturization, modular fA class weak current amplifier, after the purchase can be directly assembled in their instruments. This will greatly improve the performance of their equipment and speed up the progress of their work. Main technical indicators 1, frequency range: DC-30K
