Product Description

PRODUCT INTRODUCTION

The LSPEC 4601 Weak voltage ampl ifier is a

high-performance desktop low noise preamplifier that

uses a novel circuit topology and precision electronics

to amplify extremely weak voltage signals. Amplifier

magnification times can be adjusted, input mode can

be single-ended or differential, built-in signal filter can

be set, support signal reversal and blanking, can be

widely used in weak voltage signal detection field.
Application field

It can be widely used in research, education, medical, photoelectric detection, electromagnetic

detection and other fields involving weak voltage signal detection.
