簡介
EL-LNA-2
The amplifier EL-LNA-2 is designed as a differential low noise amplifier with two gain stages of x10 and x100 with a full bandwidth of 20 MHz (at G=10)
While the EL-LNA-2 is matched to connect to an Elsys high-precision Transient Recorder it is also suitable for any 3rd party data acquisition system.
