This noise measurement amplifier, ATNMA2, is designed to test ultra low noises which cannot be measured by oscilloscope, such as nV and µV level noises, for electronic modules. This amplifier measures the noise signals through touching the point that needs testing, then amplifies the detected noise signals, and select the measuring range of frequencies. The rechargeable battery energy is 500mAH, can be used more than 20 hours. The rechargeable battery full voltage is 4.2V. The low noise amplifier includes one rechargeable battery, one coaxial cable, some probes.
