INTORDUCTION

This noise measurement amplifier, ATNMA1.0, 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.
This noise measurement amplifier assembly has 5
portions:

300,000×:
Measure the noises less than 0.1µV. Toggle magnification
switch S2 to S2-3 and S5 to S5-3.
10,000,000×:
Measure the noises less than 1nV. Toggle magnification
switch S2 to S2-3 and S5 to S5-3.
Please see the switches location in figure 2 and figure 3.
