This noise measurement amplifier, ATNMA2, is designed for testing ultra low noises such as nanovolt or microvolt noises that cannot be detected by oscilloscopes. When it detects the noise signals, the noise measurement amplifier amplifies the noise to magnifications, 3,000×, 10,000×, 30,000×, 100,000×, 300,000×, 1,000,000×, 3,000,000×, according to different requirements. There are three noise measurement bandwidths: 0.1Hz ~ 10Hz, 0.1Hz ~ 1kHz, 0.1Hz ~ 100kHz.
The amplifier comes with a built-in rechargeable battery with 500mAH electricity, which can be used continuously for more than 20 hours. The maximum voltage of teh rechargeable voltage is 4.2V. There comes with an LED for indicating low battery. The noise measurement amplifier includes one rechargeable battery, one coaxial cable, and some probes. The input probes come with adjustable span. This noise measurement amplifier is 100 % lead (Pb)-free and RoHS compliant.
This noise measurement amplifier can work with most electronic modules, such as laser driver and TEC controller, etc. to detect and amplify ultra low noise during operation.
