Micronetics NMA-Industrial wifi series products are specifically designed to perform interference tests for 802.11a, 802.11b and ISM products in general. The Gaussian output can simulate noise from other ISM devices sharing the same spectrum as well as thermal noise. By setting up an exact signal to interference ratio, one can measure bit error rate (BER) as well as test how well the system operates under real world conditions in general. The devices consist of a stable noise source and multistage amplifier for high output Gaussian noise output. The units have a built-in voltage control so output is stable even if your supply voltage is not. They can be ordered with optional TTL control to switch the noise off or on from microprocessor control. Lastly, the units are calibrated for noise spectral density output centered at each channel so you know precisely your interference signal level.
