Amplifier Research NE3000
The Model NE3000 Comparison Noise Emitter is a broadband noise source, which can be used as a reference standard for comparison of different test sites (OATS, screened rooms, anechoic chambers, etc.). The continuous, broadband output of the device reduces the probability of missed resonances possible when using a non-continuous standard (comb generators, pulse generators, etc.). The device is self contained and batterypowered.
