NOISE GENERATOR 8121C

Model-8121C uses a logic circuit to generate “Pseudo Random Noise”, it is the newest and the most advanced design to generate audio white noise. It has a much flatter frequency response than using a diode. Model-8121C has (1) a White noise source. (2)Weighting filters.(3) a Built-in power amplifier. (4)” TRUE RMS ” voltage meter circuit. It can generate five different kinds of noise spectrum, including White Noise, Pink Noise, and three kinds of “Weighted Noise”, conforms to the following nation’s standards:(1) JIS C5531, IEEE 219, CNS 4785 (2) EIA 426B(3) DIN 45573

Technical specification：
