White And Pink Noise Speaker Tester Model 8121c - Machine Weight: 11 Kilograms (Kg)

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