Taiwan Sunshine 8121C noise signal generator I. Features presentation is a high stability of the noise source, the pointer voltmeter circuits, filters and amplifiers four parts by noise signal generator. Noise types: a white noise frequency range: 20Hz-100 kHz (-3dB cutoff point, the slope of the least -24dB / 0ct) amplitude-frequency flatness of ± 1dB. 2, pink noise frequency range: 20Hz-20 kHz (-3dB cutoff point, the slope of the least -24dB / 0ct) sound pressure sensitivity is 4. 3, IEEE 219 weighted noise. Accord: IEEE 219, CNS4785, IEC268-5, JISC55531. 4, EIA RS426B weighted noise. 5, DIN 45573 weighted noise. Second, the main purpose of the continuous load capacity can be a speaker, speaker box, headphone splitters and other electro-acoustic sound product testing, and set a rated input power of the product, to detect a speaker's sound pressure sensitivity and with a spectrum analyzer to test the speakers The frequency response curve. Third, the technical parameters of the voltmeter: RMS into Hi / Lo two tranches Lo: 0 ~ 6 V Hi: 0 ~ 30 V Accuracy: <± (1% rdg + 1.0% FS.) Amplifier: a.100W continuous Adjustable output (no clamp sine wave output, whichever part of the maximum) b Frequency response:. 20 Hz ~ 20 kHz ± 0.2dB 20 kHz ~ 100kHz ± 1dB c distortion:.. <0.1% d short-circuit protection, permanent short circuit and will not damage the instrument e load impedance: ≧ 2 Ω Description: GVS8121E external output increased 5 basis GVS8121C on; output the five kinds of different signals, which can use five different noise signals on the product tested. convenient and efficient.
