Standard Description Description GR / General Radio 1382 Pink/White Random Noise Generator The Type 1382 Random-Noise Generator provides a high level of true random electrical noise at its output terminals. This type of signal is useful in room-acoustics studies, loudspeaker and microphone tests, psycho-acoustic tests, filter tests, crosstalk measurements, calibration checks on recording systems, modulation of signal generators and test oscillators, shaker-driven vibration tests, and airborne vibration tests. It can also be used for tests of the rms response of meters, observation of resonances in systems, electrical averaging of resonant responses, comparisons of effective bandwidths, and for other tests when a signal with a high peak-to-rms factor is useful, as in overload testing. The choice of spectra and the provision of a balanced output make the Type 1382 Random Noise Generator particularly suitable for audio and acoustical applications. A pair of these generators can be used as signal sources for the demonstration of various degrees of correlation, possible errors of random sampling, and other concepts of statistical theory. Specifications Spectrum: (a) "White" noise (constant energy per cycle bandwidth) ±1 dB from 20 Hz to 20 kHz, with 3-dB-down points at 10 Hz, approximately, and 50 kHz; (b) "Pink" noise (constant energy per octave bandwidth) ±1 dB from 20 Hz to 20 kHz; or (c) "USASI" noise, for calibrating sound-level meters, as specified in USASI Standard S1.4. Output Impedance: 600 ohms, balanced or unbalanced. Output may be shorted without causing d1stortion. The item is in good condition, tested and working. A power cord is included.
