The General Radio random-noise generators produce electrical noise at high output levels, each model having been designed for specific uses. The 1382 is intended for audio-frequency electrical, acoustical, and psycho-acoustical applications.

The General Radio 1382 Random Noise Generator provides white, pink, or ANSI noise spectrum with variable output up to 3 V RMS.

**Predictably random**  
The 1381 and 1382 are companion instruments that generate truly random noise from a semiconductor source. Special precautions are taken to ensure a symmetrical, Gaussian amplitude distribution. Output level is adjustable from below 3 millivolts to 3 volts rms behind a 600-ohm source impedance. Each model is constructed in a 3½-inch-high, half-rack-width cabinet, convenient for bench use and two can be mounted side-by-side in a relay rack.

Either of these noise generators can be used for simulation of noise in signal paths, as test-signal sources, or for demonstrations of statistical and correlation principles. The different features of the two offer a choice to match your needs.

The 1382 generates noise in the 20-Hz to 50-kHz band and is intended for electrical, acoustical, and psycho-acoustical tests. It offers three spectra, white (flat), pink (-3 dB per octave), and ANSI. The output can be taken balanced or unbalanced, floating or grounded.

Spectrum of 1382: Choice of 3 shapes. White Noise (flat spectrum, constant energy per hertz bandwidth): ±1 dB, 20 Hz to 25 kHz, with 3-dB points at approximately 10 Hz and 50 kHz; Pink Noise (constant energy per octave bandwidth): ±1 dB, 20 Hz to 20 kHz; or ANSI NOISE, as specified in ANSI Standard Sl.4-1961.
