1381 General Radio Noise Generator

The 1381 is a used Noise Generator from General Radio. A noise signal generator is a type of electronic test equipment that produces a noise, or random signal, to test an electronic product’s frequency response, noise figure, and other important parameters.

Additional Features:

  • Frequency range: 2 Hz-50 kHz

The General Radio 1381 Random-Noise Generator generates truly random noise from a semiconductor source. The generated noise is flat down to 2 Hz and is intended for random-vibration tests and for general-purpose use in the audio and sub-audio range. The upper frequency limit (@3 dB) can be switched to 2, 5, or 50 kHz. Output level is adjustable from below 3 mV to 3 V RMS (600 ohms impedance) and can be clipped symmetrically at 2, 3, 4, or 5 times the RMS amplitude.
