K4301 - Pink noise generator

Description

In order to test the acoustics of a room (flat), you need: a pink noise generator together with a spectrum analyzer (eg K4300), as well as a good microphone with a linear characteristic. If we also have an equalizer, you can not only control, but also correct the acoustic deficiencies of the listening rooms.

It is possible to adapt the system to generate white noise.
