RION Random Noise Generator SF-06

Sound source for all kinds of acoustic measurements.

* White and pink noise based on m-sequence pseudo random noise
* M-sequence repeat cycle 12 hours (logical value), with 50 kHz sequence clock
* Nine selectable 1/1 octave band filters with center frequencies from 31.5 Hz to 8 kHz. Multiple adjacent bands can be selected and used together.
*Choice of noise output modes: continuous, automatic burst, manual, extremal trigger
*Integrated serial interface allows external control from a computer
*Side-mounted connector panel allows use of the unit in an upright position
