1405



Der Brüel & Kjaer Rauschgenerator Typ 1405 liefert wohldefiniertes Weißes Rauschen im Frequenzbereich von 20 Hz bis 100 kHz. Der Generator besitzt ein eingebautes -3 dB / Oktave Filter, welches zur Bewertung des weißen Rauschens benutzt wird, um rosa Rauschen im Frequenzbereich von 20 Hz bis 50 kHz zu erzeugen. Das eingebaute Filter kann auch einzeln benutzt werden.

Bitte fragen Sie nach den zusätzlichen Kosten für eine rückführbare ISO Kalibrierung.

English translation of German description:
The Brel & Kjaer Noise Generator type 1405 is designed to supply well defined white noise in the frequency range 20 MHz to 100 kHz. The generator has a built-in -3 dB/octave filter which is used to weight the white noise in order to produce pink noise in the frequency range 20 Hz to 50 kHz. The filter may also be used separately for other weighting purposes such as automatic bandwidth compensation. The generator also contains a compressor amplifier which is useful when performing frequency response measurements in various applications within the fields of sound and vibration. In such cases the noise generator is often combined with a filter in order to obtain a narrow band signal which is then used to control the compressor. Also the compressor amplifier may be used separately.

Features:

* White noise in the frequency range 20 Hz to 100 kHz
* Uniform spectral density 10 exp4 V /Hz
* Pink noise in the frequency range 20 Hz to 50 kHz
* Built-in -3 dB/octave filter can be used separately
* Built-in compressor amplifier with meter
* Six compressor speeds
* Signal/hum ratio better than 90 dB
* Manual and remote generator stop
* Mains or external battery operation.

Please ask for the additional fee for a current and traceable ISO calibration.
