Spektrum Analysator

Brel&Kjaer
2131



1977: Der Brüel & Kjaer 2131 war der erste von Brüel & Kjaer und auch weltweit angebotene voll digitale Analysator und damit ein Meilenstein:
"The Digital Frequency Analyzer Type 2131 was the world's first 100% digital filter analyzer and designed to measure and display octave and 1/3-octave spectra in real-time.
The magic word was "digital" - reliability increased by a factor of ten and the test and calibration time decreased by the same factor."

Eigenschaften:
* Realzeit - 1/3 Octav-Analyse in 42 Kanälen mit Mittenfrequenzen von 1,6 Hz bis 20 KHz
* Realzeit Oktavenanalyse in 14 Kanälen mit Mittenfrequenzen von 2 Hz bis 16 kHz
* Digitaler Effektivwertdetektor für weiten Crestfaktorbereich
* Grosses Display mit 60 dB Dynamikbereich und alphanumerischem Read-Out
