Four-channel Sound & Vibration Analyser [SVAN 958A]
SVAN 958A Class 1 Four-channel Sound & Vibration Analyser is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants giving users an enormous measurement flexibility. The real advantage of SVAN 958A is the capability to perform advanced analysis simultaneously to the level meter mode. In practise this allows the user to obtain broad-band results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.
