CEL-600 Series Real Time Analyzers
The following all new DSP based CEL-600 noise analyzers feature real time (or parallel) data calculations for multiple overall measurements and optional frequency analysis capability. This makes them suitable for tackling any sort of noise problem since all of the frequency information is gathered simultaneously. These meters can measure steady, variable or impulsive noises very quickly and efficiently and are ideal for solving difficult noise problems in the shortest possible time. Currently 2 main models are available featuring a broadband integrating (or averaging) meter (CEL-620A) and an octave band model (CEL-620B). Both type 1 and type 2 accuracy standards are available depending on the specific user's application.
