Rion NX-42RT Real Time Octave/Third Octave Option for the Rion NL-52/42

Rion NX-42RT Real Time Octave/Third Octave Option for the Rion NL-52/42

The Rion NX-42RT program card adds real time octaves and third octaves and effectively an additional broad-band channel for some specific parameters to the Rion NL-52/42. Real time octave or third octave bands can be measured and logged. The NX-42RT enables the full measurement and logging capability of the NL-52/42 to be carried out in octave or third octave bands. You can, for instance, log processed third octave levels (say 1 hour Leq, Lmax, and 5 x statistical indices) and short duration samples (e.g. 100 msec samples) simultaneously. Independent control of the frequency weighting of the octave/third octave band levels and the broad-band levels measured on the main and sub-channel allows you to make the measurements in the way that best suits the job and your data analysis requirements.

  • Octave band analysis 16 Hz 16 kHz or Third octave analysis 12.5 Hz 20 kHz
  • Full logging logging capability of NL-52/52 maintained but in octaves or third octaves
  • Independent weighting can be applied to main channel, sub-channel and the third/octave bands
  • Choice of 'Band' or Main or sub-channel based maximum levels allows you to choose whether to measure the frequency content of the LAmax for example or the maximum level in each band
  • 'Partial o/a' feature allows you to log the time profile of a user-selectable frequency range
  • Any octave or third octave band (or main of sub channel) level can be used to trigger 'event recording' when used with NX-42WR audio recording option
  • Overlay analysis allows you to compare measured levels to a stored reference spectrum
