SPL/Spectrum
Index
Use the SPL Meter/Spectrum Analyzer type to see -
The level of any sounds on the SPL meter face.
Options:
 Select the meter damping type: Impulse, Fast, Slow or Slowest.
 Read the Peak, Maximum or Minimum values sensed since the Reset button was last clicked
 Choose the response weighting to use at the top of the tab page: A, B, C, or None.
 When A weighting is selected, you can read the Sound Exposure Level (SEL) over time spans
starting from a click of the Begin circle to a click of the End button.
The spectrum of any sounds, on the Spectrum Analyzer graph.
Options:
 Choose the FFT format for display in terms of "Hertz" frequency bandwidth. This format
allows you to choose the amount of smoothing applied.
 Choose the RTA format for display in terms of "octave" frequency bandwidth. Display will be
separated into 1/6th octave bands.
 Choose the response weighting to use at the top of the tab page: A, B, C, or None.
 Don't use the Spectrum Analyzer to measure frequency response -- the Frequency
Response analyzer is much better for that function!
 You can select the damping type for either analyzer graph from: None, Impulse, Fast, Slow or
Slowest
