New Spectral Limits Option for XL2 Analyzer NTi Audio
XL2. It is a firmware module that extends the function range for the XL2 by
trace capturing, relative curve display and comprehensive tolerance
handling for the FFT Analysis and the new high resolution RTA function
with spectral resolutions up to 1/12th octave.
The new Spectral Limits Option adds an additional RTA Analyzer with
selectable spectral resolutions of 1/1, 1/3rd, 1/6th and 1/12th octave. It also
allows capturing of multiple traces in the internal memory. Measurements can
be either displayed as absolute traces or shown relative to previously stored
traces. This powerful functionality simplifies comparison of frequency
responses and adjustments to an ideal response curve.
Tolerance handling
Spectral measurement can be compared against a tolerance curve and
exceptions are visualized in every frequency band. Out-of-tolerance conditions
are further visualized by the bicolor “limit” button and forwarded to the I/O
interface of the instrument in order to drive an external alarm device such the
accessory SPL Stack Light.
Tolerance curves can either be imported from txt-files or directly derived from
captured measurements. The XL2 calculates tolerances based on single
reference data, the mean average or Min/Max of multiple captures.
FFT module
For higher frequency resolutions beyond 1/12th octave the Spectral Limits
Option activates the tolerance handling and capturing in the real time FFT
function. With the zoom functionality of FFT, any frequency band with spectral
resolutions of up to 0.4 Hz can be defined and monitored with tolerances.
The Spectral Limits Option is available for all XL2 Audio and Acoustic Analyzers
now. Read more at www.nti-audio.com/XL2.
