Audio Recording
The XL2 Analyzer may record a linear audio file (48 kHz, 24 Bit)
of the measurement period together with the spectral data. Just
load a txt-file named “12audio.txt” in the root directory of the
XL2. This requires the installed option Extend Acoustic Pack.
Capture References and Create Tolerances
The Spectral Limits Option extends the function range of the
XL2 with trace capturing, relative curve display and compre-
hensive tolerance handling for the FFT Analysis and the high
resolution 1/12 Oct + Tol spectral analysis.
