Amber Technology XL2 handheld audio analyser

The XL2 handheld audio analyser has a combination of sound level meter, acoustic analyser and powerful audio analyser.

The firmware module extends the device’s functionality with trace capturing, relative curve display, tolerance handling for FFT analysis and a high-resolution RTA function with spectral resolutions up to 1/12th octave.

The spectral limits option adds an additional RTA analyser with selectable 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 either be displayed as absolute traces or shown relative to previously stored traces. This functionality simplifies comparison of frequency responses and adjustments to an ideal response curve.

Spectral measurements can be compared against a tolerance curve and exceptions displayed in every frequency band. The curves can either be imported from text-files or directly derived from captured measurements.
