FFT Analysis
Compares the high-resolution acoustic pattern of any device against a pre-defined reference sample with a pass/fail analysis in linear X-scaling.
1/12 Octave Analysis
Passed/Failed measurements with selectable 1/1, 1/3, 1/6 or 1/12 octave band resolution in logarithmic X-scaling.
Pass/Fail Measurements
The XL2 Analyzer captures the frequency spectrum of reference speakers/microphones and supports generation of tolerance bands based on the captured reference data. Measurements can either be displayed as absolute traces or shown relative to previously stored traces. Frequencies with failed results are individually visualized in every frequency band.
Stack Light
Provides visual pass/fail indication.
Auto-start Function
Measurement starts by automatic level trigger, external foot switch or instrument start button.
Tolerance Management
Tolerance curves can either be imported from txt-files or directly derived from captured measurements. The XL2 calculates tolerance bands based on
- Single captured results
- txt-files manually generated on the PC
- Mean average of multiple captures
- Min/Max curves of multiple captures
Digital I/O Adapter PCB
For automated operation with external peripheral devices the XL2 Analyzer can be linked into a programmable logic controller. The Digital I/O Adapter is tailored for rail mounting in electric switch boxes.
