• 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.
   
• Passed/failed measurements
  The XL2 Analyzer captures the frequency spectrum of reference devices, such as engines, rotary motors, fans, vacuum cleaners, etc. 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.
   
• Auto-start function
  Measurement starts by automatic level trigger, external foot switch or instrument start button.
   
• Stack light
  Provides visual passed/failed indication.
   
• 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
  • Manually generated txt-files 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 control. The Digital I/O Adapter is tailored for rail mounting in electric switch boxes.

• Turnkey Solution
  Multiple XL2 Analyzers connect with USB Device Servers to a network for online production control. Also wireless solutions are supported. An individual Projector Software may be started for each XL2 Analyzer, thus all XL2 screens are displayed on the monitor at one glance. The Projector Software offers to control each XL2 Analyzer from the host PC.

for Sound Level Monitoring provided with
Remote Measurement Option

• Individual Solution programmed by Customer
  The Remote Measurement Option allows querying the XL2 measurement data online via the USB interface. Multiple XL2 Analyzers can be implemented into a customer specific production test solution. The XL2 acts as a front end device for sound level and RMS/THD measurements.
