The Lexus FX100 supports the simultaneous measurement of Total Harmonic Distortion with or without Noise, as well as the upper harmonics k2 - k35. Furthermore, an user-defined selection of harmonics may be summed together, and individual Pass/Fail limits may be applied. The distortion measurements are available in the Meter, GlideSweep or StepSweep mode.
Example of GlideSweep THD:
Together with the balanced XLR and unbalanced RCA inputs includes the XL2 a comprehensive audio analyzer. It measures simultaneously level, distortion (THD+N) and frequency. The internal loudspeaker or headphone output offers audible monitoring of the test signal or just listening to the residual distortion. The optimized low distortion and low noise design enable level measurements down to -112 dBu and residual distortions typically lower than -100 dB, which is unmatched in handheld instruments.
