The Flexus FX100 supports the simultaneous measurement of Total Harmonic Distortion with or without Noise, as well as the upper harmonics k2 - k35. Furthermore, a 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:
With the balanced XLR and unbalanced RCA inputs, the XL2 is a comprehensive audio analyzer. It simultaneously measures level, distortion (THD+N) and frequency. The internal loudspeaker or headphone is used for audible monitoring of the test signal or the residual distortion. The optimized low-distortion and low-noise design allow level measurements down to -112 dBu and residual distortions typically lower than -100 dB, which is unmatched in handheld instruments.
