Keithley 2015 THD Multimeter

Total Harmonic Distortion and Audio Analyzer Multimeter
The Keithley 2015 Series total harmonic distortion and audio analyzer multimeters combine audio band quality measurements and analysis with a broad purpose 6½-digit DMM—all in one half-rack instrument. They can measure total harmonic distortion (THD) over the complete 20Hz to 20kHz audio band and can compute THD+Noise and signal-to-noise plus distortion (SINAD). The 2015-P and 2016-P directly identify peak values of the frequency spectrum.
