Keithley 2015 Series Total Harmonic Distortion 6-1/2 Digit Multimeter

Our audio analyzing 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. The 2016 and 2016-P have twice the sine wave generator output of the 2015 for applications that require test signals greater than 8 V rms.
