Keithley 2015 Total Harmonic Distortion THD Multimeter 6.5-Digit


The Keithley 2015 Total Harmonic Distortion Multimeters combine audio band quality measurements and analysis with a full-function 6-1/2-digit Digital Multimeter. Test engineers can make a broad range of voltage, resistance, current, frequency, and distortion measurements, all with the same compact, half-rack measurement instrument. Specifically, the harmonic distortion multimeters allow for high performance and broad-purpose frequency domain measurements and spectrum analysis.


  • THD, THD+Noise, and SINAD measurements
  • 5 standard audio shaping filters.
  • 20Hz-20kHz sine wave generator
  • 13 Digital Multimeter functions (6-1/2 digits).
  • Fast frequency sweeps.
  • 4Vrms single-ended or 8Vrms differential output.
  • Individual harmonic magnitude measurements.
