The Keithley 2015 Total Harmonic Distortion Multimeter combine audio band quality measurements and analysis with a full-function 6.5 digit DMM. Test engineers can make a broad range of voltage, resistance, current, frequency, and distortion measurements, all with the same compact, half-rack measurement instrument.
 

Features:

• THD, THD+Noise, and SINAD measurements
• 20Hz–20kHz sine wave generator
• Fast frequency sweeps
• 2015-P, 2016-P: Identifies peak spectral components
• 2015, 2015-P: 4Vrms singleended or 8Vrms differential output
• 2016, 2016-P: 9.5Vrms singleended or 19Vrms differential output
• Individual harmonic magnitude measurements
• 5 standard audio shaping filters
• 13 DMM functions (61/2 digits)

Applications:

• Wireless communication device audio quality testing
• Component linearity testing
• Lighting and ballast THD limit conformance testing
• Telephone and automotive speaker testing
