Keithley 2015 Series: THD and Audio Analysis 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 8Vrms.

Features

Benefits

Frequency domain analysis in conventional time domain instrumentsOffers broad range of measurements in one compact, half-rack instrument

Dual output audio band sine wave source

Generate stimulus signals with one output; the second one (inverse of the first output) simplifies testing differential input circuits for common mode or noise cancellation performance
Fast frequency sweepsCharacterize audio-band circuitry quickly in production test systems
Up to 64 harmonic magnitudes can be included in the distortion measurement Optimize accuracy, speed, and complexity for a specific test by programming the number of harmonics to be included in a computation
5 standard audio shaping filtersFilter out electromechanical noise on the production floor or simulate other types of system transmission characteristics
13 DMM functions (6½ digits)Minimize added equipment costs when configuring test setups

Audio Analysis Testing Using a KPCI-3108 Board with LabWindows/CVI 5.0.1 Application Note # 2397 Manufacturers of cellular and cordless telephones employ a variety of methods to test the audio quality of their products during production. These tests may be as simple as measuring the Vrms of a sinewave input signal that is passed through the analog microphone and speaker circuits. In this case, a DMM usually offers sufficient measurement capability.
