Keithley 2015 THD and Audio Analysis Multimeter Series

Frequency Domain Analysis in Conventional Time Domain Instruments

The 2015 series 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.

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
