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.

Keithley 2015 THD and Audio Analysis Multimeter Series Product Description
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 instruments | Offers 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 sweeps | Characterize 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 filters | Filter 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 |
