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.
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 |
