Models 2015 Total Harmonic Distortion Multimeter
The Models 2015-P and 2016-P Audio Analyzing Digital Multimeters and the Models 2015 and 2016 Total Harmonic Distortion Multimeters combine audio band quality measurements and analysis with a full-function 61⁄2-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. The Model 2016 and 2016-P have twice the sine wave generator output of the Model 2015 for applications that require test signals greater than 8Vrms. The Model 2015-P and 2016-P offer additional processing capacity for frequency spectrum analysis.
Frequency Domain Distortion Analysis
For applications such as assessing non-linear distortion in components, devices, and systems, DSPbased processing allows the Models 2015-P, 2015, 2016, and 2016-P to provide frequency domain analysis in conventional time domain instruments. They can measure Total Harmonic Distortion (THD) over the complete 20Hz to 20kHz audio band. They also measure over a wide input range (up to 750Vrms) and have low residual distortion (–87dB). The THD reading can be expressed either in decibels or as a percentage. In addition to THD, the Models 2015, 2015-P, 2016, and 2016-P can compute THD+Noise and Signal-to-Noise plus Distortion (SINAD). For analyses in which the individual harmonics are the criteria of greatest interest, the instruments can report any of the (up to 64) harmonic magnitudes that can be included in the distortion measurements. The user can program the actual number of harmonics to be included in a computation, so accuracy, speed, and complexity can be optimized for a specific application.
