6½-Digit THD Multimeters 6½-Digit Audio Analyzing Multimeters

Product catalog summary

Overview: The Keithley Models 2015-P, 2016-P, 2015, and 2016 are advanced digital multimeters (DMMs) designed for audio analysis and total harmonic distortion (THD) measurements. They combine high-quality audio band measurements with a 6½-digit DMM, suitable for various applications including voltage, resistance, current, frequency, and distortion measurements.

Specifications: Models 2016 and 2016-P offer higher sine wave generator output than Model 2015, suitable for test signals over 8Vrms. The 2015-P and 2016-P models have additional processing capacity for frequency spectrum analysis.

Frequency Domain Distortion Analysis: These models use DSP-based processing for frequency domain analysis, measuring THD across the 20Hz to 20kHz audio band with low residual distortion. They can compute THD+Noise and SINAD, and report individual harmonic magnitudes.

Applications: Ideal for wireless communication device audio quality testing, component linearity testing, and lighting and ballast THD limit conformance testing. They feature a 20Hz–20kHz sine wave generator and fast frequency sweeps.

Optimized for Production Testing: Capable of fast frequency sweeps, enabling high-speed audio performance testing in production environments without sacrificing quality.

Dual Output Source: Includes an internal audio band sine wave source with a second output for testing differential input circuits.

Audio Filters: Provides five industry-standard bandpass filters, including CCITT, CCIR, C-message, CCIR/ARM, and "A" weighting filters for noise filtering and system transmission characteristic simulation.

Measurement Flexibility: Offers a comprehensive set of DMM functions, including DCV, ACV, DCI, ACI, temperature, frequency, period, dB, dBm, and continuity measurements.

Noise Measurements: Capable of measuring both wide band and narrow band noise, allowing for frequency domain measurements of RMS voltage noise over the audio band.

Spectrum Analysis: Models 2015-P and 2016-P can identify and report peak values in a frequency spectrum, simplifying analysis without external software.

Accessories and Services: Various cables, adapters, and rack mount kits are available, along with extended warranty and calibration services.

Test engineers can make a broad range of voltage, resistance, current, frequency, and distortion measurements, all with the same compact, half-rack measure-ment 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, DSP-based processing allows the Models 2015-P, 2015, 2016, and 2016-P to provide frequency domain analͭysis 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. (See Figure 1.) Q o -t» T3 'rz.
