Model 2015 Total Harmonic Distortion, 6-1/2-Digit DMM

The Model 2015 Total Harmonic Distortion Multimeter combines audio band quality measurements with a full function 6-1/2-digit DMM. This multimeter computes Total Harmonic Distortion (THD), THD+noise, SINAD, and individual harmonics. The 2015 has programmable audio-band sine wave sources for generating stimulus signals. A second source output, the inverse of the first output, combined with the first output, provides a differential source output. The Model 2015 has a 4Vrms single-ended output and an 8Vrms differential source output. The 2015 contains programmable low-pass and high-pass filters that can be combined to form a bandpass filter. In addition, five standard communication filters (CCITT, CCIR, C-message, A-weighting, and CCIR/ARM) are available for shaping the input signal for audio and telecommunications applications. The 2015 is optimized for minimizing production test time. This instrument can execute a sweep of 30 frequencies and output both voltage and THD at each frequency in only 1.1 seconds. All this audio measurement capability is combined with a DMM so that one instrument can replace two instruments in a test system.
