Model 2015 Total Harmonic Distortion (THD), 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.
