The 2015 total harmonic distortion multimeters combine audio band quality measurements and analysis with a full-function 6-1/2 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. Perform fast frequency sweeps for characterising audio-band circuitry in production test systems. For example, the instrument can execute a single sweep of 30 frequencies and transmit both rms voltage readings and THD readings to a computer in only 1.1 seconds.
