HM8027 (HAMEG)

he HM8027 Distortion Meter was developed for the measurement of harmonic distortion in the audio frequency range. Due to its low inherent distortion of 0.005% (1kHz), it is ideally suited for tests and measurements of high-grade audio systems. The digital display allows distortion readout with a maximum resolution of 0.01%. In addition, the HM8027 has the option to visually check the residual distortion of the measured signal on an oscilloscope connected to its control output. This feature enables a qualitative evaluation of the reading for signals with noise or cross-over distortion beyond the indicated distortion value. Test frequency adjustments are performed via a rotary dial and push-button frequency range selectors. The automatic frequency fine-tuning with a 15% capture range ensures fast and easy operation of the HM8027. The Distortion Meter HM8027, combined with the Sine Wave Generator HM8037, provides a complete test system to be used primarily in the audio frequency range. The clearly arranged front panel assures problem free operation.
