Kalibrasi MEGURO Electronics MAK-6578A - 2-Channel Automatic Distortion Meter

The MAK-6578A is a remotely controllable automatic distortion meter that measures 400 or 1000Hz harmonic distortion and levels in the range 10Hz to 100kHz simultaneously on 2 channels. Automatic frequency switching enables automatic frequency selection. Also even for measurement of distortion of signal waveforms whose levels changes, full-scale calibration is not necessary, making the MAK-6578A ideal for applications requiring very high-speed measurement, such as production lines. The MAK-6578A has a very-low 0.003% range among its distortion measurement ranges, enabling measurement of very-low distortion down to 0.001%. Furthermore, back-up functions are provided so that the measuring conditions need not be set each time the power is switched on.

		FEATURES
