200KHz / 10000Freq.Point LCR Meter
MCH-2816A
It has high test frequency of 300kHz and 0.01Hz stepping arbitrary programming, and it has 10mV-2V signal level, all making it meet the precision test requirements of production line quality control, in-coming inspection and lab. Its HANDLER, RS232c interfaces are used for the component automatic sorting system, which provides the conditions for computer telecommunication and test recording. Flexible frequency-response analysis:Due to non-ideal inductor, capacitor and resistor, in order to precisely evaluate the characteristics of one component in one frequency band, MCH2816 could use its signal generation ability with 10mHz resolution to correctly analyze frequency response of the component parameters in any frequency band. In particular, it can do the precise measuring of the resonant impedance of the low-frequency ceramic resonant devices which has wide impedance range.
