TesterMeter-ZC2818A precision LCR digital bridge
Description
Brief introduction
| ZC2818A high-frequency precision LCR digital bridge is an impedance measuring instrument with high measurement accuracy, wide test range, 6-bit test resolution, test frequency up to 300kHz, arbitrary programming at 0.01Hz steps, 10mV~2V signal level It can meet the requirements of production line quality assurance, incoming inspection and laboratory high-precision measurement. The HANDLER and RS232C interfaces provided by the instrument provide conditions for the instrument to be used in the automatic component sorting system, communicate with the computer and record the test process. |
Performance characteristics
240×128 dot matrix large graphic LCD display 20Hz ~ 300kHz test frequency, can be programmed arbitrarily in 0.01Hz steps 10mVrms ~ 2.0Vrms test level, arbitrary programming in 0.01V steps 30Ω, 100Ω optional signal source output impedance Open circuit, short circuit, load correction function Built-in comparator, 10 grades sorting and counting function RS232C, HANDLER interface |
Flexible frequency response analysis
| Since there are no ideal inductors, capacitors and resistors, in order to accurately evaluate the actual performance of an actual component in a certain frequency band, ZC2818A can accurately measure the frequency response of component parameters in any frequency band by virtue of its 10mHz resolution signal generation capability. The analysis, especially for the accurate measurement of the resonance impedance of low-frequency ceramic resonators with a wide impedance range. |
