WY2852D is a high frequency impedance measuring functioned by series resonance principle and applied to test inductors, capacitors at high frequency for their effective inductance, capacitance, Q as well as ε，tanδ values, The meter has been intelligently digitized based on WY2851,improing its measuring range and the service life of the tuning mechanical structure. It is in compliance with National Measurement and Test Regulations :“JJF1073-2000 Standard for High Frequency Q Meter ”

Features:
◎ Auto Q value reading technique of the company’s innovation which the accuracy and speed of measuring Q value by a big margin.
◎ 4 digit effective displayed, Q value 0.1Q resolution. improve the precision of measurement for tan δ.
◎ DPLL synthesized test signal ,digital set and continuously controlled signal frequency.
◎ Special LCD screen displays multi parameter like a menu: Q value, test frequency, tuning state, etc.   
◎ Q value range can be controlled both automatically and manually.
◎ Digitized Q value presetting which raises the reliability and while measuring in  batches.
◎ Separated signal source output (from 1kHz to 70MHz),the meter is also a 160MHz synthesis signal source with frequency accuracy±50ppm and stability±10ppm.
