Digital high-frequency EN_1 table (EN_2- EN_3)Detailed product description：

As the latest generation of universal, multi-purpose, and multi range impedance testing instrument, AS2853A high-frequency Q meter has a testing frequency upper limit of 160MHz, which is currently the highest in China. The AS2853A high-frequency Q-meter adopts multiple leading technologies:
Dual scan technology - dual scan and automatic tuning search function for testing frequency and tuning capacitance.
Dual test element input - both the test frequency and tuning capacitance value can be entered through digital buttons.
Dual digital tuning - digital frequency tuning, digital capacitor tuning.
Automated measurement technology - automatically measure the Q value, resonance point frequency, and capacitance of the test piece.
Full parameter LCD display - digital display of main capacitance, inductance, Q value, signal source frequency, and resonant pointer.
DDS digital direct synthesis signal source - ensuring high fidelity of the signal source, high precision of frequency, and high stability of amplitude.
Computer automatic correction technology and test circuit optimization - minimize residual inductance in the test circuit, completely eliminating the confusion of correcting Q reading values at different frequencies.
