WY2853D digital display meterDetailed product description：

The WY2853D digital Q meter (50kHz-150MHz) is a high-frequency impedance measurement instrument based on the principle of series resonance, which measures the effective inductance, Q value, capacitance value, and ε, tan δ of inductors, capacitors, insulation materials, etc. at high frequencies. The WY2853D digital Q meter has been intelligently digitized based on the original WY2853 Q meter, expanding the measurement range and improving the long service life of the mechanical structure. This Q meter follows the national metrological verification regulations: "JJF1073-2000 High Frequency Q Meter Calibration Specification".

One characteristic:
Our company's innovative automatic Q-value reading technology greatly improves the accuracy and speed of Q-measurement.
DPLL synthesis generates test signals, with digital settings and continuous adjustment of signal frequency.
◎ Tune the residual inductance of the circuit to 8nH to ensure minimal error in directly reading the Q value at high frequencies.
Specially designed LCD screen with menu style display of multiple parameters: Q value, test frequency, tuning status, etc.
◎ Q-value range automatic/manual range control.
Digital Q-value preset can improve the reliability and speed of batch testing.
◎ Independent 50kHz~150MHz signal source output port, so this machine is also a 150MHz synthetic signal source, with frequency accuracy of ± 50ppm and stability of ± 10ppm.
