Crystals are one of the most important components of electronic devices and machines. They can store and transfer information, control the frequency of signals, and convert electrical energy into mechanical energy. A wide variety of crystals are available for many applications, including oscillators, filters, sound transducers, and special-purpose transducers. MP050 is a high-precision instrument used to measure frequency and reactance of crystals. This article will discuss the application fields and working principle of the MP050.

The MP050 can measure and analyze the resonance characteristics of crystals under different external conditions or resonant circuits. The instrument is widely used in the research and production of quartz pressure sensors, quartz heating elements, high-power transistors, filters, and vibration components. It can also be used in the development of communication products such as crystals, oscillators, and single-chip microcomputers.

The working principle of MP050 is based on the impedance matching and loop resonance method. The device consists of a signal generator, impedance matching network, series resonant circuit, frequency control circuit, and a DC bias circuit. The signal generator provides the signal to be injected into the resonant circuit. The frequency of the signal can be accurately adjusted by the frequency control circuit. The impedance matching network and the series resonant circuit form a loop, and the resonance frequency of the loop are tuned to the frequency of the signal. The DC bias circuit compromises tuning accuracy; it is used to adjust the resonance frequency or the damping of the resonant circuit. When a signal of the same frequency is injected into the resonant circuit, a voltage standing wave ratio (VSWR) of 1:1 will be generated. The MP050 instrument can measure the VSWR, and calculate the resonance frequency and quality factor of the crystal in the resonant circuit.

In conclusion, the MP050 is a versatile necessary tool for research and production in the area of crystals. It is based on the impedance matching and resonance loop method, and its accuracy can be improved by the DC bias circuit. Additionally, it is used to measure and analyze resonance characteristics, as well as to calculate the resonance frequency and quality factor of the crystal. The MP050 instrument is an effective solution for a variety of applications and crystal research.
