Resonators are electromechanical devices that are used in various applications, many of which involve the measurement of frequency and the production of a harmonic signal. The ASR 4188-T resonator is one such device, which is used in a number of different kinds of applications and it has several advantages over other types of resonators.The ASR 4188-T is a voltage tuning type resonator. It is designed to be used in applications such as oscillators, frequency synthesizers, filters, and frequency generators. The resonator is constructed from a piezoelectric quartz crystal and a stainless steel body. The crystal is animated by an alternating electrical current, which causes it to vibrate at a certain frequency. This frequency can be adjusted by changing the supply voltage.The main advantage of the ASR 4188-T is its precision and repeatability. It is capable of maintaining a frequency within ±2 parts per million from zero to over 10MHz, making it an ideal device for precision applications. Additionally, it is also able to maintain a frequency range of 15 microHit or lower, eliminating the need for costly frequency calibrations.Another advantage of the ASR 4188-T is its low power consumption. The resonator requires only 1.2vdc of supply voltage and consumes less than 50mA of current, making it extremely energy efficient. Additionally, the device can run for up to 40 hours on a single charge, meaning there is no need for frequent battery changes.The working principle of the ASR 4188-T resonator is quite simple. It consists of two parts--the piezoelectric quartz crystal and the stainless steel body. The quartz crystal is acting as a capacitor in the resonator and when it is connected to the AC power source a small amount of energy is stored in the quartz crystal. The frequency at which this energy is stored is determined by the voltage of the AC supply. The resonator acts as a frequency tuning device, where the frequency output is a function of the input voltage.The ASR 4188-T resonator is a versatile device and is used in several different applications. It can be used in frequency synthesizers and oscillators, filters, and frequency generators. The device can also be used in medical instrumentation and telecommunication systems, where its high precision and accuracy makes it an invaluable tool.In conclusion, the ASR 4188-T is a highly versatile and precise device, which is well suited for a variety of applications. It is capable of maintaining a frequency range and accuracy that is superior to many other types of resonators. Furthermore, its low power consumption and long battery life make it a more economical choice for many applications.
