Crystal used to maintain the operating frequency of the clock. If the signal from this clock stops, or is low, or pulses begin to vary, the electronic devices that can see errors or stop completely in May. The microprocessor-Pins that hold the glass is often referred to CSOs and CSOs as shown in Figure 1 and frequency marked on the glass. Typical examples of crystal oscillator frequency is 3.58MHz, 4MHz, 8MHz Tests so 24MHZ Crystal
crystals are very fragile, because part of its construction. Unlike the opposition or a capacitor, if it falls on the ground at a decent height, its 50-50 bet whether it will work again. Testing the crystal is not child's play. You can not get their faithful multimeter and plug it into the glass. In fact, there are three ways to test a crystal: - (a) The use of an oscilloscope
glass produces a sine wave to pass. It should then see a wave form of a representative of the wave on the clock pin. If the clock does not replace the glass. In most cases, to resolve the problem, since the microprocessors are generally very reliable. Check the glass with the power. (b) Frequency
against frequencies that can be used to control the frequency of the crystal. The reading will be made when the computer is able to activate it. Place the probe against rate pin glass and read the measure. Make sure the meter has the frequency range higher than the crystal frequency to measure. (c) Crystal Checker
With this method, the glass is usually placed on the information network of a transistor oscillator. If the series and the light is light, meaning that works of glass. If the crystal does not work, the light remains outside. Instead of using LED, the second inspection through a glass panel meter to indicate if the crystal is or not.
