Abstract

The invention discloses a synchronizing system compatible with various clocks and a synchronizing method thereof. The synchronizing system comprises an external clock matching and amplifying unit and other units. The external clock matching and amplifying unit is connected with a first multivibrator 10MHz frequency-selecting unit and a clock driving unit, a first 10MHz band-pass filter amplifying unit is connected with the first multivibrator 10MHz frequency-selecting unit and an internal and external reference clock selecting unit, a internal time base signal generating unit is connected with a second multivibrator 10MHz frequency-selecting unit, a second 0MHz band-pass filter amplifying unit is connected with connected with the second multivibrator 10MHz frequency-selecting unit and the internal and external reference clock selecting unit, and the clock driving unit is connected with a control unit and the internal and external reference clock selecting unit. The synchronizing system can be compatible with various 1MHz, 2MHz, 5MHz and 10MHz clock inputs, provides a 10MHz clock output and can select 1MHz, 2MHz, 5MHzclock outputs according to external input clock frequency to solve the problem that different clock frequencies cannot be synchronized.

Description

technical field [0001] The invention relates to a synchronization system, in particular to a synchronization system compatible with multiple clocks and a synchronization method thereof. Background technique [0002] With the development of testing technology, there are more and more cases where various measuring instruments are used together, and there are more and more cases where various measuring instruments are used to build test systems for testing. In order to ensure the accuracy and accuracy of measurement, eliminate Due to the measurement error introduced by the clock asynchrony of each measuring instrument, it is often necessary to synchronize the clock signals of the measuring instruments used. However, due to the different standard clock frequencies selected by various instrument manufacturers, the output clock signals they provide are also different. For example, some provide 1MHz clock output, some provide 5MHz clock output, and some provide 10MHz clock output. ...
