[0019] The present invention will be further explained below in conjunction with the drawings.
[0020] Such as figure 1 As shown, the whole set of equipment is divided into two main total scores: test cabinet and high and low temperature box. The test cabinet is mainly a carrier, and the total scores of the equipment are installed inside. The test cabinet is the core of the whole set of measurement equipment, including high-power linear power supply, frequency measuring instrument, industrial computer and frequency transmission conversion module.
[0021] The high-power linear power supply is electrically connected to the crystal oscillator test board through the power cord to provide power for the crystal oscillator. The power supply is required to have a stable voltage and sufficient current. Due to the large number of simultaneous measurements and the large current of a single OCXO, the power requirements are high. Multiple crystal oscillator test boards can be placed in the ...
