The invention provides a crystal oscillator phase noise vibration monitoring device and method and solves the problem that working condition of a product cannot be truly reflected under a vibration environment in a conventional vibration test method. The monitoring device comprises a base, a monitoring plate, a fixation plate and a cover plate. The monitoring plate is clamped between the base andthe fixation plate; the fixation plate is provided with an opening and an electrode; the cover plate covers on the upper surface of the opening and is used for fixing a crystal oscillator; the monitoring plate comprises a movable connector and a printed circuit line; the movable connector is used for installing the crystal oscillator and comprises a power supply end and an oscillation signal output end; and the printed circuit line is used for connecting the oscillation signal output end and the electrode. The invention also discloses a monitoring method. The scheme realizes batch monitoring of phase noise of the crystal oscillators under a dynamic work state.
Description
technical field [0001] The present application relates to the field of electronic circuit testing, in particular to a testing device and method for crystal oscillator phase noise. Background technique [0002] In order to realize the requirements for the crystal oscillator vibration phase noise index, it is necessary to dynamically monitor the crystal oscillator vibration phase noise index. The traditional assessment method for phase noise testing of crystal oscillators is to rigidly fix the crystal components on the test bench with corresponding fixtures, and conduct environmental tests according to the spectral shape, magnitude, time and tolerance specified in the test conditions. The phase noise before and after the test was compared. The traditional vibration fixture only plays a fixed role, and such a test method cannot reflect the actual working state of crystal components in vibration. Therefore, it is impossible to observe the degree of phase noise deterioration of...
