Abstract

The invention discloses an electrical performance testing system for an oven controlled crystal oscillator. The electrical performance testing system comprises an oven controlled crystal oscillator testing device, a switching power supply group, a control computer, a frequency counter and a rubidium atomic clock. According to the electrical performance test system for the constant temperature crystal oscillator, the current, the frequency and the oscillation starting time of the constant temperature crystal oscillator can be automatically tested on a large scale, the electrical performance test of the constant temperature crystal oscillator is converted from manual test to automatic test of the test system, the working efficiency is greatly improved, and data tracing is realized.

Description

technical field [0001] The invention relates to the testing field of crystal oscillators, in particular to a large-scale constant temperature crystal oscillator electrical performance testing system. Background technique [0002] The electrical performance test of the constant temperature crystal oscillator mainly includes current test, frequency test, and start-up time test, which are currently done manually. The constant temperature crystal oscillator needs to be pre-powered during the test. After the pre-power is completed, the test is performed manually on the special test fixture one by one, and the test items also need to be carried out one by one. The test requires a large number of testers, and the indicators are all judged manually. Test data cannot be left, and information tracing and data analysis cannot be performed. [0003] In order to improve production efficiency and trace production data, the present invention proposes a constant temperature crystal oscilla...
