Oscillator characteristics testing method e.g. for quartz oscillator, involves applying signals with same frequency but different amplitude, to oscillator chip for multiple times, to determine conformity of oscillator

摘要

The signals with same frequencies but different amplitude, are applied multiple times from a network analyzer 6) to an oscillator chip (4) through the electrodes (2,3). The corresponding outputs of the oscillator chip are measured and stored in memory of personal computer (1). The stored results are compared so as to determine whether the oscillator chip is conforming or not conforming item.
