No oscillator output frequency counter automatic test equipment

Crystal Oscillator Frequency counter Automatic verification

Plenary track > Automated Test and Measurement Systems

Frequency counter is an instrument for measuring frequency signal. According to whether the internal crystal oscillator is output or not, it can be divided into the oscillator output frequency counter and no oscillator output frequency counter. For the detection of non crystal oscillator output frequency counter, manual verification method is time-consuming and laborious. In order to realize automatic operation and improving the quality and the efficiency of verification, a research on design of the automatic system is carried out. On the basis of verification regulation, a automatic test equipment of no oscillator output frequency counter is designed, which can achieve automatic verification of the boot feature, frequency reproducibility and accurate frequency.
