The present invention relates to an automatic current test and analysis
system for a constant temperature
crystal oscillator. The
system includes: 1) a multi-channel oscillator
test board, 2) a program-controlled
ammeter, 3) a multi-channel switching device, and 4) a
computer control system; the method steps: 1) Set the test standard for this current
test analysis; 2) Add a
crystal oscillator to a multi-channel oscillator
test board; 3) Check whether there is an abnormal
crystal oscillator current, 4) Start the formal test; 5) Test the
crystal oscillator 6) After testing the first
crystal oscillator, make the first
crystal oscillator enter the power-on
stable state, and at the same
time switch the
ammeter to test the second crystal oscillator, repeat step 5) until the final test Start-up current of one crystal oscillator; 7) Measure the steady current of all crystal oscillators. Compared with the prior art, the present invention has the following beneficial effects: reducing manpower use during testing and reducing
data human errors. Improve the current
test efficiency of OCXO, use only one current test instrument, achieve the speed of multiple test instruments, and reduce equipment investment.
