For testing daily frequency drift of rubidium frequency standard, the method of time difference is used, designed daily frequency drift measuring equipment for rubidium frequency standard. The device is designed by multi-divider, the measured frequency standard 1MHz, 5MHz,10MHz signal divider standard 1PPS signal. Measuring the time difference data through the GPIB interface to control the time interval counter and transmitted to a computer, to calculate the results by software. The test results show that this device has the advantages of high automation, stable. The device can meet the test requirements of measuring and testing department that several rubidium frequency standards can be measured automatically.
