Precaution:
- If the height is not suitable, the height can be adjusted appropriately by adding or reducing shims;
- When using, it is necessary to fix the circuit board to prevent poor contact;
- When adjusting the potentiometer, be sure to fix the circuit board properly, otherwise it may cause poor contact and significant frequency fluctuations.
FAQ:
Q: What should I do if the green light on the circuit board does not light up after power on?
A: Check if the power supply is plugged in properly and if the power supply is sufficient. It is recommended to use a 15V 3A power supply (not included). If the power supply is normal, it may be a malfunction of the rubidium clock. It is recommended to check the rubidium clock.
Q: After powering on, the green light is on, while the red light remains on and cannot be extinguished. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.
Q: Just powered on, the green light and the red light is on. After a while, the red light goes out, and after a while, the red light on again. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.
Q: Just powered on, the green light and the red light is on, and after a while, the red light becomes dim, but it doesn't go out. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.
Q: Just powered on, the green light is on, but the red light remains off. What should I do?
A: The rubidium clock is malfunctioning. It is recommended to check the rubidium clock.
Q: After connecting the potentiometer, no matter how the potentiometer is adjusted, the frequency cannot be adjusted to 10M
A: The rubidium clock needs to be adjusted or has a malfunction. It is recommended to check the rubidium clock.
Q: After connecting to SMA, why cannot check the 10M output?
A: Check if the SMA interface has good contact. If contact well, there is a possibility of rubidium clock malfunction. It is recommended to check the rubidium clock.
