Parts and names
Front
- Power indicator LED
After turning on the power switch, the power indicator LED will flash. Once the startup is complete, it will become steady on. - Preheat indicator LED
When the clock generator is warming up, the indicator LED will flash. Once the warm-up is complete, it will become steady on.
Rear
- Clock output
10MHz clock output
50
impedance - Calibration signal input
Note: This calibration signal input is for use only during factory calibration.
Customers do not need to perform calibration. - Power switch
To completely disconnect the power from the device, please turn off this switch. - Power input
Please use a power cable which includes an earth wire and ensure you have a reliable earth wire connection. Otherwise, the casing of the device may have a slightly charged touch.
Connection and Use
Connection
Use a 50-ohms impedance coaxial cable to connect the device to the external equipment requiring a clock signal. The clock signal output by the device is a sine wave or square wave with a 50-ohm impedance. The waveform is set during factory calibration and cannot be changed by the customer.
The four clock outputs are synchronized with each other, and each clock output has its own independent output buffer.
Using
The device uses a temperature-controlled chamber to provide a relatively stable operating environment for the crystal oscillator. After powering on, the temperature-controlled chamber will be heat up gradually. During this process,the preheat indicator LED will flash. Once the preheating is complete, the indicator will become steady on. The preheating time may vary depending on the ambient temperature, and it takes approximately 5 minutes to complete the preheating when starting from a cold state.
The clock signal is already being output during the preheating process. Once the preheating is complete, the clock signal reaches optimal state.
Note
Please use the device in an indoor environment. Do not apply any external active cooling or heating measures. Additional cooling or heating may cause a decrease in the temperature stability of the temperature-controlled chamber,which could negatively affect the accuracy of the clock output.
It is recommended to keep the device in a continuous power-on state to reduce the preheating time during use.
