To edit the clock module configuration:
Select the mode in the Clock Mode drop-down box. Clock mode options are Acquire, Locked, Holdover or Warmup.
Select the TAU value in the PTau drop-down box. The Tau value indicates how long data is averaged (in seconds) to compute the output frequency control loop.
Select ON or OFF in the Auto Return drop-down box. ON allows the system to return to the previous port if a better signal becomes available.
Enter a control value, if needed, in the CV drop-down box.
Note: To set the TSG-3800's control value ( CV), the system must be in holdover mode. You will typically set the CV to zero. Setting the CV to zero removes a frequency offset in the local oscillator that is typically caused by a poor input reference. Ensure the frequency stability and quality of the input reference before setting the control value.
Click OK to accept changes and return to the Clock Module screen, or Cancel to return to the Clock Module screen without saving changes.
