# Explicit Clock

The Explicit Clock clock recovery mode lets you provide a clock from the circuit that you are measuring. This lets you make a jitter measurement with respect to the provided clock.

When the Explicit Clock clock recovery mode is selected, the dialog box has these controls:

- Symbol Rate — not used with this clock recovery method.

  The Select From List drop-down menu lets you select typical rates for standard communication interface technologies. The Auto Set Symbol Rate button runs a data rate measurement and populates the Symbol Rate field with the data rate measured on the input signal.

## Explicit Clock Settings

- Explicit Clock Source — This specifies the input source of the provided clock to be used for clock recovery.

- Edge Direction — Lets you specify the edges used in the explicit clock: Rising edges, Falling edges, or Both rising and falling edges.

- Clock Multiplier — This specifies the multiplier of the provided clock to be used.
