GEV Timestamp Tick Frequency

The GigE Vision (GEV) timestamp tick frequency feature gets the frequency, in Hz, of the camera's internal clock that increments the GEV timestamp value. For instance, a value of 150000000 (150 MHz) means each increment of the timestamp value corresponds to a time interval of 1/150,000,000 second, or approximately 6.67 nanoseconds.

Because the value is 64 bits, the camera stores it in the registers for the GevTimestampTickFrequencyHigh and GevTimestampTickFrequencyLow nodes.

Note: The value of this feature is influenced by the PTP mode.

GevTimestampTickFrequencyHigh and GevTimestampTickFrequencyLow nodes

• Access mode: Read Only
• Node type: Uint32

You can use the eSDK API functions to get the node’s value.
