Antenna delay

The following command has been marked as deprecated in 2110a:
set service ptp instance <instance-number> antenna-delay <antenna-delay>
Antenna delay is now configured with the new command:
set service gnss instance [N] antenna-delay [0-25000]
The antenna delay is a number in nanoseconds. It defaults to 0 nanoseconds.

This command is typically used to compensate for the antenna cable length or processing delays associated with signal distribution networks. A typical calculation would be cable length × velocity factor of the cable = antenna-delay.

This command is preferred to the deprecated command, which only compensates PTP and not the entire timing subsystem, which includes PTP.
