If the ATS-6501 is able to communicate with the clock for monitoring (i.e. type=hp5071A) the
operator will provide the communications method (serial | ip) and the physical address of the
clock (/dev/xxx) or (XXX.XXX.XXX.XXX:PORT#). Ethernet monitoring of the clock is
provided to enable use of a clock as a reference for multiple ATS 6501s. An external serial to
Ethernet converter must be used to utilize this feature. Each clock set up for monitoring will be
periodically polled to ensure the clock is functioning properly while operating with the ATS-
6501. No steering of the external clock is performed by the ATS-6501.
The next step in setting up the system is to select one of the clocks entered using the add_clock
command to be the reference for the filter by using the timescale_filterref command
timescale_filterref Test1
