9.3 Time Synchronization Accessories
9.3.1 CMGPS
You can synchronize two or more CMC test sets by connecting a CMGPS
synchronization unit to each of the test sets’ "ext. Interf." inputs. Since the
GPS (G
lobal Positioning System) signal is available worldwide, the physical
distance between these test sets is thereby of no relevance ("end to end"
testing).

For detailed information about the CMGPS, please refer to the CMGPS
reference manual, the product catalog, or the OMICRON Web site
www.omicron.at. For ordering information about the CMGPS, refer to table
9-4, "Ordering information" on page 87.
