The test set supports to precisely (within +/-50 ns accuracy) synchronize its CDMA2000 system time to an external trigger. This feature allows the test set to synchronize itself with an external device such as an Keysight ESG signal source, or another test set, to perform various tests.
There is no front panel menu or button to set the test set' s CDMA system time on external trigger. Instead, you can use the GPIB command: CALL:CELL:CSTime:TOETrigger . When this operation is successfully made, the test set sets its CDMA system time to the time you specified exactly at the time when the external trigger comes. If the CDMA system time is successfully set on the test set, the external trigger is no longer useful.
This is a single-time operation. The time synchronization keeps until something happens to break the synchronization (see Operating Consideration ).
You can also use Multi-unit Synchronization to synchronize among test sets.
