Page - 16 Revision 2.2 OPERATION
The “10MHz” and “Internal” global phase settings are reset to zero at startup.
This is done because no phasing information is supplied in these reference
modes and the phase of the outputs will be random when the unit is restarted.
Once enabled, the global phase offset can be specified in milliseconds, microseconds, and
nanoseconds. The global phase offset is applied before the individual phase controls for each output.
Refer to Table 2-1 for a list of all the outputs affected and the minimum phasing resolution for each. The
outputs unaffected by global phase will remain locked to the reference. The Global Phasing menu in the
OUTPUT root menu is used to configure global phase.
