3.2.9. Frequency references
The exciter is equipped with an internal frequency reference with stability of ± 4ppm, adequate for many
applications including multi frequency applications.
The user can either use the internal GPS receiver or an external GPS reference. The smart engine is designed to
avoid any frequency jump at RF output. The frequency reference can either be the internal GPS or external 1pps
signal or external 10MHz. When SFN is used, the pps signal is mandatory during the initialization phase.
