1.6 Specifications
The specifications listed below apply to the SecureSync standard model, i.e. not
including any option cards, and are based on “normal” operation, with
SecureSync synchronized to valid Time and 1PPS input references (in the case of
GNSS input, this is with the GNSS receiver operating in Stationary mode).
Specifications for the available option cards are provided in their corresponding
topics;see "Option Cards Overview" on page17.
