10MHz refer. (Int, Ext, ASI)
This parameter shows the 10MHz reference source selection set by the user (Int, Ext, ASI). In
case it is Ext or ASI and if the chosen reference is absent, the modulator automatically uses the
internal reference. This is shown in parentheses. By clicking on this item, the user can change the
10MHz reference source. (See the Synchronization and Clocks paragraph for more
information about the input reference stage of the modulator).
10MHz input (Present, Absent)
This is a read-only parameter that indicates the presence or absence of the external 10MHz
reference. (See the Synchronization and Clocks paragraph for more information about
the input reference stage of the modulator).
LoR Mute (ON, OFF)
When the external reference is absent, it is possible to automatically mute the output after
a configurable timeout. By choosing ON, the automatic mute on lost of reference feature is
enabled. Set this parameter to OFF to not mute the output on lost of reference.
LoR Timeout (00h00’-24h00)
It’s the timeout the transmitter waits before muting the output on lost of reference. If the
LoR Mute parameter is OFF, the timeout is ignored. Set the timeout to 0 to immediately
mute the output on lost of reference.
