Edit-Unit-Clocks-Station Clock Use Screen
Options:
Replace internal 10MHz clock
Do not replace 10MHz clock
Factory default:
Replace internal 10MHz clock
Description:
Controls the function of the station clock i.e. whether it replaces the
internal 10MHz reference clock or not (which is used as the main clock
for the modem’s internal processing). Note that the decision on whether
to use the station clock for Tx and/or Rx clocking purposes is controlled
by the Tx and Rx clock source menu options (under
Edit/Tx/Clocks
and
Edit/Rx/Clocks
) – these options become available when a station clock
source is selected and are independent of whether station clock replaces
the internal 10MHz clock.
Edit-Unit-Clocks-Station Clock Frequency Screen
Units:
kHz
Minimum value:
1
Maximum value:
10000
Step size:
1
Factory default:
10000
Description:
Indicates to the modem the frequency of the station clock input reference
used for Tx and Rx clocking purposes. If the station clock is being used
to replace the internal 10MHz reference then this screen is not shown as
the station clock must provide exactly 10MHz in this case.
Station clock use:
[Replace internal 10MHz clock]
New: Replace internal 10MHz clock
Station clock freq:1000 to 10000kHz
[1000] Step 1kHz
New: 10000
