Using an External 10 MHz Input
You can configure the NV30LT-N to accept an external 10 MHz input using the remote AUI (see External
10 MHz Input - Using the AUI ) or using the local front panel display (see External 10 MHz Input - Using
the Front Panel, on page 3.2.104 ).This setting allows the user to mask the associated 10 MHz alarm from
appearing on the
Status
page if it isn't being used
.
If an external 10 MHz source is being used, select
Yes
; this ensures that an alarm will be activated on the
Status
page should the external signal be lost. If
an external 10 MHz source is not being used, leave the default
No
setting as is. This will ensure that no
alarm will be displayed on the Status page despite the presence of the external 10 MHz signal.
NOTE
: The exciter will automatically use an external 10MHz reference signal if connected, no matter
the state of this parameter.
