Displays
(*)
Left of “TP”:
Indicates “desired operating mode not yet reached”, displayed continuously in the event of an error.
If the indicator (*) is fl ashing, the channel unit cannot reach its proper operating mode.
This may be because of the following reasons (among others):
•
Input frequency or symbol rate set incorrectly
•
No input signal
Right of “Outp.”:
The channel unit output is switched off.
(!)
The exclamation mark indicates that the settings of the output symbol rate and QAM stage are not suffi cient for
processing the input data rate (i.e. the input data rate is greater than the output data rate).
•
without the programme fi lter, a defective output signal will be output
•
with the programme fi lter, the data rate can be suffi ciently reduced by fi ltering out individual programmes.
The exclamation mark indicates here that the user should check the correct operation
(P)
Just to the left of „TP“:
The „P“ indicates that the programme fi lter is activated and that some programmes may be removed from the trans-
ponder
stream.
