Display LED Explanation
Sum Fault F Sum Fault: One or more errors occurred
RF On RF level at the exciter output is OK
F There is no RF level at the exciter output even though the RF
output is enabled
- OFF - No RF level at output of exciter since the RF output is not
enabled (manual disabling)
Exciter On RF output of the exciter is enabled
There are several ways of enabling the RF output:
– using the setting item RF Output in the RF Out > Output
menu
– on the front panel of the instrument via the RF ON/OFF key
Mute W RF signal is disabled by the signal processing unit in the exciter
Input Ok Valid transport stream present at active input
In the case of hierarchical coding, the input is OK if valid trans-
port streams are present at both inputs (for HP stream and LP
stream).
W Invalid transport stream at active input (combined with the setting
Type of Loss of Input = Warning, see section "Exciter > Input >
Input Automatic")
F Invalid transport stream at active input (combined with the setting
Type of Loss of Input = Fault, see section "Exciter > Input >
Input Automatic")
Fifo W Overflow or underflow of the input buffer due to incorrectly con-
figured DVB transmission parameters. Possible reasons:
– incorrect data rate of the input data stream
– excessive fluctuations in the input data rate (bursts)
