1.3. Procedure for changing configuration parameters
The configuration parameters of the transmitter can be defined in the "INSTALLATION PARAMETERS
Level 1" window and "TRANSMITTER INTERFACE INSTALLATION PARAMETERS" window of the
PCL in installation mode.
The configuration parameters of the ADAPT exciter can be defined in the "ADAPT INSTALLATION
PARAMETERS" window of the PCL.
Nota :
âŚ
MODAP Version only
To set up a new parameter configuration of the modulator, the three corrections (ALE, LUT and OLDC) should be
set to the FIXED mode. The control keys can be defined in the "MISCELLANEOUS" windows and "CONTROL
MAINT Level 4" windows.
Information contained is this document is confidential, is THOMSON property and cannot be disclosed in whatever form without prior written authorization of THOMSON.
âŚ
SIRIUS Version only
To set up a new parameter configuration of the modulator, the two corrections (ALE, and LUT) should be set to
the FIXED mode. The control keys can be defined in the "MISCELLANEOUS" windows.
The configuration parameters of the ETHERNET can be defined in the "ETHERNET INSTALLATION
PARAMETERS" window of the PCL.
DVB-T Transmitter configuration only:
⌠The configuration parameters of the COFDM can be defined in the "COFDM PARAMETTERS "
window of the PCL in maintenance MODE.
⌠The configuration parameters of the SFN can be defined in the "COFDM PARAMETERS" window
of the PCL in maintenance MODE.
DVB-T/H Transmitter configuration only:
⌠The configuration parameters of the COFDM can be defined in the "COFDM PARAMETTERS "
window and "DVB-H PARAMETTERS " window of the PCL in maintenance MODE.
MediaFLO Transmitter configuration only:
⌠The configuration parameters of the MediaFLO can be defined in the "FLO 1 PARAMETTERS"
window and " FLO 2 PARAMETTERS " window of the PCL in maintenance MODE.
The transmitter is configured in the:
⌠"INSTALLATION PARAMETERS Level 1",
⌠"TRANSMITTER INTERFACE INSTALLATION PARAMETERS",
⌠"ADAPT INSTALLATION PARAMETERS",
⌠"ETHERNET INSTALLATION PARAMETERS",
⌠"COFDM and SFN PARAMETERS" (if internal modulator) windows or "8VSB PARAMETERS"
windows or "FLO PARAMETERS" windows of the PCL.

Level 1" window
Information contained is this document is confidential, is THOMSON property and cannot be disclosed in whatever form without prior written authorization of THOMSON.
Changing a
parameter:
RESULT
Set switch SW1, situated in ⌠The transmitter is switched to installation mode.
the
exciter/CPU
interconnection card on the ⌠The "INSTALLATION PARAMETERS Level 1"
window appears on the PCL and displays the
side of the sub-units behind
current transmitter configuration parameters.
the CPU card, such that the
dot is visible.
âŚ
Press reset button in front of CPU board.
âŚ
Press on the control keys corresponding âŚ
to the parameter to be changed and then

1.6.11. Procedures for changing quality thresholds
The quality threshold is the maximum permissible deviation (in dB) from a set point before the
occurrence of a major fault (overall quality assessment of 13/20), which produces a transmitter
changeover in an N+1 or Passive Reserve system. In SD or DD systems, no changeover is
performed.
⌠The set point (Shoulder, Ripple) is the parameter threshold beyond which the ADAPT exciter
performs a correction. The set points can be defined in the "CONTROL MAINT Level 3" window.
⌠The power set point is the calibrated RF power of the transmitter, it is fixed and is available to the
operator in the "INSTALLATION PARAMETERS Level 1" window.
Information contained is this document is confidential, is THOMSON property and cannot be disclosed in whatever form without prior written authorization of THOMSON.
