Configuration of the modulators
Select a
modulator
Select a modulator from MODULATOR 1 to MODULATOR 3 on the left.
Make the required changes.
Click SAVE for each modulator.
Only then the changes will be saved, otherwise the changes will be lost.

Some configuration options are dependent on each other. In this case,
selectable values are highlighted in white, non-selectable values in
grey.
The Common Output Level option include a general attenuation of all modulator outputs. The
highest output level is reached with a setting of 20 dB, the lowest level with a setting of 0 dB.
In this selection field, you can set the norm for the output channel spacing.
Note: Changing the norm works now according to following rules:
•
CCIR-->Australia : all modulators forced to 7MHz
•
Australia-->CCIR : all modulators forced to 8MHz, however with following exception: low
channels S2-S20 are 7MHz only, so those remain in 7MHz
Each of the modulators can be set to any output channel. No output channel may be selected
more than once!
The modulation can be adjusted to the following methods:
•
QPSK (2 bit) – small data rate – very robust signal.
•
QAM 16 (4 bit) – low data rate.
•
QAM 64 (6 bit) – middle data rate.
•
QAM 256 (8 bit) – high data rate.
