Guide for multi DPU Operation 3.4.13.5
CONFIGURATION
The Configuration window enables to mount and connect up to 8 DPU (Data Processing Unit) with the
DMU (Demodulation Unit A).
From the following windows examples it can be seen that the hardware menu (FPGA basic menu)
number is 5 for the test modulator and 16 for the demodulator. These menus support the multi-DPU
processing.
In the following first example, the 8 DPU and associated 8 DRU (Data Recording Unit) are enabled.
This selection corresponds to the 16QAM – 8DPU configuration.
16QAM – 8DPU Configuration
In the following second example, 4 DPU and associated 4 DRU are enabled. This selection
corresponds to the QPSK or 16QAM – 4DPU configuration.
Remark that with the 4 DPU configuration, must be selected: DPU and DRU A, C, E and G.
For the standard QPSK- 2 DPU configuration, must be selected only DPU and DRU A and C .
Only one DMU (DMU A) is available with this demodulator hardware menu number 16.
