The last two columns have to be read from bottom to top:
I : 1010 0110 1001 0101 = 0xA695
n
Q : 0110 0101 1010 1001 = 0x65A9
n
Then the explicit DNRZ Code is 0xA69565A9.

Multi-DGU support

The test modulator has firmware-dependent support of multiple data sources. This enables simulation
of transmitting schemes with multiple interleaved logical data units. Here are a few examples of the
available schemes:
DGU1
Max : 1,6 Gbps
DGU2
Max : 1,6 Gbps
