4.1.1.2 Pattern Data Generator

The pattern generator generates the following data:

  • 32-bit Ethernet data: The16-bit of MSB is constant and 16-bit of LSB is incremental data.
    Figure 4-3. Ethernet Data Pattern
  • 32-bit VSS data: The 16-bit of MSB is constant and the16-bit of LSB is incremental data.
    Figure 4-4. VSS Data Pattern
  • 32-bit Antenna Carrier Control data: The 16-bit of MSB is constant and the 16-bit of LSB is incremental data.
    Figure 4-5. Antenna Carrier Data Pattern
  • In this demo four Antenna carriers are used, each antenna generates 32-bit data. The IQ data samples of each Antenna carrier control are fixed at 15-bit. The user-interface width is fixed at 32-bit, with zero appending on MSB. 15-bit IQ data samples are bit-stuffed in the 32-bit user interface for each Antenna carrier.
