Notes/Equations
- This model is used to generate the transport channel signal source.
This model performs the same as the Agilent signal generator instrument ESG-D Option 100. - The transport channel source serves as a bit source, the rate of which is determined by the DynTFSet parameter. The content is determined by DataPattern.
- DynTFSet consists of transport block size and transport block set size groups. The transport block set size is a multiple of transport block size. The maximum transport block set size cannot exceed 32767.
For example, if a transport channel has a transport format set:
The DynTFSet should be set as "10 20 10 40". DataOut will output 40 (the maximum transport block set size) tokens each firing. The output of TFSetSize will be 2, because it has two TFs in the set.{10 bits, 20 bits}; {10 bits, 40 bits}
TFIout can be 0 or 1 randomly; if 0, the valid output data is 20 bits long, and the remaining bits will be filled with 0; if 1, the valid output data is 40 bits long. - This model supports five patterns of data: random, PN9, PN15, fixed repeated 8-bits, and user-defined file.
If the data pattern is 8-bits repeating, the bits to be repeated is set by RepBitValue. For example if the RepBitValue is set as 0 x 7a, the bit sequence 0, 1, 1, 1, 1, 0, 1, 0 will be output repeatedly.
If the data is from user-defined file, the file name is defined by UserFileName. The designer can edit the file with any text editor. The separator between bits can be a space, comma, or any other separator. If the bit sequence is shorter than the output length, data will be output repeatedly.
