Working with Data Patterns

Working with Data Patterns

This section provides information on the following:

•“Using a Predefined Data Pattern” on page 148

•“Using a User-Defined Data Pattern” on page 149

•“Using an Externally Supplied Data Pattern” on page 152

The Data menu enables you to select from predefined and user defined data patterns. Data Patterns are used for transmitting continuous streams of unframed data. When the Custom Off On softkey is on, the real-time custom I/Q symbol builder creates I/Q symbols based on the data pattern and modulation type that has been selected. Refer to “Working with Modulation Types” on page 136 for information on selecting a modulation type.

The following data patterns are available:

•PN sequence allows you to access a menu (PN9, PN11, PN15, PN20, PN23) for internal data generation of pseudorandom sequences (pseudorandom noise sequences); a pseudorandom noise sequence is a periodic binary sequence approximating, in some sense, a Bernoulli “coin tossing” process with equiprobable outcomes.

•FIX4 0000 allows you to define a 4-bit repeating sequence data pattern and make it the active function. The selected 4-bit pattern will be repeated as necessary to provide a continuous stream of data.

•Other Patterns allows you to access a menu of choices (4 1’s & 4 0’s, 8 1’s & 8 0’s, 16 1’s & 16 0’s, 32 1’s & 32 0’s, or 64 1’s & 64 0’s) from which you can select a data pattern. Each pattern contains an equal number of ones and zeroes. The selected pattern will be repeated as necessary to provide a continuous stream of data.

•User File allows you to access a menu of choices from which you can create a file and store it to the Catalog of Bit Files, select from a Catalog of Bit Files and use it, or select from a Catalog of Bit Files, edit the file, and resave the file.

•Ext allows data patterns to be fed into the I/Q symbol builder, through the DATA port, in real-time.
