Creating Signals
User file format
Both modes of operation, Data Stream and Packet Generator, allow users to select
User File as the Data Pattern. This data must be in binary form. The most significant
bit (MSB) of the first byte in the user data file will be the first bit of the user payload.
The MSB of the second byte in the user file will be the ninth bit of the user payload,
and so on. An example MATLAB
®
program to generate and save user data is included
in the appendix section of this document.
User File
If User File is selected as the data pattern, the number of bits in the user’s data file will
equal the value displayed in the Pattern Length field, when the Pattern Reps field is set
to one. The number of times the pattern is repeated can by selected by entering the
desired repetition value in the Pattern Reps field. The Pattern Reps and Pattern Length
fields are coupled. If one of these fields is changed, the other field will automatically be
updated.
Packet generator mode
When operating in Packet Generator mode, the software creates fully coded, standard-
based Bluetooth packets. Table 1 provides a summary of the different packets that can be
configured using the software.
