Burst Table (Bluetooth)

The Burst Table trace lists every Bluetooth burst detected within the Search Length, one row per burst, with its position and length in the acquisition.

The burst analyzed by the demodulator — and used for all results and demod traces — is selected with the Burst parameter on the Time tab. Use this table to confirm that the expected burst was found and to choose which burst to analyze when the search length contains several.

The table has one row per burst, numbered from 1 in the order the bursts occur, and these columns:

Column

Reports

SNR (dB)

Signal-to-noise ratio estimated for the burst.

Packet Type

The packet type detected for this burst when Packet Type is Auto: Advertising, Data or Test. It reads Unknown when the burst was found but matched no candidate access address, and - when the packet type was declared rather than detected.

Sync

Yes when the burst synchronized, No when it did not.

CRC

PASS or FAIL for the decoded payload, or -- when the CRC Cyclic Redundancy Check was not checked.

Limits

The limit verdict for this burst: PASS, FAIL, or *** when nothing was measured on it.

Pattern

The payload pattern measured in this burst — for example PRBS9, 11110000 (Df1) or 01010101 (Df2). This is what was detected, not what was requested, and it reads Unknown when no pattern was recognized.

Payload (octets)

Decoded payload length. Blank when the payload did not decode.

Start (s)

Position of the burst in the acquisition.

Length (s)

Duration of the burst.

 

The table lists at most 16 bursts. Bursts detected beyond the sixteenth are analyzed but not tabled.
