Payload Pattern (Bluetooth)
Auto
Payload Pattern selects the test payload the demodulator expects in the analyzed burst. The RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz).-PHY Physical Layer Test Specification defines different payloads for different transmitter tests, so the pattern determines which modulation-characteristics results are meaningful for a given capture:
-
— the payload pattern is detected automatically from the demodulated bits.
-
/ — pseudo-random payloads, used for output power and in-band emissions style tests.
-
— the repeating four-ones/four-zeros payload used to measure the Δf1 frequency deviation (RF-PHY Test Spec §4.6.3).
-
— the alternating payload used to measure the Δf2 frequency deviation.
-
— the all-ones payload used for modulation-characteristics tests of the LE Coded PHY with S=8 coding.
