Max Frequency Drift (Bluetooth)
is the maximum difference |fn − f0| between the carrier frequency measured over the packet preamble (f0) and the carrier frequency measured over successive 10-bit intervals of the payload (fn) within the same packet (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 §4.6.4).
Drift is inherently a per-packet result — Bluetooth is a frequency-hopping system, so carrier frequency is never compared between packets. Conformance requires every measured value to meet the limit; with averaging ON the worst case appears in the / columns of the Results Table.
