Df1 Avg (Bluetooth)
(Δf1avg) is the average frequency deviation measured over the 00001111 / 11110000 bit groups within the analyzed burst (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 §4.6.3, steps 1–7). The Core Specification requires 225 kHz kiloHertz: A radio frequency measurement (one kilohertz = one thousand cycles per second). ≤ Δf1avg ≤ 275 kHz for the LE 1M PHY (twice that for LE 2M).
Conformance testing repeats the measurement over at least 10 packets and averages; with averaging ON, the column of the Results Table provides this multi-packet mean. To produce this result, transmit the Df1 payload and set Payload Pattern to or .
