Df2 Rate (Bluetooth)
This result reports the percentage of measured Δf2max values that exceed the minimum deviation required by the standard. The floor depends on the PHY Physical Layer — for example, 185 kHz kiloHertz: A radio frequency measurement (one kilohertz = one thousand cycles per second). for LE 1M and 370 kHz for LE 2M (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 Test Specification §4.6.3); the corresponding BR requirement is 115 kHz.
The pass criterion is that at least 99.9% of all Δf2max values, pooled over at least 10 packets, exceed the floor. Read the pooled figure from the column with averaging ON.
