Min Df2 Max (Bluetooth)
The Δf2 measurement divides the 10101010 test payload into its consecutive 8-bit pattern groups and finds the maximum frequency deviation within each group (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). reports the smallest of those per-group maxima, and Df2 Max reports the largest.
The number of groups the measurement found is reported as above the results grid. When no complete group was measured, this result reads rather than zero.
The specification defines no limit for this result on any PHY rate, so its cell in the Limits Table is always blank and its cell always reads . Because it is an extreme rather than a mean, its column in the Results Table is also always ; the and columns accumulate normally.
To produce this result, transmit the Df2 payload and set Payload Pattern to or .
