Df1 Max (Bluetooth)
(Δf1max) is the maximum frequency deviation measured while the transmitter sends the repeating 11110000 test payload (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). Four consecutive identical bits give the modulation time to reach its full deviation, so Δf1 characterizes the peak deviation of the GFSK Gaussian frequency shift key: A modulation scheme in which the data is first filtered by a Gaussian filter in the baseband and then modulated with a simple frequency modulation. modulator.
The result is computed within the analyzed burst. To produce this result, transmit the Df1 payload and set Payload Pattern to or .
