Demodulation:DF2:Results:Maximum ICFT (Hz) Property

Short Name: DF2 Maximum ICFT (Hz)

Property of niBTAnalysis

Returns the maximum initial carrier frequency tolerance (ICFT) over different acquisitions and it is denoted by f₀ . This value is expressed in Hz.

The toolkit integrates the frequency of the FM demodulated signal from the center of the first preamble bit to the center of the first bit following the last preamble bit. For LE-LR-125k packets, the frequency integration is done from the start of the third preamble bit to the end of the 18^th preamble bit.

Refer to section 5.1.10 of the Bluetooth Test Specification Radio Frequency Test Suite Structure (TSS) and Test Purposes (TP) Specification 1.2/2.0/2.0+EDR/2.1/2.1+EDR/3.0/3.0+HS for more information about BR packets, and sections 4.6.4, 4.6.9, and 4.6.11 of Bluetooth Test Specification 5.0.0 for more information about LE packets.

The toolkit averages this measurement, using peak hold averaging, over the number of acquisitions specified by the DF2 Number of Averages property. However, the sign is retained in the result. The toolkit finds the maximum of |f₀ | over different acquisitions and adds corresponding f₀ sign to the result.
