| Description: | Returns the maximum df2max values of the acquired signal. This value is expressed in Hz. The Bluetooth test specification document specifies 10101010 as the 8-bit sequence pattern to use as a payload for this measurement. The toolkit measures the maximum frequency deviation, df2max, within the bit period. The array of all the df2max values within a packet is called block df2max. The maximum of all these values is taken over different acquisitions and is given as Maximum df2max. Refer to section 5.1.9 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 4.6.3, 4.6.6, 4.6.7, 4.6.8, and 4.6.10 of Bluetooth Test Specification 5.0.0 for more information about LE packets. The toolkit averages this measurement over the number of acquisitions specified by the NIBTSA_DF2_NUMBER_OF_AVERAGES attribute. Assume that the toolkit returns a measurement array of N samples of block df2max in each acquisition. The toolkit does the following tasks: 1. Peak hold averaging is done on this measurement array over the number of acquisitions specified by the NIBTSA_DF2_NUMBER_OF_AVERAGES attribute. 2. The toolkit finds the maximum of all the N samples in the measurement array obtained in step 1. Get Function: niBTSA_DF2GetMaximumdf2max |
