| Description: | Returns the minimum df1max of the acquired signal. This value is expressed in Hz. The Bluetooth test specification document specifies 11110000 as the 8-bit sequence pattern to use as a payload for this measurement. For LE-LR-125k packets, the payload pattern should be 11111111, which results in a coded bit sequence of 11110000. The toolkit measures the average frequency deviation, df1max, within the bit period for each second, third, sixth, and seventh of these 8-bit sequences. All the df1max values within a packet are recorded as block df1max. The minimum of all these values over the different acquisitions is given as Minimum df1max. 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. Assume that the toolkit returns a measurement array of N samples of block df1max in each acquisition. The toolkit does the following tasks: 1. Minimum hold averaging is done on this measurement array over the number of acquisitions specified by the NIBTSA_DF1_NUMBER_OF_AVERAGES attribute. 2. Finds the minimum of all the N samples in the measurement array obtained in step 1. Get Function: niBTSA_DF1GetMinimumdf1max |
