Measurements were performed at the lowest, middle and highest channels of the operating band. The EUT was set to maximum power level during all tests and at the beginning of each test the battery was fully charged. The DASY4 system measures power drift during SAR testing by comparing e-field in the same location at the beginning and at the end of measurement. Report File No. : F690501/RF-SAR001875-A1 Date of Issue : 2010-07-15 Page : 5 / 67 1.7 EVALUATION PROCEDURES - Power Reference Measurement Procedures The Power Reference Measurement and Power Drift Measurements are for monitoring the power drift of the device under test in the batch process. The Minimum distance of probe sensors to surface determines the closest measurement point to phantom surface. The minimum distance of probe sensors to surface is 4 mm. This distance cannot be smaller than the Distance of sensor calibration points to probe tip as defined in the probe properties (for example, 2.7 mm for an ET3DV6 probe type). - The entire evaluation of the spatial peak values is performed within the Post-processing engine (SEMCAD). The system always gives the maximum values for the 1 g and 10 g cubes. The algorithm to find the cube with highest averaged SAR is divided into the following stages: 1. The extraction of the measured data (grid and values) from the Zoom Scan. 2. The calculation of the SAR value at every measurement point based on all stored data (A/D values and measurement parameters) 3. The generation of a high-resolution mesh within the measured volume 4. The interpolation of all measured values from the measurement grid to the high-resolution grid 5. The extrapolation of the entire 3-D field distribution to the phantom surface over the distance from sensor to surface 6. The calculation of the averaged SAR within masses of 1 g and 10 g. The probe is calibrated at the center of the dipole sensors that is located 1 to 2.7 mm away from the probe tip. During measurements, the probe stops shortly above the phantom surface, depending on the probe and the surface detecting system. Both distances are included as parameters in the probe configuration file. The software always knows exactly how far away the measured point is from the surface. As the probe cannot directly measure at the surface, the values between the deepest measured point and the surface must be extrapolated. The angle between the probe axis and the surface normal line is less than 30 degree. In the Area Scan, the gradient of the interpolation function is evaluated to find all the extreme of the SAR distribution. The uncertainty on the locations of the extreme is less than 1/20 of the grid size. Only local maximum within –2 dB of the global maximum are searched and passed for the Cube Scan measurement. In the Cube Scan, the interpolation function is used to extrapolate the Peak SAR from the lowest measurement points to the i…

Information about the FHSS characteristics: 1.5.1. Pseudorandom Frequency Hopping Sequence The channel is represented by a 4 frequency hopping sequence hopping through the 16 RF channels. The channel is divided into time slots where each slot corresponds to an RF hop frequency. Consecutive hops correspond to different RF hop frequencies. The nominal hop rate is 325 hops/s. 1.5.2. Equal Hopping Frequency Use There are two modes in DLT 100 operation and which have different frequency table.
