MEASUREMENT UNCERTAINTY TMU.2015.07.10 Measurement Uncertainty When a measurement is made, the result will be different from the true or theoretically correct value. The difference is the result of tolerances in the measurement system that cannot be completely eliminated. To the extent that technology allows us, it has been our aim to minimize this error. Measurement uncertainty is a statistical expression of measurement error qualified by a probability distribution. A measurement uncertainty estimation has been performed for each test per our internal quality document QM205.4.6. The estimation is used to compare the measured result with its "true" or theoretically correct value. The expanded measurement uncertainty (K=2) can be found included as part of the applicable test description page. Our measurement data meets or exceeds the measurement uncertainty requirements of the applicable specification; therefore, the test data can be compared directly to the specification limit to determine compliance. The calculations for estimating measurement uncertainty are based upon ETSI TR 100 028 (or CISPR 16-4-2 as applicable), and are available upon request. The following table represents the Measurement Uncertainty (MU) budgets for each of the tests that may be contained in this report.

TEST DESCRIPTION The highest gain antenna of each type to be used with the EUT was tested. The EUT was configured for the required transmit frequencies and the modes as showed in the data sheets. For each configuration, the spectrum was scanned throughout the specified range as part of the exploratory investigation of the emissions. These “pre-scans” are not included in the report. Final measurements on individual emissions were then made and included in this test report. The individual emissions from the EUT were maximized by rotating the EUT on a turntable, adjusting the position of the EUT and EUT antenna in three orthogonal axis if required, and adjusting the measurement antenna height and polarization (per ANSI C63.10). A preamp and high pass filter (and notch filter) were used for this test in order to provide sufficient measurement sensitivity. Measurements were made with the required detectors and annotated on the data for each individual point using the following annotation: QP = Quasi-Peak Detector PK = Peak Detector AV = RMS Detector Measurements were made to satisfy the specific requirements of the test specification for out of band emissions as well as the restricted band requirements. If there are no detectable emissions above the noise floor, the data included may show noise floor measurements for reference only. Measurements at the edges of the allowable band may be presented in an alternative method as provided for in the ANSI C63.10 Marker-Delta method. This method involves performing an in-band fundamental measurement followed by a screen capture of the fundamental and out-of-band emission using reduced measurement instrumentation bandwidths. The amplitude delta measured on this screen capture is applied to the fundamental emission value to show the out-of-band emission level as applied to the limit. Where the radio test software does not provide for a duty cycle at continuous transmit conditions (> 98%) and the RMS (power average) measurements were made across the on and off times of the EUT transmissions, a duty cycle correction is added to the measurements using the formula of 10*LOG(dc).

OUTPUT POWER EMC XMit 2017.12.13 Testing was performed using the mode(s) of operation and configuration(s) noted within the report. The individuals and/or the organization requesting the test provided the modes, configurations and settings used to complete the evaluation. The actual test parameters are specified in the test data, this includes items such as investigated frequency range (scanned) and test levels. The testing methods and performance specifications, as well as the test site used for the evaluation are indicated in the test data. TEST EQUIPMENT Description Manufacturer Model ID Last Cal. Cal. Due Generator - Signal Agilent E4422B TGQ 15-Mar-18 15-Mar-21 Cable ESM Cable Corp. TTBJ141 KMKM-72 MNU 15-Mar-18 15-Mar-19 Attenuator S.M. Electronics SA26B-20 RFW 13-Feb-18 13-Feb-19 Block - DC Fairview Microwave SD3379 AMI 7-Sep-18 7-Sep-19 Analyzer - Spectrum Analyzer Keysight N9010A (EXA) AFQ 19-Dec-17 19-Dec-18 TEST DESCRIPTION The measurement was made using a direct connection between the RF output of the EUT and a spectrum analyzer. The transmit frequency was set to the required channels in each band. The transmit power was set to its default maximum. Prior to measuring peak transmit power the DTS bandwidth (B) was measured. The method found in ANSI C63.10:2013 Section 11.9.1.1 was used because the RBW on the analyzer was greater than the DTS Bandwidth of the radio. De Facto EIRP Limit: The EUT meets the de facto EIRP limit of +36 dBm. Report No. RDBR0003 15/18
