Specification of Accessory

Re-use of Measured Data

Introduction Section

This application re-uses data collected on a similar device. The subject device (Model: XT2423-3, FCC ID: IHDT56AP2) is electrically identical to the reference device (Model: XT2423-1, FCC ID: IHDT56AP1) for the portions of the circuitry corresponding to the data being re-used. Based on their similarity, the FCC Part 15C (equipment class: DTS, DSS) and FCC Part 15E (equipment class: NII) and FCC Part 22, 24, 27 (equipment class: PCE) reuse the original model's result and include spot-checks, following the FCC KDB 484596 D01 Referencing Test Data v02r01.

The applicant takes full responsibility that the test data as referenced in this report represent compliance for this FCC ID: IHDT56AP2.

Model Difference Information

The main differences between FCC ID: IHDT56AP2 and FCC ID: IHDT56AP1 (Model: XT2423-1) are:

• Removal of WCDMA Band IV, LTE B4/13/26/66.
• Addition of NFC function, LTE B20/41.

Other differences and details of similarity/difference can be found in the confidential documents (XT2423-3_Operational Description of Product Equality Declaration).

Reference Detail Section

Spot Check Verification Data Section

Conducted power test and radiated spurious emission test against the variant model were performed based on the worst-case condition from the original model to demonstrate that the test data from the original model remains representative for the variant model. All test procedures followed the related section of the parent report.

For any given test, the maximum identified difference between spot check and reference data shall be no larger than 25%, in linear units.

The formula used is: |spot check data – reference data| / |reference data| ≤ 0.25, where "|" denotes the absolute value of the measured quantity.

Summary for Power and RSE Spot Check

Conducted Power (dBm)

For example: BT BR/EDR (dBm): mW = 10^(dBm/10). Difference = |spot check data – reference data| / |reference data| = |10^(11.49/10) - 10^(11.75/10)| / |10^(11.75/10)| = 0.058

Radiated Spurious Emission

Remark: The ECR was approved by FCC, although the RSE difference exceeds the 0.25 limit.

Conclusion

Radiated spurious emission tests against the variant model, based on the worst-case condition from the original model, were performed to demonstrate that the test data from the original model remains representative for the variant model. The power level and RSE spot checks are shown within expected levels compliant to the limit line.

Power and ERP/EIRP measurements from the original parent model reports are used for the grant.

The same DFS detection is used in the variant; therefore, there is no spot check data for DFS.

We confirm that the test data reuse policy of FCC KDB 484596 D01 Referencing Test Data v02r01 has been followed, and the test data referenced from the parent model report represents compliance with the new FCC ID.
