Creating a Test Plan - FCC LTE-CA

The FCC LTE-CA option is used for FCC / IC (ISED) certification testing of terminal products supporting LTE Carrier Aggregation.


Basic Settings

FCC_LTE-CA_overview


  • Title: Test plan name, entered by the user.


  • CC Num: Number of carriers, currently only 2 is supported. Note: changing CC Num will clear the Band Info.


  • Band Info: Select the CA band combination supported by the product (e.g., CA_2C / CA_2A-4A / CA_2A-5A). The table then lists the DL / UL rows:

    • CC: Band of each Component Carrier.

    • UL Frequency: Uplink frequency range (MHz), auto-filled.

    • Pmax: Maximum transmit power (dBm), default 23.

    • Bandwidth DL / Bandwidth UL: Bandwidths (MHz) supported by each carrier, multi-select. Available options vary with the band combination.


  • Modulation: Modulations supported by the product (required), multi-select: QPSK / 16QAM / 64QAM / 256QAM, QPSK + 16QAM selected by default.


  • CC on one port: Whether the two carriers are output from the same antenna port (required): Yes / No.


  • Num of Chains: Number of transmit chains (TX).


  • Antenna Gain: Antenna gain and cable loss configuration:

    • Title / Gain: Antenna number and gain (dBi) for each carrier band.

    • Cable Loss: Cable loss from the product's antenna port to the Switch Box or spectrum analyzer. How to Create Common Cable Loss.

    • Switch Box Port: Port number of the switch connected to the antenna.


  • Item List: Test items included in FCC LTE-CA. Items not applicable to CA (e.g., F402 / F403 / F405) are greyed out automatically:

    • (F400) Duty Cycle

    • (F401) Effective (Isotropic) Radiated Power Output Data

    • (F402) Frequency Stability (greyed out for CA)

    • (F403) Modulation Characteristics (greyed out for CA)

    • (F404) 99% & 26dB Bandwidth

    • (F405) Peak-Average Ratio (greyed out for CA)

    • (F406) Spurious Emission

    • (F407) Adjacent Channel Leakage Ratio

    • (F499) Form731 — FCC Form 731 report


  • UE Control: Whether the software automatically controls the sample, default OFF.


  • UE Connect: UE connection waiting time (seconds), default 60.


Advanced Setting

FCC_LTE-CA_advanced

All settings in Advanced Setting can generally be kept at their default values. Adjust them only when the test results are abnormal or there are special test requirements.


  • DC Factor: Whether to enable duty cycle factor correction. For spurious emission tests (TDD).


  • Switch Box: Whether to use a Switch Box (RF switch).


  • External Filter: Whether an external filter is used in the RF path.


  • Work Temp: Normal operating temperature range (°C).


  • Rated Voltage: Rated operating voltage (VAC / VDC).


  • Segment: Band segmentation mode: Single / Multi. For the F406 band edge test.


  • UL-DL Config: LTE TDD uplink-downlink subframe configuration (0 ~ 6). Only relevant for TDD.


  • CSE: Conducted Spurious Emissions setting. Below 30MHz additionally tests 9 kHz ~ 150 kHz / 150 kHz ~ 10 MHz / 10 MHz ~ 30 MHz.


  • Hide Image Elements: Elements to hide in report images (e.g., the Ant marker).


  • Duty Cycle Test Mode: Standard / OneBand.


  • Min Idle: Minimum idle time (ms) for the duty cycle test.


  • Check Margin: Test margin check. Select an Item and fill in Value(dB); results with a margin smaller than the set value will be flagged.


  • Special Setting: Special settings. Options prefixed with [D] are debug options:

    • [D] Virtual Data / [D] Ignore BaseStation / [D] Ignore Cell Connected / [D] Random Data / [D] Ignore Eut Confirm / [D] Random Status: Debug options.

    • Manual Network Signal: Set the Network Signal manually.

    • Hide SweepTime (CSE): Hide the CSE sweep time. Requires a recalculation to take effect (ReCalc).

    • Remove Raw Trace: For F406, remove the raw trace and hide RBW/VBW.

    • PCC:1RB0+SCC:1RBmax: If selected, the original PCC:1RB0+SCC:1RB0 or PCC:1RBmax+SCC:1RBmax RB allocations in all test items will be changed to PCC:1RB0+SCC:1RBmax.

    • Power Option 2: Use Option 2 for CBSD band power tests.

    • Mask for BRS/EBS: Emission mask replaces the band edge test for Band 7 / 38 / 41.

    • RBW 300Hz for B26/n26: Refer to KDB 971168 D02 Section VIII (c), Part 90 (814-824 MHz).

    • SIM Model Number: SIM card model, default P0250. For MT8000 / MT8821.

    • Input Level: Input level (dBm).
