Creating a Test Plan - FCC LTE-BS ​

The FCC LTE-BS option is used for FCC / IC (ISED) certification testing of LTE base station products. Base station testing feeds the test signal via a signal generator (VSG) and measures the output with a spectrum analyzer (SA); no UE control is involved.

Basic Settings ​

FCC_LTE-BS_overview

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

  • IC: Whether to test according to Canadian IC (ISED) requirements as well, default No.

  • CC Num: Number of carriers. Note: changing CC Num will clear the Band Info.

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

  • Equipment Type: Base station class (required): Outdoor BS / Indoor BS / Other BS.

  • Carrier Type: Carrier types, multi-select: Single / Continuous / Non-Continuous.

  • Band Info: LTE bands supported by the product:

    • Band: LTE band number, e.g., Band 2 / 5 / 41. The downlink frequency is filled in automatically.

    • DL Frequency(MHz): Downlink frequency range, auto-filled and editable.

    • Rated Power Level(dBm): Rated power level.

    • Total Power(dBm): Total output power.

  • EUT Type: Type of the equipment under test (required): EUD / Class A CBSD / Class B CBSD. CBSD applies to the CBRS band (e.g., Band 48).

  • BW Comb: Bandwidth combination table. For each Index, configure Carrier Type / Bandwidth DL and the bandwidth of each carrier (CC1...); use the +/- icons to add or remove combinations.

  • Antenna Gain: Antenna gain and cable loss configuration:

    • Title / Gain: Antenna number and gain (dBi).

    • Cable Loss - VSG to EUT: Cable loss from the signal generator to the EUT.

    • Cable Loss - EUT to SA: Cable loss from the EUT to the 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-BS, all selected by default:

    • (F4BS00) Duty Cycle

    • (F4BS01) Effective (Isotropic) Radiated Power Output Data

    • (F4BS02) Frequency Stability

    • (F4BS04) 99% & 26dB Bandwidth

    • (F4BS05) Peak-Average Ratio

    • (F4BS06) Spurious Emission

    • (F4BS99) Form731 — FCC Form 731 report

  • Test Mode: 3GPP E-UTRA test models, multi-select: E-TM1.1 / E-TM3.2 / E-TM3.1 / E-TM3.1a. Select according to certification requirements.

  • Test Option: Test scope: Standard / All CC Combs (test all carrier combinations) / Only One Ant Port.

  • Continuous Type: Continuous carrier type: Standard / Non-Standard.

Advanced Setting ​

FCC_LTE-BS_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.

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

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

  • TX Power Arg: TX power evaluation method: AVG / MAX / MIN.

  • Work Temp: Normal operating temperature range (°C). Affects the frequency stability test.

  • Rated Voltage: Rated operating voltage (VAC / VDC). Affects the frequency stability test.

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

  • Duty Cycle Test Mode: Standard / OneBand. OneBand: a mode only measures one duty cycle.

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

  • 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.

    • Single Sweep (CSE): CSE uses single sweep. Requires a retest to take effect (ReTest).

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