Creating a Test Plan - CE NR-BS ​

The CE NR-BS option is used for EU CE (RED) certification testing of 5G NR base station products. Base station testing feeds the test signal via a signal generator (VSG) and measures the output with a spectrum analyzer (SA).

Basic Settings ​

CE_NR-BS_overview

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

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

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

  • BS Type: Base station type (required): BS Type 1-C (conducted) / BS Type 1-H (hybrid).

  • Equipment Type: Base station class (required): Local Area BS / Medium Range BS / Wide Area BS.

  • SCS: Subcarrier spacings (kHz), multi-select: 15 / 30 / 60.

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

  • Band Info: NR bands supported by the product:

    • Band: NR band number, e.g., n1 / n78. The downlink frequency is filled in automatically.

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

    • Prated, c, AC(dBm): Rated output power per carrier per antenna connector.

    • Total Power(dBm): Total output power.

  • BW Comb: Bandwidth combination table. For each Index, configure Carrier Type / SCS / 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 CE NR-BS, all selected by default:

    • (C5BS00) Duty Cycle

    • (C5BS01) Base Station Maximum Output Power

    • (C5BS02) Operating Band Unwanted Emissions (OBUE)

    • (C5BS03) Adjacent Channel Leakage Power Ratio (ACLR)

    • (C5BS04) Transmitter Spurious Emissions

    • (C5BS05) Transmitter Intermodulation (EMask)

    • (C5BS06) Transmitter Intermodulation (ACLR)

    • (C5BS07) Transmitter Intermodulation (TxSe)

    • (C5BS08) Receiver Spurious Emissions

  • Test Mode: 3GPP NR test models, multi-select: NR-FR1-TM1.1 / TM3.2 / TM3.1 / TM3.1a / TM1.2 / TM3.3. 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 ​

CE_NR-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.

  • Blocking Step: Frequency step (MHz) for the Receiver Blocking test.

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

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

  • UE Control: How to control the sample restart:

    • OFF(Manual): Manual control, no software control.

    • ADB(USB): Control the sample via ADB.

    • DC Power: Restart the sample by switching the DC power supply.

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

  • Env: Environmental conditions, multi-select: NTNV / LTLV / LTHV / HTLV / HTHV.

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

  • 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 Duration: Set the Duration manually.

    • Manual Network Signal: Set the Network Signal manually.

    • Manual Output Level: Set the Output Level manually.

Corresponding software option: NR BS
