Creating a Test Plan (Plan) ​

The TST PASS system uses a wizard approach to assist test engineers in creating reasonable test plans. Therefore, before creating a test plan, test engineers need to understand the product characteristics mentioned in the relevant standards and map these characteristics to the product functions. This way, a test plan that meets the standard requirements can be quickly created.

Common product characteristics are as follows:

Product Category

Un-licensed Products

  • Type: Technical Category, e.g., WiFi, Bluetooth, BLE, Zigbee, Proprietary (custom product)
  • Num of Chains: Number of transmit chains (antennas) the product has.

The following description about Beamforming is mainly aimed at the relevant regulations of the European Union CE.

  • Beamforming:

    For multi-antenna products, it is also necessary to consider whether the product supports Beamforming.

    • Beamforming Gain: For products that support beamforming, it is necessary to fill in the additional gain generated by the beamforming technology.

The following description about Correlation and Directional Gain is mainly aimed at the relevant regulations of North America FCC/IC.

  • Correlation:

    Correlation of multiple antennas. Generally, there are three options:

    Uncorrelated / CDD / Beamforming

    • Directional Gain: Directional gain declared by the customer (optional, default is 0, indicating no entry), abbreviated as DG in this manual. KDB 662911 provides the theoretical calculation formulas for Directional Gain under various correlation modes. If no value is entered here, the software will by default calculate the Directional Gain according to the methods given in KDB. Generally speaking, the DG calculated according to the formulas in KDB will be higher than the actual DG of the product, thus leading to a greater power back-off. This is unacceptable for manufacturers of some special products (such as professional routers), who may actually measure the DG themselves and provide the final measured DG to the laboratory. In this case, the DG declared by the manufacturer needs to be filled in here. If a value is entered here (not equal to 0), the software will use this value as the DG for subsequent calculations and will no longer calculate the DG based on the formulas in KDB.

  • Band:

    Operating frequency bands supported by the product.

    (Common in 5G WiFi products or other custom 5G products)

    • Cross Band CH: Confirm whether the product supports channels CH144, CH142, CH138 (5720, 5710, 5690).

  • Mode:

    Modes supported by the product,

    e.g., 802.11b/g/n/ax... for WiFi, or GFSK, 8DPSK, etc. for Bluetooth.

    • RU Config: RU configuration supported by 802.11ax devices.
  • Carrier Wave: Whether the product supports carrier wave transmission (commonly found in standards that require frequency error testing, such as MIC, SRRC, etc.).
  • TPC Support: Whether the product supports TPC function (applicable to 5G WiFi products or other custom 5G products using the 5250 ~ 5350 and/or 5470 ~ 5725 frequency bands).
  • DFS Type: DFS type of the product, e.g., Master - active listening device, Slave without Radar Detection - slave device without radar detection, etc.
  • Antenna Gain:
    • Title: Antenna number, named sequentially by default as 1, 2, 3, 4..., or manually input other names according to customer requirements.
    • Gain: Gain of each antenna in the corresponding frequency band.
    • Cable Loss: Cable loss of the RF cable from the product's antenna port to the Switch Box (RF port of the switch) or SA (Spectrum Analyzer, if not using a switch directly). How to Create Common Cable Loss.
    • Port: Port number of the switch connected to the product's antenna, e.g., Ant1 connected to port 1, Ant2 connected to port 2.
  • ENV: Required environmental conditions for testing. e.g., NTNV, LTNV, HTNV (Normal Temperature Normal Voltage, Low Temperature Normal Voltage, High Temperature Normal Voltage).

Product Category

Licensed Products

  • Type: Technical Category, e.g., Sub 6G SA / NSA, GSM / WCDMA / LTE.
  • Num of Chains: Number of transmit chains (antennas) the product has.
  • SCS: Subcarrier Spacing, applicable to 5G NR.
  • Band: Operating frequency bands supported by the product, e.g., Band 1/2/3/4, n41/n78/n79, etc.
  • Antenna Gain:
    • Title: Antenna number, named sequentially by default as 1, 2, 3, 4..., or manually input other names according to customer requirements.
    • Gain: Gain of each antenna in the corresponding frequency band.
    • Cable Loss: Cable loss of the RF cable from the product's antenna port to the Switch Box (RF port of the switch) or SA (Spectrum Analyzer, if not using a switch directly). How to Create Common Cable Loss.
    • Port: Port number of the switch connected to the product's antenna, e.g., Ant1 connected to port 1, Ant2 connected to port 2.
  • Release: 3GPP standard version referenced by the product design, e.g., Rel-15 / -16 / -17.
  • Blocking Step: Frequency step for out-of-band blocking test in Receiver Blocking, the default is 1MHz (WCDMA / LTE / 5G NR) or 200kHz (GSM) as required by the standard.

  • UE Control:

    Select the method to control the sample's restart or flight mode.

    • OFF (Manual): Manually control the sample's restart or flight mode, without using software control.
    • ADB (USB): Use ADB method to control the sample's flight mode.
    • DC Power: Allow the software to control the on/off of the DC Power to achieve sample restart.
  • Parameter Recall: Whether it is necessary to recall the parameter configuration file stored in the base station. If recall is needed, please fill in the path and name of the configuration file.
  • ENV: Required environmental conditions for testing. e.g., NTNV, LTLV, HTHV (Normal Temperature Normal Voltage, Low Temperature Low Voltage, High Temperature High Voltage).
