3.2 ISRT Tool Test Procedure

The ISRT tool is generally used for regulatory approval such as BT SIG/QDID, FCC ID, CE and so on. The following ISRT test procedures explain the common usage of the ISRT tool on a Windows® PC. For more details on the ISRT tool, refer to the ISRT User Manual in the ISRT tool release package,.

  1. Open the ISRT tool and click CREATE to select the test solution.

  4. For Continuous Waveform (CW) mode Tx power adjustment, follow the procedure below:
    1. In “MODE”, select TX.
    2. Select “TX Modulation”: OFF
    3. In “Channel”, select the right channel (ch0~ch78).
    4. Select “TX POWER TRIM Level” as PL0 or PL2.
    5. Click START to perform TX power test.
    6. Select Trim Power Up/ Trim Power Down to adjust the RF power to expected power level:
      • For PL0,+10dBm is the recommended target power level
      • For PL2, 0dBm is the recommended target power level
    7. Stop test then store the Tx parameters.
    8. Select Save To Device to store the trimmed RF power parameter to DUT.
    9. Select Save To File to store the trimmed RF power parameter to file as record.

    Note: Enable “Temperature Compensation” if temperature range other than room temperature is required.
  5. For TX modulation test, follow the procedure as below (non-signaling test):
    1. In “MODE”, select TX.
    2. Select “TX Modulation”: ON
    3. In “Channel”, select the right channel (CH0~CH78).
    4. Set “Packet Count” as Continue, “Packet Type” as default 3DH5 and “Payload Type” as PRBS.
    5. Click START to test with the RF tester.

    Note: Enable “Temperature Compensation” if temperature range other than room temperature is required.
  6. To enable Test mode for signaling test with RF tester (for example, MT8852B), follow the procedure as below:
    1. Select “TEST MODE”.
    2. Select “Temperature Compensation”.
    3. Click START to start auto test with tester.

  7. For BLE TX test, follow the procedure below:
    1. In “MODE”, select TX under the BLE tab.
    2. Select “Temperature Compensation”.
    3. Set “TX POWER TRIM” parameters (TX Modulation ON, Channel Number, Length and Payload Type).
    4. Click START to start TX test with tester.
    5. Select Power Up/Power Down to adjust the RF power to the expected power level.
    6. Stop test then store the TX parameters.
    7. Select Save To Device to store the trimmed RF power parameter to DUT.
    8. Select Save To File to store the trimmed RF power parameter to file as record.
