3.4 Occupied Channel Bandwidth (OCBW) - EN 300 328

The measurements for Occupied Channel Bandwidth is performed at normal environmental conditions only. The test results comply with the limits shown in the Limits on Occupied Channel Bandwidth - Non-FHSS Equipment table of CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1] and are recorded in the test report. The test procedure for Occupied Channel Bandwidth measurement is described in the following steps:

  1. Connect the EUT as shown in Figure 2-1.
  2. Use Spectrum Analyzer as test equipment.
  3. For a detailed test procedure, see clause 5.4.7.2.1 of EN 300 328 [3].
  4. Switch ON the EUT and other test equipment.
  5. Set the Spectrum Analyzer to the following settings:
    1. Center Frequency: The center frequency of the channel under test
    2. Reference Level: 30dBm
    3. Frequency Span: > 2*Nominal Channel Bandwidth
    4. RBW: ~ 1% of the Frequency Span
    5. VBW: 3 * RBW
    6. Sweep Time: 1 Sec
    7. Detector: RMS
    8. Trace Mode: Max Hold
  6. Use the Radio Testing Tool [9] to setup and configure the EUT. For setting and up configuring the EUT, see the Radio Testing Tool User's Guide [10].
  7. Open the Radio Testing Tool [9] and setup the link with the EUT by using the Setup tab.
  8. Open the Tx tab and set the transmission mode to “Continuous”.
  9. Configure the EUT to the desired parameters such as Channel/Frequency, Data Rate, Data Pattern, Power Level, and so forth).
  10. Click on “ Start Tx Testing”
  11. Observe the Tx signal on the spectrum analyzer. When the trace is complete, find the peak power by using peak marker function.
  12. Measure OCBW by using the 99% bandwidth function of the spectrum analyzer and record it.
  13. Repeat the above for other data rates/modulations and also other desired channels.
  14. The Occupied Channel Bandwidth (OCBW) complies with the limits shown in the Limits on Occupied Channel Bandwidth - Non-FHSS Equipment table of CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1] for all the above test cases.
