4.6 Power Spectral Density - EN 301 893

The measurements for Power Spectral Density are performed at normal environmental conditions only. The EUT is configured to the highest sated transmit output power level and tested on those channels and channel bandwidths specified in the Limits on Nominal and Occupied Channel Bandwidth table of CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1]. The test results comply with the limits shown in the Limits on RF Output Power and Power Density at the Highest Power Level (PH) in 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 Power Spectral Density 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 detailed test procedure for detailed test procedure, see clause 5.4.4.2.1.3 of EN 301 893 [4].
  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. RBW: 1 MHz
    4. VBW: 3 MHz
    5. Frequency Span: > 2*Nominal Bandwidth (for example, 40 MHz for a 20 MHz channel)
    6. Sweep Time: Auto
    7. Detector: Peak
    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. Record the frequency of the peak marker.
  12. Modify the settings of the Spectrum Analyzer to the following settings:
    1. Center Frequency: Equal to the center frequency of the marker (from the above step)
    2. Frequency Span: 3 MHz
    3. Reference Level: 30dBm
    4. RBW: 1 MHz
    5. VBW: 3 MHz
    6. Sweep Time: 1 Minute
    7. Detector: RMS
    8. Trace Mode: Max Hold
  13. Observe the Tx signal on the spectrum analyzer. When the trace is complete, find the peak power by using peak marker function. Record the highest power value (D in dBm / MHz).
  14. Add the antenna gain (G in dBi) and an additional beamforming gain (Y in dB, if applicable).
  15. The resultant Power Spectral Density (PSD) in e.i.r.p. equal to (D+G+Y) from the above steps. Record this value.
  16. Repeat the above for other data rates/modulations and also other desired channels.
  17. The Power Spectral Density (PSD) in e.i.r.p. complies with the limits shown in the limits shown in the Limits on RF Output Power and Power Density at the Highest Power Level (PH) table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands for all the above test cases.
