4.10 Receiver Blocking - EN 301 893

The measurements for Receiver Blocking are performed at normal environmental conditions only. The EUT is configured to operate in a normal operational mode and are tested on those channels and channel bandwidths specified in the Limits on Nominal and Occupied Channel Bandwidth table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1].

Figure 4-1 shows the test setup for the Receiver Blocking. The test results comply with the Limits on Receiver Blocking table 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 Receiver Blocking measurements is described in the following steps:

GUID-20200821-CA0I-WLBM-BKTN-79GSHTXDRDH7-low.gif Figure 4-1 Test Setup for Receiver Blocking – EN 301 893
  1. Make the test setup as shown in Figure 4-1.
  2. Switch ON the EUT and other test equipment.
  3. For test procedure, see clause 5.4.10.2.1 of EN 301 893 [4].
  4. Turn-Off the RF on the Blocking Signal Generator.
  5. Use the Radio Testing Tool [9] to setup and configure the EUT and the Companion device. For setting and up and configuring the EUT, see the Radio Testing Tool User's Guide [10].
  6. Open the Radio Testing Tool [9] and setup the link with the EUT by using the Setup tab.
  7. Open the Rx tab and select the desired parameters such as Channel/Frequency, Data Rate, Data Pattern, and so forth).
  8. Click on “Start Rx Testing”.
  9. Open the Radio Testing Tool [9] and setup the link with the Companion device by using the Setup tab or use the AP configuration tool to configure AP to the desired parameters (if AP is used as companion device).
  10. .Open the Tx tab, select the transmission mode to “packetized”.
  11. Configure the Companion Device to the same parameters such as Channel/Frequency, Data Rate, Data Pattern, Power and so forth) used for EUT.
  12. Click on “Start Tx Testing”.
  13. Adjust the Attenuator setting and or Tx power of the Companion device to obtain a desired signal level at the EUT port.
  14. Observe the Rx statistics on the Rx tab of the EUT. Make sure that the PER/FER is at 0% (no errors before adding the interferer).
  15. Observe the PER on the Rx statistics on the Rx tab of the EUT and adjust the desired signal level to a minimum by using an Attenuator and or Tx power of the Companion device to get the PER < =10% (minimum performance criteria).
  16. Note down the desired signal level as Pmin and increase the level of the desired signal to Pmin+6dB by using an Attenuator and or Tx power of the Companion device .
  17. Turn ON the RF signal on the Blocking Signal Generator, set the mode to CW, set the Frequecy as per the Limits on Receiver Blocking table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1] and adjust the level to the levels mentioned under the column “Slave without Radar Detection” in the Limits on Receiver Blocking table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1].
  18. Observe the Rx statistics on the Rx of the EUT. Measure the PER/FER and record it.
  19. If the PER /FER is <= 10%, then it passed the test at that blocking frequency.
  20. Repeat the above steps for other Blocking frequencies as per the Limits on Receiver Blocking table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1].
  21. Repeat the above for other data rates/modulations and also other desired channels.
  22. The Receiver Blocking test results comply with the limits shown in shown in the Limits on Receiver Blocking table in CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands [1] for all the test cases.
