24、radation due to the presence of an unwanted input signal (blocking signal) on frequencies other than those of the operating bands provided in ETSI EN 301 893 1, clause 1. 4.1.2 Performance Criteria The minimum performance criterion shall be a PER of less than or equal to 10 %. The manufacturer may d
25、eclare alternative performance criteria as long as that is appropriate for the intended use of the equipment. See clause 4.2.1. 4.1.3 Limits While maintaining the minimum performance criteria as defined in clause 4.1.2, the blocking levels at specified frequency offsets shall be equal to or greater
26、than the limits defined in table 1. Table 1: Receiver Blocking parameters Wanted signal mean power from companion device (dBm) Blocking signal frequency (MHz) Blocking signal power (dBm) (see note 2) Type of blocking signal Master or Slave with radar detection (as defined in ETSI EN 301 893 1, table

28、iteria as defined clause 4.1.2 in the absence of any blocking signal. NOTE 2: The levels specified are levels in front of the UUT antenna. In case of conducted measurements, the same levels should be used at the antenna connector irrespective of antenna gain. 4.2 Receiver Blocking Test Method 4.2.1
29、Test conditions The UUT shall operate in its normal operational mode. This test shall be performed on one operating channel within each of the sub-bands defined in ETSI EN 301 893 1. Devices which can change their operating frequency automatically (adaptive channel allocation), this function shall b
30、e disabled. If the equipment can be configured to operate with different Nominal Channel Bandwidths (e.g. 20 MHz and 40 MHz) and different data rates, then the combination of the smallest channel bandwidth and the lowest data rate for this channel bandwidth, which still allows the equipment to opera
31、te as intended, shall be used. This mode of operation shall be aligned with the performance criteria defined in clause 4.1.2 as declared by the manufacturer and shall be described in the test report. It shall be verified that this performance criteria as defined by the manufacturer is achieved durin

All other receiver inputs shall be terminated. Figure 1 shows the test set-up which can be used for performing the
33、 receiver blocking test. The companion device may require appropriate shielding or may need to be put in a shielded room to prevent it may have a negative impact on the measurement. Figure 1: Test Set-up for receiver blocking Step 1 to step 6 below define the procedure to verify the receiver blockin
34、g requirement as described in clause 4.1. Step 1: The UUT shall be set to the first operating frequency to be tested. Step 2: The blocking signal generator is set to the first frequency as defined in table 1. Step 3: With the blocking signal generator switched off a communication link is set up betw
35、een the UUT and the associated companion device using the test setup shown in figure 1. The attenuation of the variable attenuator shall be increased in 1 dB steps to a value at which the minimum performance criteria as specified in clause 4.1.2 is still met. The resulting level for the wanted signa
36、l at the input of the UUT is Pmin. This signal level (Pmin) is increased by 6 dB resulting in a new level (Pmin+ 6 dB) of the wanted signal at the UUT receiver input. Step 4: The level of the blocking signal at the UUT input is set to the level provided in table 1. It shall be verified and recorded
37、in the test report that the performance criteria as specified in clause 4.1.2 are met. If the performance criteria as specified in clause 4.1.2 are met, the level of the blocking signal at the UUT may be further increased (e.g. in steps of 1 dB) until the level whereby the performance criteria as sp
38、ecified in clause 4.1.2 are no longer met. The highest level at which the performance criteria are met is recorded in the test report. Direct.

Step 6: Repeat step 2 to step 5 with the UUT operating at the other operating frequencies at which t
40、he blocking test has to be performed. 4.2.2.2 Radiated measurements When performing radiated measurements on equipment with dedicated antennas, measurements shall be repeated for each alternative dedicated antenna. A test site as described in ETSI EN 301 893 1, annex B and the measurement procedures
41、 as described in ETSI EN 301 893 1, clause C.2 or clause C.3, shall be used. The test procedure is further as described under clause 4.2.2.1. The level of the blocking signal at the UUT referred to in clause 4.2.2.1, step 4 is assumed to be the level in front of the UUT antenna(s). The UUT shall be
42、positioned with its main beam pointing towards the antenna radiating the blocking signal.
