5.5.4.2.1 Conducted measurement
In case device is using multiple receive chains only one chain needs to be tested. All other receiver inputs shall be terminated. Figure 6 shows the test set-up which can be used for performing the test. The companion device and EUT may require appropriate shielding or may need to be put in a shielded room to prevent i...
