CONDUCTED RF EMISSION TEST: The 50-ohm input of the Agilent E4402B spectrum analyser was AC-coupled to the 5V supply of the module. While the module was running the universal demo menu, the spectra shown overleaf were taken. Note that all peaks are harmonics of 92 MHz.   TU480 results Start Stop Significant UUT peaks  MHz 301 MHz -56dBm @275.5 MHz, 184 MHz 300 MHz 600 MHz -57dBm @460 MHz, 368 MHz, 552MHz TU480x272C-K612A1TU v12   TU640 results Start Stop Significant UUT peaks 1 MHz 301 MHz -60dBm @ 28 MHz 300 MHz 600 MHz -66dBm @ 419 MHz   TU800 results Start Stop Significant UUT peaks 1 MHz 301 MHz -45dBm @ 184 MHz, 276 MHz 300 MHz 600 MHz -66dBm @ 394 MHz
