It is designed to connect with a compatible computer via Universal Serial Bus interface. Connections of EUT (1)The power port is connected with the AC power source by a power adaptor. (2)The USB port of EUT is connected with the USB port of personal computer. (3)The LAN jack is connected with a RJ45 cable terminal Test method Pretest was found that the emission of operating mode is worse than standby mode. So, The final test is made at the operating mode. During testing, the EUT was operated at printing mode continuously. The test placement as the photographs showed is the worst case emission placed. (If the emission is close to the ambient, the resolution BW and view resolution will be reduced and the data will be recorded by detection of maximum hold peak mode.) The testing configuration of test setup is showing in the next page.
