It has following features: 1. Connect up to 127 USB devices simultaneously. 2. Hot plug-n-play of USB devices. 3. Transmission bandwidth from 1.5 Mbps to 2.0 Mbps. 4. 1 USB upstream port with 4 USB downstream ports. 5. Self-powered or Bus-powered operation. 6. Over-current protection. 7. Fulfils USB –IF specification Reversion 1.1 8. Stand-alone or clips on 1999/2000 Philips CRT monitor base(s). Connections of EUT: (1) The power jack of the EUT is connected with the AC power source via a power adapter. (2) Connect the upstream port of EUT to USB # 1port of PC via A-to-B cable. (3) Plug one USB mouse into downstream #1port of EUT. (4) The other downstream ports are plugged in three USB cables terminal with 100Ω. 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 “transmitting” and “receiving” mode simultaneously. 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.
