Identification of Equipment Under Test (EUT) Description: FMCW Radar – Main Unit Brand Name: Blighter Model Name or Number: B422-NBSP Serial Number: 6B501 Hardware Version Number: BoM / Rev – Main 6BA39B/01 Software Version Number: Build 81 FCC ID Number: UFQB400SPNBMAIN 3.2. Description of EUT The equipment under test was the Main Unit of a multi-frequency ground surveillance radar system that can scan and detect moving vehicles and persons over a 180º area and can operate up to a range of 16 km. The main radar unit contains a GPS receiver and Wireless LAN transceiver (WLAN). The EUT assembly was mounted onto a tripod for test purposes. A personal computer (PC) is normally connected to the main radar unit by Ethernet or WLAN. The radar system can be configured and monitored from the PC. The Client stated that power to the EUT is provided from a DC supply only. The Client stated that an electronic test target was not required. 3.3. Modifications Incorporated in the EUT No modifications were applied to the EUT during testing.
