Measurements were taken from 30MHz to 1Gz, then from 1GHz to 10GHz. All data presented is the measured results with any applicable correction factors applied via the test software. The 3 orthogonal axes of the WS900TX were examined in order to maximize the emissions. 2.0 Description 2.1 Equipment under test The WS900 consists of the wetness sensor/transmitter module and remote receiver unit. The transmitter emits a signal only when the sensor detects moisture. The receiver picks up the signal and an alarm tone is activated. The tone stops when the transmitter stops transmitting. On the unit tested, there was no provision for non-battery powered operation. 2.1.1 Identification: WS900Tx wetness sensor WS900Rx wetness receiver 2.1.2 EUT received date: 14 February 2002 2.1.3 EUT tested dates: 1 st , 4 th , 7 th , and 8 th March 2002 2.1.4 Manufacturer: Excel Engineering, HK 2.1.5 Serial number: WS900Tx wetness sensor, SN: 78 WS900Rx wetness receiver, SN: 12 NCEE R021802-01B FCC ID:OWGWS900Tx/Rx Page 4 of 19 2.2 Laboratory description All testing was performed at the NCEE Lincoln facility, which is a FCC registered lab. This site has been fully described in a report submitted to the FCC, and accepted in a letter dated May 4, 2001. Laboratory environmental conditions varied slightly throughout the tests: Relative humidity of 46 ± 5% Temperature of 21 ± 3° Celsius 2.3 Special equipment or setup The EUT was tested using new AAA batteries. A modified test probe was used so that the WS900Tx would continuously transmit. An actual probe was examined and no differences in the emission spectrum or emissions in excess of the limits were found to be coming from the EUT. 3.0 Test equipment used Serial # Manufacturer Model Description Last cal. 1647 EMCO 3142B Biconilog antenna 25-May-01 6415 EMCO 3115 DRG Horn 31-May-01 100037 Rohde & Schwarz ESIB26 EMI Test Receiver 11-Jun-01 082001/003 Rohde & Schwarz TS-PR18 Preamplifier 10-Aug-01 2575 Rohde & Schwarz ES-K1 Software v1.60 N/A NCEE R021802-01B FCC ID:OWGWS900Tx/Rx Page 5 of 19 4.0 Detailed Results 4.1 FCC Part 15.109 Radiated Emissions for Class ‘B’ devices, Rx The WS900Rx portion was tested in its standard configuration, with new batteries. Figures 1 and 2, in Appendix A, show the test setup used. The EUT was rotated and the mast was raised from 1 meter to 4 meters to find the highest emissions. No emissions were found to be in excess of the limits for Class ’B’ devices found in CFR 47, Part 15.109. The results can be seen in figures 5 and 6 in Appendix B. The highest peak values, below 1GHz, and the highest average values, above 1GHz, are shown below. The antenna on the receiver is attached via a screw that is enclosed within the case of the EUT. 4.2 FCC Part 15.203, Tx The WS900Tx antenna is copper rod that is soldered to the circuit board of the EUT and is completely enclosed within the unit. 4.3 FCC Part 15.249 Radiated Emissions, Tx The WS900Tx was tested for compliance to the limits in CFR 47, Part 15.249. Figures 3 and 4 show the setup used. Figures 7 through 10 show the plots of the results. The first 5 harmonics and the fundamental measurement are shown in the first table below, the remaining harmonics were indistinguishable from the noise floor. The second table contains the highest emissions while the EUT was not transmitting. No emissions beyond the carrier frequency exceed the general radiated emissions limit as set forth in 15.209.
