Eng. Gheorghe SAMOILESCU, “Mircea cel Bătrân” Naval Academy, samoilescugheorghe@yahoo.com Eng. Serghei RADU, Barklav Company, sergradu@yahoo.com Laura CIZER, “Mircea cel Bătrân” Naval Academy Abstract: This paper presents the results of research conducted on board a ship at a customer’s request. The devices used during the experimentation, the values obtained and the entailing conclusions will be presented. Measurements were taken over a period of one year. Keywords: modulator, power sensor, electric field 1. INTRODUCTION In order to achieve electromagnetic field measurements on board the ship points of radiation increased concentration were selected. Within each point, background measurements as well as measurements by help of different broadcasting stations located in various frequency ranges and operating modes were conducted. [1, 2, 3] The gauging instruments that were used to carry out field measurements are hereby presented. The following equipment was used for the taking measurements: R&S FSP13, Spectrum analyzer 9 kHz - 13 GHz, -140 - +30 dBm, RBW 10 Hz - 10 MHz, TFT color display; R&S FSP-B1, Rugged case with variable carrying handle for all FSP models; R&S FSP-B16, LAN interface 10/100 base T for FSP with Nr.1164.4391.XX; R&S FSP-B9, Tracking generator for FSP, 9 kHz - 3 GHz, I/Q; modulator; R&S FSP-B28, Trigger port for FSP; for indication of trigger conditions (necessary for operation with TS-EMF); R&S FSP- B30, DC power supply 12 - 28 V for FSP spectrum analyzer and ESPI test receiver; R&S FSP-B31 NiMH battery pack + charger for FSP, requires FSP-B1 and FSP-B30; R&S FS-K9 Measurements with NRP power sensors NRP-Z11 / Z21 / Z22 / Z23 / Z24 / Z51 / Z55 / Z91 requires NRP-Z3 or NRP-Z4 and specialized software. The measurement configuration is shown in Figure 1 below. Fig. 1. Measurement Components
