Overview The VHF/UHF Digital Wideband ­Receiver R&S®EM 550 is ideally suited for military monitoring tasks and spectrum monitoring in line with ITU recommendations as well as for radio investigation services. The ¸EM 550 is prepared to meet any ­future demands in the field of receiver and analyzer technology for the purpose of frequency spectrum and signal analysis. The receiver is softwarecompatible with the ¸EB 200/ESMB family, thus providing an easy way to upgrade existing radiomonitoring systems. Description The ¸EM 550 covers the wide frequency range from 20 MHz to 3.6 GHz. High level mixers...

◆ Gain control (GC) Automatic (AGC) and manual (MGC) gain control; the MGC setting ­covers the input signal range from –30 dBµV to +130 dBµV ◆ Video panorama Spectrum of the demodulated signal with analysis features (squared AM, FM) ◆ IF panorama (option) Span range 10 kHz to 9.6 MHz ◆ ITU measurement (option) AM modulation index (AM+, AM–, AM) ◆ FM deviation (FM+, FM–,FM) ◆ PM deviation (0 π to 4 π) ◆ Bandwidth (0 MHz to 9.6 MHz) In the Memory Scan mode, the ­receiver settings can be programmed for the monitoring of up to 10000 channels. These channels can be scanned with the Memory Scan command....

Applications Due to its high scan speed, the receiver is ideally suited for fast and reliable detection of all types of signals in the wide field of civil and military monitoring, paramilitary monitoring, homeland security, secret services, signal investigation services, etc. No matter whether fixed frequency emissions, frequency-agile signals such as hoppers, pulsed periodic or non-periodic emissions are to be detected, nothing is lost in the scenario. This includes the following: ◆ Detection of signals in the RF spectrum ◆ Memory scan of up to 10000 ­memory channels ◆ Frequency scan in predefined...

Civil monitoring in line with ITU r ­ ecommendations Owing to its performance, the R&S®EM 550 fulfills all the requirements for measurements in line with ITU-R specifications (ITU Spectrum Monitoring Handbook, 2002). If the R&S®EM 510IM option is installed, the following measurements can be performed: ◆ Frequency and frequency offset in line with ITU-R SM377 ◆ Field strength in line with ITU-R SM378 ◆ Modulation in line with ITU-R SM328 ◆ Spectrum occupancy on control PC in line with ITU-R SM 182/SM 328 ◆ Bandwidth in line with ITU-R SM443 ◆ Detection of mono or stereo transmissions Radio data...

Designed to meet the standards The receiver has been designed for sta- tionary and mobile use in accordance with the recommendations for class C instruments. Careful shielding and fil- tering of all input and output lines en- sure ultralow spurious emissions and For applications in a vehicle the receiver can be operated via the DC input directly from the vehicle battery. Diagnostics included The receiver is permanently monitored by built-in test (BIT). If deviations from nominal values are detected, an error message is generated with a code indi- cating the type of fault. For detailed in- formation,...
