The R&S®EVS300 is a portable level and modulation analyzer designed especially for starting up, checking and maintaining ILS, VOR and marker beacon systems. The integrated rechargeable battery and robust design make it the ideal choice for mobile, mains-independent measurements in the field. Due to the high measurement speed and the trigger/synchronization functions, the R&S®EVS300 is also tailor-made for deployment with flight inspection systems. The R&S®EVS300 is the first test receiver for ILS/VOR signals that meets the demands of ground measurements and flight inspection systems. This permits the direct correlation of ground- and air-based signal analysis as recommended in ICAO 8071.

For the user, an extensive selection of software options simplifies regular measurement tasks. FFT, frequency scan and oscilloscope options make it possible to analyze signals in the frequency and time domain without carrying along extra test and measurement equipment. The integrated data logger provides enough memory to continuously record all signal parameters. The results can be graphically presented directly on the large color display of the R&S®EVS300. During flight inspection, the optional second signal processing channel of the R&S®EVS300 permits the simultaneous measurement of localizer and glideslope signals at continuously high rates. When equipped with the GPS option, the R&S®EVS300 also stores the (D)GPS position with each ILS/VOR/MB measurement at the time it was taken.
