ILS signal analysis

• ·        Highly accurate localizer, glidepath and marker beacon measurements
• ·        Parallel localizer and glidepath measurements (second independent signal processing unit, option R&S EVS-B1)
• ·        Simultaneous dual-channel course/clearance measurements (option R&S EVS-K3)
• ·        Realtime distortion measurement of ILS modulation signals (R&S EVS-K2, -K3, THD)

VOR signal analysis

• ·        Precise checking of CVOR/DVOR antenna systems in the field
• ·        Selective measurement of modulation depth and deviation as well as display of useful and interfering signals

Further special characteristics

• ·        Steep-edge preselector filters for high immunity to interference
• ·        Frequency scan (option R&S EVS-K1) with a dynamic range of up to 100 dB
• ·        Operating time of 8 h to 10 h on battery power during continuous measurement
• ·        FFT analysis of AM signals (option R&S EVS-K4)
• ·        Enhanced realtime data logging with graphical result display
• ·        Rugged and compact design for use in the field
• ·        Embedded web server for remote access
