Product overview
The R&S®EVS300 is a portable level and AM analyzer for commissioning, checking and maintaining ILS (instrument landing system), VOR (VHF omnidirectional range) and marker beacon systems. An internal rechargeable battery and a rugged housing make it a natural tool for mobile measurements in the field with no mains supply, while its high measurement rate and trigger/synchronization functions also suit flight inspection systems. The R&S®EVS300 was the first ILS/VOR test receiver on the market to meet the requirements of ground measurement and flight inspection systems at once, so ground and airborne signal analysis correspond directly (as ICAO 8071 recommends). A built-in data logger provides ample storage for continuous recording of every signal parameter. Please note: this product is discontinued, and we recommend the successor model, the R&S®EVSG1000.
Key features
- Very high measurement rate: up to 100 measurements per second for flight inspection and runway measurement, fast enough to catch effects such as scalloping
- Precise real-time AM analysis: purely digital signal processing with a 16-bit analog-to-digital converter sampling at the IF, which removes the ripple and temperature drift that crystal filters introduce
- Built-in automatic calibration generator: very high level measurement accuracy with long-term stability, and a wide dynamic range from a switchable preamplifier and attenuator
- Simultaneous course and clearance signal analysis: the R&S®EVS-K3 option measures both carriers of a dual-frequency ILS system at once, including their level ratio and phase relationship
- Optional second signal processing channel (option R&S®EVS-B1): simultaneous localizer and glide path measurement, as flight inspection systems require
- Full trigger and synchronization: a trigger input plus synchronization over GPS (R&S®EVS-K2), RS-232 and Ethernet
- Large built-in data logger: stores every measurement parameter even at the highest rate, up to 1,000,000 records, with graphical display and USB export
- AF baseband input: analyse the ILS or VOR baseband signal directly, which makes faults easier to locate
- Integrated web server: read results and change settings remotely from a standard browser, with no dedicated software
- Rugged and portable: meets the MIL-STD-810D vibration and shock requirements, and a wide input voltage range (10 V to 28 V) suits vehicle and airborne use
Typical applications
- Commissioning, maintenance and periodic calibration checks of ILS ground systems (localizer LLZ, glide path GS, marker beacon MB)
- Measurement of VOR omnidirectional range stations and verification of bearing accuracy
- Integration into flight inspection systems: simultaneous localizer and glide path measurement as recommended by ICAO 8071
- Runway measurement: continuous graphical recording and analysis of DDM, SDM and level
- VHF data link testing for GBAS and SCAT ground-based augmentation systems
- DME pulse shape, timing and peak power measurement (option R&S®EVS-K6)
- RF spectrum analysis (70 MHz to 350 MHz) for spurious signals in the ILS/VOR and communications bands
