Chapter 1: Operator Information

Application of the unit

The VOR/ILS Analyzer EVS200 is used for checking terrestrial radio navigation facilities at airports. Following components of ILS- and VOR-systems can be checked:

￿approach to land ILS (Instrument Landing System)

￿ direction localizer LLZ (Localizer)		108 to 118 MHz
￿	glideslope system GS (Glideslope)	320 to 340 MHz
￿	OM (Outer Marker)	75 MHz
￿	MM (Middle Marker)	75 MHz
￿	IM (Inner Marker)	75 MHz

￿short and medium range navigation

￿ VOR (VHF Omni Range) omnidirectional beacon 108 to 118 MHz

The following measurements can be carried out:

￿DDM (indication also in 1 / μA / %), SDM, modulation factor

￿absolute level

￿delta level (Δ level)

￿VOR parameter

￿ILS parameter

￿75-MHz beacon parameter

Ranges for measurements are e.g:

￿dynamic runway surveying (limited through high measurement speed (90 measurements/s))

￿static distant field surveying

￿function monitoring of transmitting field stations with data tele-transmitting

￿surveying of transmitting antenna characteristics through "Δlevel-mode"

￿Clearance & Glidepath (common parameter analysis without disconnecting the transmitting station)

￿measuring and evaluating of corresponding parameters at high interference intensity

Due to versatile power supply facilities the VOR/ILS Analyzer EVS200 is suitable for operation in field (battery supply), in vehicles (12-V board supply), and in the lab (AC supply). Among others it is pos- sible to remote control the unit via the RS-232-Interface and recalling all obtained data. Further more the corresponding parameters of the DSP can be taken at the multifunction output (DSP OUT) for further analysis (e.g. XY-tracer).
