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 /
µ
A / %), SDM, modulation factor
absolute level
delta level (
∆
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 "
∆∆∆∆
level-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).
