Safety Instructions
This unit has been designed and tested in accordance with the EC Certificate of Conformity and has left the
manufacturer’s plant in a condition fully complying with safety standards.
To maintain this condition and to ensure safe operation, the user must observe all instructions and warnings
given in this operating manual.

1. The unit may be used only i n the operating conditions and positions specified by the manufacturer. Unless otherwise agreed, the following
applies to R&S products:
Pollution severity 2, overvoltage category 2, IP
degree of protection 2X, altitude max. 2000 m.
The unit may be operated only from supply networks fused with max. 16 A.
2. For measurements in circuits with voltages V
> 30 V, suitable measures should be taken to
avoid any hazards.
(using, for example, appropriate measuring
equipment, fusing, current limiting, electrical
separation, insulation).
3. If the unit is to be permanently wired, the PE
terminal of the unit must first be connected to
the PE conductor on site before any other connections are made (installation and cabling of
the unit to be performed only by qualified technical personnel).
4. For permanently installed units without built-in
fuses, circuit breakers or similar protective devices, the supply circuit must be fused such as
to provide suitable protection for the users and
equipment.
5. Prior to switching on the unit, it must be ensured
that the nominal voltage set on the unit matches
the nominal voltage of the AC supply network.
If a diff erent voltage is to be set, the power fuse
of the unit may have to be changed accordingly.
6. Units of protection class I with disconnectible
AC supply cable and appliance connector may
be operated only from a power socket with
earthing contact and with the PE conductor connected.

7. It is not permissible to interrupt the PE conductor intentionally, neither in the incoming c able
nor on the unit itself as this may cause the unit
to become electrically hazardous.
Any extension lines or multiple socket outlets
used must be checked for compliance with relevant safety standards at regular intervals.
8. If the unit has no power switch for disconnection
rms
from the AC s upply, the plug of the connecting
cable is regarded as the disconnecting device.
In such cases it must be ensured that the power
plug is easily reachable and accessible at all
times (length of connecting cable approx. 2 m).
Functional or electronic switches are not suitable for providing disconnection from the AC
supply.
If units without power switches are integrated in
racks or systems, a disconnecting device must
be provided at system level.
9. Applicable local or national safety regulations
and rules for the prevention of accidents must
be observed in all work performed.
Prior to performing any work on the unit or
opening the unit, the latter must be disconnected from the supply network.
Any adjustments, replacements of parts, maintenance or repair may be carried out only by
authorized R&S technical personnel.
Only original parts may be used for replacing
parts relevant to safety (eg power switches,
power transformers, fuses). A safety test must
be performed after each replacement of parts
relevant to safety.
(visual inspection, PE conductor test, insulationresistance, leakage-current measurement, functional test).

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 (∆ 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 possible 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).

Chapter 2: Preparation for Operation
Preparation for operation
Placing the unit
The VOR/ILS Analyzer EVS200 can be operated in any position without reduction in its function. Even
shocks during normal transportation or on mobile operation don’t reduce its function.
The unit works at ambient temperatures of -5 to +40°C.
Mains operation
Safety Rules
The VOR/ILS Analyzer EVS200 meets the safety rules in ag-
reement with VDE 0411 and VDE 0804 of safety class I. In
agreement with safety class I all mains circuitry must be insulated and the requirement is a good conductive and durable
together and ground wire connection of all touchable, conductive parts of the unit which can directly be alive in case of a
failure.
Mains connector (earthed plug) put only into a protective
contact socket. If there is a connector it must durable be
connected with a ground wire. The ground wire must not
be insulated.
Mains connection
Connect the VOR/ILS Analyzer EVS200 with the supplied power cord to the AC supply
(87 to 265 VAC / 47 to 63 Hz or corresponding to the technical data).
If the unit shall be connected to another AC supply the
corresponding safety rules must be observed!

Operation
Switch On/switch Off the unit at mains supply
With the mains switch at the rearside
switch the unit on or off.
With the switch "POWER" at the front
side switch the unit on or "STANDBY".
On switch position "STANDBY" the installed battery (option) will be charged.
Details see item "Battery Operation"
(page 12).
Chapter 3: Operation
Switch On/switch Off the unit at VDC supply
When the unit is supplied from the installed battery (option) or through the external DC input it must
be switched on or to "STANDBY" only with the Switch "POWER" at the frontside.
On external DC supply of the unit the installed battery
(option) will not be charged!
Switch on procedure
During the switch on procedure the VOR/ILS
Analyzer EVS200 performs a selftest (BITE). The
tested functions are indicated with "OK". This test
takes approx. 5 s. After that automatically it is
switched over to the startup mode which was set
in the setup.
Because of the displayed battery voltage
(U BATT) it is possible to value the charging
state of the installed battery (option).
ßßßß
Malfunctions of the BITE will be indicated by
"FAIL". In that case the unit does not switch over
to the startup mode (see also item "Selftest").
0796.1800.02 E-8 11
VOR/ILS Analyzer EVS200
Selftest (BITE)
Chapter 3: Operation
The selftest checks:
all operating voltages,
host processor,
memory,
DSP processor.
In case of an error the determined functional unit will be indicated with a "FAIL". If the internal
operating voltages totally fail or if they deviate extraordinary from the tolerances a selftest cannot
be carried out.
Error:
In case of an error the unit generally should be
switched off and after a few seconds it schould be
switched on again. If the error message is displayed
again it is recommended to send the unit to the
service, corresponding to Chapter 5 (Service).
Battery operation
The battery operation of the VOR/ILS Analyzer EVS200 is an optional component. It is always possible to retrofit the unit with this mode.
The unit automatically goes into battery operation when the external power supply (DC/AC) is switched
or cut off. The battery operation is indicated on the display by the battery symbol (
) in each mode.
The operation time is >100 minutes (max. brightness) or >150 minutes (at average brightness)
with a completely charged battery.
The charging state can be seen from the battery symbol on the display:
100% battery power
approx. 75 to 25% battery power
flashing symbol, approx. only 5 minutes operation is
ensured. Battery must be charged.
The battery will be charged on AC operation (as well during operation as on "STANDBY") and should
take at least 12 hours (charging time).
After 4 to 5 years or when defect the battery must be
changed according to Chapter 5 "Service".
