1. The unit may be used only in the operating con-  
ditions and positions specified by the manufac-  
turer. Unless otherwise agreed, the following  
applies to R&S products:  
7. It is not permissible to interrupt the PE conduc-  
tor intentionally, neither in the incoming cable  
nor on the unit itself as this may cause the unit  
to become electrically hazardous.  
Pollution severity 2, overvoltage category 2, IP  
degree of protection 2X, altitude max. 2000 m.  
The unit may be operated only from supply net-  
works fused with max. 16 A.  
Any extension lines or multiple socket outlets  
used must be checked for compliance with rele-  
vant safety standards at regular intervals.  
8. If the unit has no power switch for disconnection  
from the AC supply, 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 suit-  
able for providing disconnection from the AC  
supply.  
2. For measurements in circuits with voltages Vrms  
> 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 con-  
nections are made (installation and cabling of  
the unit to be performed only by qualified techni-  
cal personnel).  
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.  
4. For permanently installed units without built-in  
fuses, circuit breakers or similar protective de-  
vices, the supply circuit must be fused such as  
to provide suitable protection for the users and  
equipment.  
Prior to performing any work on the unit or  
opening the unit, the latter must be discon-  
nected from the supply network.  
Any adjustments, replacements of parts, main-  
tenance 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, insulation-  
resistance, leakage-current measurement, func-  
tional test).  
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 different 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 con-  
nected.

Chapter 3: Operation  
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 in-  
stalled battery (option) will be charged.  
Details see item "Battery Operation"  
(page 12).  
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).  
ß
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").

Selftest (BITE)  
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 pos-  
sible 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".

VOR/ILS Analyzer EVS200  
Operation of the unit  
Chapter 3: Operation  
Because of the many universal measuring functions of the VOR/ILS Analyzer EVS200 the operation  
has to be carried out according to the following instructions. Basically all measurement parameter set-  
tings are realized through softkeys and the mode keys. An activated mode is shown by a luminous  
LED (beside the belonging mode key). All important signal parameters are analyzed by the DSP (digital  
signal processor) and indicated on the display. Due to the variety of the analyzed parameters the indi-  
cation in the ILS and VOR mode is subdivided into two display parts ("DISPL 1/2" and  
DISPL 2/2").  
The RS-232-Interface operation of the VOR/ILS Analyzer EVS200 is  
described in section "Operating the VOR/ILS ANALYZER EVS200  
via RS-232-Interface"

Chapter 3: Operation  
RS-232-Interface operation  
All important unit functions can be remote controlled via the RS-232-Interface (V24 standard) by a PC  
terminal which can be operated with commercial terminal programs (e.g. Telix, Procomm...). AS a data  
terminal (DDE) the VOR/ILS Analyzer EVS200 must be connected with a RS-232-1:1-Interface. Also  
it is possible to control the unit with an user defined program. The necessary commands for that pur-  
pose are described below.  
COM-Parameter  
The com parameters parity, number of data bits, and stop bits cannot be changed and are defined as  
"firmware“.  
non parity bit  
8 data bits  
1 stop bit  
(N),  
(8),  
(1).  
Handshake  
Hardware handshake is renounced.  
Handshake is performed by software as a transmitted sequence e.g. "READY“ or as a measuring  
value or a tuning value e.g. "RF107000“.  
Control commands  
There are two categories of control commands.  
super commands (mode independant, unit related)  
mode dependant commands (specified mode must first be selected)  
The following table makes clear the control commands structure.

FA1  
<Fast DDM measuring on>  
Activating the Fast DDM measurement  
The command FA1 switches on the fast DDM measurement. The measuring, used only for landing  
path measurement can only be activated through a controller. The output is performed as DDM value  
with RF level (see example) and can be processed accordingly with calculation programs e.g. like  
Excel etc. A capacaty of 34 measurements /s at a baud rate set to 19200 baud will be reached. This  
conforms to a time interval of 30 ms. The measurement values (DDM, RF level) can be read in and  
output as a text file corresponding to the terminal program.  
To reach 34 meas/s the baud rate must be set to 19200 baud in the Setup of the  
VOR/ILS Analyzer EVS200. It must be attended the acceptance of the data transfering  
rate by the terminal program.  
The measurement can be stopped through the command FA0 (refer to Command  
FA0).  
Example:

FA2  
<Fast DDM measuring on>  
Activating the Fast DDM measurement  
The command FA2 switches on the fast DDM measurement. The measuring, used only for landing  
path measurement can only be activated through a controller.  
The command FA2 performs the continuous measurement and output of the DDM, RF level, Mod-  
factor 90 Hz and Modfactor 150 Hz with a transmission speed of about 20 measurement value sets  
(DDM, RF level, AM90, AM150) per second. This conforms to a time interval of 50 ms. The stated  
RS-232-transmission times are related to 19.200 Baud.  
The measurement values can be read in and output as a text file corresponding to the terminal pro-  
gram.  
To reach 20 meas/s the baud rate must be set to 19200 baud in the Setup of the  
VOR/ILS Analyzer EVS200. It must be attended the acceptance of the data transfering  
rate by the terminal program.  
The measurement can be stopped through the command FA0 (refer to Command  
FA0).

FA3  
<Fast DDM measuring on>  
Activating the Fast DDM measurement  
The command FA3 switches on the fast DDM measurement. The measuring, used only for landing  
path measurement can only be activated through a controller. The command FA3 performs the con-  
tinuous measurement and output of the DDM, RF level, Modfactor 90 Hz and Modfactor 150 Hz.  
The 50-ms measurement interval consists of DSP analysis, DSP data transmission to the host  
processor and conversion of the DSP raw measurement value into DDM, dBm and AM %. The  
measurement values output is performed in this mode as interrupt operation via RS232 interface.  
In this Fast-Mode (FA3) a measurement value set will only be transmitted to the PC if it is demanded  
by a short command (1 ASCII-Character). The response from the EVS200 is performed without a  
longer delay within about 15 to 20 ms between measurement value demand and measurement  
value transmission. The stated RS-232-transmission times are related to 19.200 Baud.  
The measurement values can be read in and output as a text file corresponding to the terminal pro-  
gram.  
The baud rate must be set to 19200 baud in the Setup of the VOR/ILS Analyzer  
EVS200. It must be attended the acceptance of the data transfering rate by the  
terminal program.  
The measurement can be stopped through the command FA0 (refer to Command
