2. Introduction 


The range of FM NAVIGATOR 10, NAVIGATOR 100, NAVGATOR 1000 receivers 


The equipment that you have just acquired is a precision unit intended for physical and logical field analysis 
of FM multiplex composite signal components and the RF level of any FM radio station. 
The AZ10 and AZ100 versions are portable, the AZ1000 model is rack mount. This analysis can be carried 
out with ease due to an ergonomic man machine interface. 

. AZ10: FM Navigator. 

. AZ100: FM Navigator with flash card and GPS receiver for measurement campaigns. 

. AZ1000: FM Navigator in 19”rack with internal 115/230V power supply. 


AUDEMAT-AZTEC has incorporated into the AZ10, AZ100 and AZ1000 FM Navigators all the processing 
power necessary for DSP (Digital Signal Processing) of the FM sub-carriers (Stereo, RDS, DARC), the 
measurement of the RF signal, the measurement of the power of the FM multiplex signal, the accurate 
evaluation of deviation overshoots, etc... 


The FM Navigator has incorporated and improved all the functions of the decoding and display of RDS data 
that you may be familiar with from the AZ1 RDS Monitor product, developed by AUDEMAT-AZTEC several 
years ago. 


The rotary wheel, buzzer and battery (optional) provide the FM Navigator with the ergonomics essential for 
measurements in the field, in the car, and at difficult transmitter sites. The advanced integration of the 
electronic functions, thanks to the large memory capacities results in a portable, light and integral product. 


The location of the measurements by GPS and their storage in FLASH memory, in ASCII format, on PCMCIA 
card medium make the AZ100 model an extremely practical portable unit for use in measurement campaigns 
which can now be carried out without a portable PC. 

The purpose of this user guide is to allow you to familiarize yourself with your new equipment and discover 
all of its functions.

To modify a parameter, press ‘Enter’ to go into modification mode. A ‘= or “: sign flashes and the wheel is 
used to modify the value. A second press on 'Enter' locks in the new value. The parameters having only two 
possible values change value each time the ‘Enter’ button is pressed. 

All the modifiable parameters are saved in non volatile memory unless otherwise stated in the menu 
descriptions. 


4.3 The frequency memories menu (SHORT depression of the PGM button) 


The FM Navigator can save up to 50 frequencies in non volatile memory. Wherever you are in the menus, a 
short press on the ‘PGM’ button enters the frequency memory menu. A memory can be chosen by using 
the wheel. Another short press on 'PGM' returns you to the main menu. 

To modify a memory, select it and press ‘Enter’. The ':' sign flashes and you can change the frequency by 
using the wheel. Press ‘Enter’ a second time to save it. Between the value 108.0 and 87.5 is an ‘EMPTY’ 
value that clears the selected memory.

lash! The brightness is adjustable from level 1 to 7. 


BRIGHT: 7 | 








The 4 available modes are : 

* STEP: The frequency changes in steps of 100 kHz. 
* FM: scan + stop on all the FM stations. 

* RDS: scan + stop on the RDS stations. 


* DARC: scan + stop on the stations transmitting DARC. 
Caution, DARC detection can only be performed correctly if 
the type of DARC frames is defined to the required value 
(see corresponding configuration menu). 














RDS error correction can be enabled or disabled by 
pressing the ‘Enter’ key. This parameter is not saved. Error 
correction is disabled by default. 





Selects the type of DARC Frame to decode. This 
information is very important for the error rate. 

Note: this function is also available and more practical in the 
main menu, "DARC: 1/0" display. 








This menu filters the reception of paging messages by 
giving a group code to the receiver. This code is from 0 to 
99. Between 99 and 0 is a value ‘ALL’ which disables the 
group code filter (all of the paging messages are then 
decoded by the FM Navigator). 











lash! This menu filters the reception of paging messages by 


Y giving an individual code to the receiver. This code is 
IC: 5328 | between 0 and 9999. Between 9999 and 0 is an ‘ALL' value 
which disables the individual code filter.

IMPORTANT: Validity of the measurements. The level measurements (whatever the type) must only be 
taken as valid when the RF level on the observed frequency is greater than 60dBuV and on the assurance 
that no multipath phenomenon is present during the measurements. 


€ To choose the reception frequency 











CE” lash! This function is always accessible unless the Navigator is 
Y set to BNC input (see advanced configuration, above). The 
FREQ= 96.4 | Enter FREQ= 96.4 | display will alternate between frequency and RDS PS. 





YÉ To evaluate the signal level received on the antenna input 


Displays the RF signal level in dBuV (as seen at the antenna input of the FM Navigator). 

The audio output is normally muted during the display and measurement of the RF level. 

The audio output can be forced on by pressing the “Enter" button, some interference in the audio is usually 
perceptible under this condition. 

Do not forget to add 20dB to the indicated value if you are using the 20dB external attenuator! 

The RDS and DARC signals are also affected by this function. 


IMPORTANT: we recommend to use the +20dB attenuator whenever a 
signal over 90dBuV can be observed at the input of the navigator: better 
performances are obtained if the Navigator input is protected against very 
high signals. Use of the attenuator is also recommended on transmission 
Sites or in towns where the entire FM spectrum is full with high signal 
levels (when making a measurement campaig 











YÉ To display the deviation generated by the FM multiplex signal 


MPX: 68kHz j Displays the peak level (max) observed over 1 second, thus about 500000 samples performed by the FM 


Navigator in this time interval. 








NOTE1: to evaluate the intrinsic level of the pilot, RDS and other sub-carriers, use the corresponding menus 
and not this menu. Indeed, the maximum accuracy of the multiplex deviation, by design, at 75KHz, means that 
the small deviations (less than 20KHz and notably the sub-carriers) will inevitably contain some inaccuracies. 
NOTE2: RF level must be stable and no noise must occur for MPX measurements. RF value of 60dBuV is 
recommended. MPX observations are generally useless when mobile : perform MPX measurements in sable 
conditions : roof antenna or vehicle stopped and direct field reception. 





YÉ To display the FM multiplex signal power: CCIR conformity 





lash! Displays the multiplex average power over 1 minute, in accordance with the UER recommendation n°450-1. It 
is a rolling average, over one minute, measured by DSP ( digital signal processing). The higher the indication 
PMPX-4.5 | is, the more dense the signal and audio. 


Modulating with a continuous sinusoidal signal to a deviation of +/- 75 kHz will produce an indication of 





+11.9dB. The unit (dB) flashes when the indication does not conform with the recommendation (1 minute not 
reached). Wait 1 minute to obtain a accurate measurement.

4.9 NAVIGATOR 100 : measurement campaigns 


The following menus permit measurement ‘campaigns' to be conducted. No PC is required to counduct a 
measurement campaign. The measurement campaign data is stored in the 8Mb FLASH memory card 
plugged in to the back of the unit. 


The analysis of the measurement campaigns is done by means of the FM Explorer software which permits 
the memory card to be read directly from the FM Navigator. 


The measurement campaigns are stored in the memory card in the form of tabulated text files. The data can 
be exported by using the FM Explorer software to generate files compatible with many different programs, or 
imported into MapPoint with the included DLL. 


NOTE : if a measurement campaign is started without flash card, the data is directly sent to the serial port : 
19200 bit/s, 8 bits, no parity, 1 stop bit. 


IMPORTANT : if the FM Navigator power supply is turned off during a measurement campaign, the 
campaign will restart, with a blank file name, when power returns.

5. NAVIGATOR 1000 Navigator 


The FM NAVIGATOR 1000 is build upon an FM NAVIGATOR 10 core, with additional functionalities for 
switching applications. Depending on sub-carriers (audio, stereo, RDS, DARC) compared to preset 
thresholds, relays can be switched ON or OFF. 


5.1 NAVIGATOR 1000 main features 


rack 19" 1U mounting 

230/115 VAC integrated power supply 
signal detection on one particular frequency 
5 relays output (DB15 female) related to : 


RDS detection 

Stereo detection (pilot tone) 
RF detection 

AUDIO detection 

DARC detection 


VVNNN 


e signaling LEDs indicating the relay status on front panel 
e headphone output on front panel 


5.2 Detectors configuration 


5 detectors have been implemented in the NAVIGATOR 1000 versions: 


RF detector 

AUDIO detector (L+R signal detection) 
PILOT TONE detector 

RDS detector 

DARC detector 


VVVVV 


The output of each of these 5 detectors are directed to : 


- a RELAY output (20mA, 24V, isolated, SPDT common / N.O./ N.C). 
-ared LED placed on the front panel of the AZ1000 Navigator 


Each of these 5 detectors can be set from the front panel and/or from the serial link 
with the following parameters: 
- DELAY before detection (_TO extension as Time Out, given is seconds), 
DELAY=0 means no detection 
- THRESHOLD of action ( _TH extension for RF and AUDIO only, no threshold for RDS, PILOT TONE 
and DARC detection which are yes/no binary)

5.3 Relays Output 


Relays are connected through the SUBDB15 female connector placed at the rear panel of the unit.

12 RDS Common 
13 PILOT Normally Closed 
14 PILOT Normally Open 
15 AUDIO Common 





5.4 Signaling LEDs 


The 5 LED indicate the relay status, these LED are red when an alarm condition is set meaning that a 
relay is NOT ‘on’. 


When LEDS are flashing instead of solid, it means that: 


- the CONTROL operation has been stopped via the front panel or an RS232 request or 
- the AZ1000 has just been turned on : then you must wait until the CTRL TO delay has elapsed 


5.5 FAQ: frequently asked questions 


Q: | have set CTRL_TO to 240 seconds (4 minutes)... | do not want to wait this time each time | 
check if the control operation is working. How can I force the control operation immediately? 


A: Enter in the “RELAYS?” menu, then “EXIT REL?” indication appears, press Enter to exit the menu, in 
this case, the control operation will take place immediately instead of CTRL_TO seconds. 


AUDEMAT-AZTEC sa — AUDEMAT-AZTEC Inc 
WEB : www.audemat-aztec.com - e-mail : [email protected] 
Page 33/57 


Q: | hear glitches in the headphone when the control operation is active, what is the problem? 


A: If you have programmed the AZ1000 to verify the RF level (RF_TO<>0 and RF_TH<>0) : when the 
FM Navigator (AZ10, AZ100 and AZ1000) performs a RF level measurement, the RF input attenuator is 
activated during the measurement, that causes the glitch. When the AZ1000 is placed in a high RF field, 
this glitch is not heard because the input signal is high enough to enable good reception whatever the 
input attenuator value. 


Q: lam anxious about the fact that if somebody touches the front panel the control operation can 
be turned off or an or an alarm inadvertently triggered. Am I right? 


A: No! When somebody plays on the AZ1000 front panel and, for example, listens to other FM stations 
or checks RDS parameters on other frequencies, the relays are simply frozen during this manual 
operation. After the CTRL TO timeout, the control operation will resume automatically on the frequency 
programmed in setup program P1. This feature enables you to use the AZ1000 on site for other 
purposes, and it will automatically return to checking parameters on the programmed station. 


Q : I do not like relays, | would like to put the AZ1000 on my SNMP network on site. 


A: We advise you not choose the AZ1000, but choose the FMTEL5 which has Network Ethernet 
connectivity. With the FMTELS from AUDEMAT-AZTEC , you get a TCP/IP oriented solution with FTP, 
TELNET and SNMP features.

6. Operation from the RS232 COM port 


6.1 To connect a PC to the COM port of the FM Navigator 


A PC can be connected to the Navigator via the SUBD9female connector, labeled "RS232", situated on the 
rear panel. Locate an unused communication port on your computer. If the free port has a DB25 connector, 
use a SUBD9 (male) to SUBD25 (female) adapter. Do not use the port assigned to the mouse. Connect the 
open communication port of your computer to the port of the FM Navigator with a RS232 cable (not crossed), 
or A USB-RS232 adapter, if your computer has only USB ports. 


6.2 Choosing a "terminal" application and principles of ASCII communication 


To communicate directly with the FM Navigator, AUDEMAT-AZTEC recommends the use of an ASCII 
terminal running in MS-DOS® or Windows”. 

The terminal program included in Windows has all the characteristics to communicate easily in ASCII mode 
with the FM Navigator. If you require a higher level interface, AUDEMAT-AZTEC offers the FM Explorer utility 
which is available on Internet and can be used freely (no license required). FM Explorer is an utility which

Before moving on to examine the numerous commands which are available, the following explains the 
structure of the FM Navigator's ASCII command interpreter: 


The FM Navigator's ASCII command interpreter obeys the following rules. Any instruction sent, must be 
validated by «Enter» (chr$(13)). The character chr$(10) is ignored by the interpreter. 


If the command entered meets with success, the character ‘+’ followed by one or several line returns is sent 


back by the FM Navigator. In the case of a failure (command not understood or parameter incorrect) the 
character ‘! is sent back in a similar fashion.

6.4 ASCII protocol: measurement instructions 


Certain measurement instructions send a continuous stream of data. In this case, the front panel of the FM 
Navigator is locked and the display shows « RS232 BUSY ». The incoming data stream can be stopped by 
simply sending the character <ESC> (chr$(27)) or «CR» (chr$(13)) via the serial interface. A second option 
is to press the 2 buttons on the front panel simultaneously; the FM Navigator returns to the operating mode 
indicated on the front panel and stops the data stream. 


Instruction syntax Description of the instruction 
Navigator 10, 100, 1000 


The M instruction returns a decimal number between 0 and 255 representing 8 status bits : 
- bit 0: not used. 
- bit 1: stereo presence. 
- bit 2: TP. 
- bit 3: TA. 
- bit 4: M/S. 
- bit 5: not used. 
- bit 6: RDS presence. 
- bit 7: DARC presence. 
Output of the RF level in dBuV in constant stream (approximately 1 measurement per second). Each 
measurement is separated by a line return (CRLF). During these measurements, the audio output is in 
silent mode and the RDS and DARC channels can be disrupted. Send the «Esc» or «CR» characters to 
stop the operation or press the two buttons on the front panel simultaneously. 
*PWR PEAK Output of the multiplex power and the number of continuous multiplex overshoots. 2 components are 
— transmitted every second, as follows: 
[#]<MPX power>chr$(9)< MPX overshoots (ppm)<CRLF> 


As shown in the menu list, these two measurements require 60 seconds before being able to give a value 
conforming to the CCIR recommendation n°450-1. The validity of the measurements is shown by the 
disappearance of the # opposite the measurement lines. 

Example: 


- Measurements not valid : #9.5<chr$(9)>1333<CRLF> 
- Measurements valid : #-0.4<chr$(9)>0<CRLF> 


Continuous output of the FM multiplex signal deviation value in kHz. 


Continuous output of the level value of the left channel plus the right in %. 
Continuous output of the level value of the left channel minus the right in %. 
Continuous output of the level value of the left channel in %. 


Continuous output of the level value of the right channel in %. 


“57 Continuous output of the 57KHz sub-carrier deviation value in kHz. 
76 
E EEE izi 


INIT Re-initializes the FM Navigator with the "factory set-up" parameters including the decoding and DARC 
related parameters. 





NOTE for the functions “MPX till “76 : the character "" can be replaced by '#' in order to return only one 
value instead of a constant data stream.

6.7 ASCII protocol: NAVIGATOR 100 instructions for downloading of measurement 
campaigns 


It is easiest to download the measurement campaigns from the FLASH memory card to a PC by using the 
FM Explorer software. You can also download send the contents of the FLASH memory via the serial 
interface by using the ASCII protocol instructions which follow. 


Instruction syntax Description of the instruction 
Navigator 100 


= CGN_SCAN=OFF 
CGN_SCAN= CGN_SCAN=FM 

CGN_SCAN=RDS 

CGN_SCAN=PGM 


Sets the operating modes described in the man machine interface of the CGN MES? display menu SCAN 
menu 


ee Defines the next campaign title 
CGN TITLE= 


= |CGN MODE=SLOW 
CGN MODE= CGN MODE=FAST 


Uses the operating modes described in the man machine interface of the CGN MES? Display menu, 
MODE menu 
For NAVIGATOR 100 : Specifies that the FM Navigator must read all the " measurement campaigns" 
information stored in the Flash memory and to send this information in ASCII format via the RS232 COM 
DL CGN port at the speed of 19200,N,8. 

— Enter DL_CGN<CR><LF> in 9600,N,8,1, then turn on 19200,N,8,1, then <CR><LF>, then listen at 19200 
the serial port... end of download is mentioned by 2 successive <CR><LF> (<CR><LF><CR><LF>) 
For NAVIGATOR 10 : triggers the measurement campaign, the data is outputted on the serial interface, 
the campaign is stopped by the reception of a CRLF sequence via the serial interface or by a long 
depression of the <Enter> button 


Returns the main GPS data (Longitude, Latitude, speed, time, date, altitude and number of satellites) if 
available. The format is the same as the first seven fields of the measurement campaign. 

The line is terminated with <CRLF>. 

If the GPS data are not available, the message 'NO GPS!' is returned. 





The output data of a measurement campaign is transmitted in the form of lines of text each representing a 
group of associated measurements. The end of a line is marked by a «CR» «LF» "chr$(13)+chr$(10)". The 
data fields on a line are separated by a tabulation character "chr$(9)". Certain data fields contain several 
bytes of data which are then separated by a semicolon "chr$(59)". 


If a data field is not available, such as GPS during the passage through a tunnel or the PI code of a non RDS 
station, it is left empty. 


The FM Navigator has two measurement campaign modes, the fast mode, which only records 10 fields per 
measurement line, and the slow mode, which adds about twenty additional fields to the first ten. The slow 
mode requires a relatively long analysis time for each station (approximately 5 minutes) and is not advised in 
a moving vehicle.

APPENDIX 2: FM CALIBRATED ANTENNA 


2.1 RF Field measurement 


The NAVIGATOR 10/NAVIGATOR 100/NAVIGATOR 1000 equipments provide measurement of RF signal 
amplitude on its BNC socket input. Therefore the unit of RF measurement either on the front Led display or 
on the FM Explorer software is in dBuV. 


For real-world measurements and coverage evaluation it is more desirable to get RF field strength 
measurements. This is possible using the calibrated antenna included with the Navigator 100. 


Compatibility starts with FM Explorer: V7.0.1. 


2.2 RESTRICTIONS 


The CCIR specifies the conditions of normalized measurements. These specifications include that 
measurement have to be done at 10 meters above ground level. This condition is obviously not 
compatible with measurement using moving vehicle, and is the main restriction to measurement 
campaign you can acquire with NAVIGATOR 100. 


The calibrated antenna has been approved in C2R laboratories a branch of French national 
broadcaster TDF. The conditions of antenna use are critical to the validity of the calibration. The 
antenna is supposed to be placed on a metal roof of a car. The antenna should be placed in a center 
of a metal surface with a minimum size of 1 m2. Any other antenna nearby (roof car antenna) will 
affect antenna measurement accuracy. Plastic, fiber or composite material vehicle roof is prohibited. 


The antenna cable along with its connector is part of the delivered antenna and their characteristics 
are taken in account in the measurement conversion process. If the cable is changed or modified the 
measurement accuracy will be affected. 


The guaranteed accuracy on field measurement is +/- 4dB providing strict respect of above 
statements.

2.3 How to configure FM Explorer for real time field measurement? 


The antenna selection is a general setting of FM Explorer. The activation of field conversion can be selected 
or disabled in different measurement displays, 


With "browse", select the calibration file of the antenna.

2.5How to configure FM Explorer for field measurement with campaign 


The conversion to RF field strength readings takes place when you save a campaign, after downloading from 
the NAVIGATOR 100 Flash card. 

The same downloaded campaign can be saved with and without the conversion to dBuV/m. 

The antenna type used is the one selected in the general FM Explorer settings as described in the previous 
section. Any change of the antenna selection will affect general FM Explorer setting.

After the download of the measurement campaign, select the option "convert dBuV into dBuV/m" in order to 
save the data as field strength measurements. 


The exportation of the measurement campaign to Microsoft MapPoint can then be done as described in the 


previous chapter.
