2 Introduction to the NORMARC 7710 NAV Analyzer
The NORMARC 7710 NAV Analyzer is used to adjust, verify and record parameters of ILS (Localizer, Glide Path,
Marker Beacon) and VOR ground systems. The NAV Analyser’s functionality substitutes instruments like ILS/VOR
receivers, modulation meters and frequency counters. It incorporates all ILS and VOR channels selectable
without any tuning or equipment changes. It facilitates measurement of
•ILS: Modulation Depth (DDM and SDM), RF level and Ident modulation level, Carrier and Audio
frequencies, 90Hz to 150Hz phase and harmonic distortion, Ident decoding
•Marker: Depth of modulation, Modulation frequency, RF level, Carrier frequency
•VOR: Bearing, Depth of modulation 30Hz, Depth of modulation 9960Hz, Ident modulation, RF level,
Frequency modulation index, Carrier frequency, subcarrier frequency, Ident decoding
The NAV Analyzer is a portable, battery-operated weatherproof unit to be used outdoors, in a vehicle or inside
the equipment shelter. It is supplied with a dipole antenna with a unipod support and coaxial cable. The analyzer
has a rough outdoor design and is protected against damage during transport.
The NAV Analyzer uses a digital radio with demodulation based on digital signal processing and with storage
functions. Full control from a remote system (typically a PC) by use of network technology is possible.
The user interface is a graphical display (GUI) with a corresponding keyboard on the front panel of the
instrument. Night condition is supported. Audio jack for Identity / Voice monitoring is incorporated.
It has a GPS and tachometer interface for ILS Localizer runway measurements.

3 Setting up the NAV Analyzer for the first time
3.1 Package contents
The package contents include the following items:
•NORMARC 7710 NAV Analyzer
•Battery charger w/std. European plug
•Handheld antenna mast with selectable dipoles
•Coax cable for the antenna
•Crossed network cable
•Soft bag for instrument and soft bag for accessories
3.2 Charging the batteries
The first thing to do is to charge the internal battery. Connect the battery charger to an electrical outlet, and
plug the other end into the rear of the NAV Analyzer.
Observe that the Power led after flashing quickly for a few minutes (trickle charge) changes to continues ON
status (charging battery).
If the led starts to blink the Morse code letter "S" - the voltage of
the battery cells is too low to start full charging. In this case, restart the charge cycle once every five minutes by
turning off and on again the external power until full charging starts.
Leave the instrument on full charge for at least 10 hours.

3.3 Connecting to RF signal
3.3.1 Using the supplied antenna
Connect one end of the coaxial cable to the antenna and the other end to the rear of the NAV Analyzer. Select
the correct dipole according to what you are measuring.
3.3.2 Using another RF source
Connect the source to the RF input at the rear side of the NAV Analyzer through an appropriate cable. Use the
supplied coax cable if suitable.
NOTE! Be sure not to overload the input. The specification for the input is max 0.1W (20dBm).
3.4 Turning the instrument on
a. Make sure that the battery is charged, or that the charger is connected
b. Turn on the power switch at the rear of the NAV Analyzer
c. Press and hold (1 sec) the [ Power ] – button on the front panel
3.5 Turning the instrument off
The instrument can be turned off into two different modes.
1. Totally off (Power LED is off)
a. Use the power switch at the rear of the instrument or
b. Press the [Power]-button and select the [Off]-button from the sub-menu

11
In this mode the instrument does not use any power.
This is the preferred mode if the instrument is not going to be used for several hours.
2. Sleep mode (Power LED flashes slowly)
a. Press and hold (2 sec) the [Power]-button until the screen turns off or
b. Press the [Power]-button and select the [Sleep]-button from the sub-menu
In this mode the instrument uses power to keep the main functions active. This allows for a much quicker restart
and for reactivating the menu that was active when the instrument was put into Sleep mode. A fully charged
battery will last for >18 hours in this mode.
This is the preferred mode during a measuring sequence when the instruments have to be turned off for moving
to a new measuring Location.
To turn the instrument back on again, press and hold (2 sec) the [Power]-button until the screen turns on.
3.6 Screen saver
To save power and thereby increasing the time the instrument can be used on battery, a screen saver is built-in.
To activate it;
a. Press the [Setup]-button and then select the [Screen...]-button from the sub-menu
b. Use the wheel (or up/down navigation buttons) to select how long to wait before it activates (1-120
minutes)
c. Set it to 0 minutes to disable it
When the screen saver activates, the screen will be blank but the Power LED will be on.
Any button or use of the wheel will bring the screen back on. Storing of data continues as normal when the
screen saver is activated.

12
3.7 Backlight
The intensity of the screen backlight can be set to suit the light of the surroundings.
a. When no input field is active, use the wheel on the front or
b. Press the [Power]-button and select the [Backlight inc] / [Backlight dec] / [Backlight off] buttons from
the sub-menu (Backlight off is the same as activate screen saver)
3.8 Connecting a computer to the NAV Analyzer
A computer (PC) may be connected to the NAV Analyzer for textual and graphical display of measurements,
storage of log files and maintenance of the instrument.
The connection can be made using the standard network connector, Located at the rear of the instrument.
To connect directly to a PC, use the included standard crossed network cable.
If using a network switch or router between the computer and the instrument, you may use a ordinary network
cable, since most switches/routers have auto-sensing for the network connection.
For setting up the instrument refer to 5.6
