METROLOGY
The meteorological conditions of your measurement instrument are defined in the specifications of this notice. Climate and
environmental conditions restrict the specifications of your Field Strength Measurer (MDC). SEFRAM checks the characteristics
of each appliance one by one on an automatic bench during its manufacture. The adjustment and control are guaranteed under
conditions of the ISO9001 certification by facilities in connection with the COFRAC (or equivalent in the context of ILAC
reciprocity).
The specified characteristics are considered stable for a period of 12 months from the first use under normal conditions of use.
We recommend a check after 12 months and max. 24 months of use, then every 12 months after 24 months.
For any check of the characteristics, the following average climate conditions shall be maintained (23°C+3°C –50(+20)%RH).
The MDC should have been working for 0,5 hour before check.
We recommend that you have this control made by our after-sales service (Service Après-Vente) for the best service and preser-
vation of the measuring quality of your instrument.
When a MDC returns to SEFRAM, maximum service is provided with internal updating according to the required adjustments
and software updates. In case of shift in the characteristics, your instrument shall be adjusted to recover its original characteristics.
PACKAGING
The packaging of this product is fully recyclable. Its design allows the transport of your instrument under the best possible
conditions. Please note that the original packaging should be additionally wrapped in case of transport by air, road or postal.
SPARE PARTS
According to the consumption law of March 17, 2014, Article L111-3 and Decree 2014-1482 of 09/12/2014, SEFRAM in-
forms you of the availability of spare parts of products placed on the market as of March 1, 2015:
Spare parts are not available to the consumer. SEFRAM offers the supply of spare parts during repair by its service.

p. 11
2 Quick start-up
2.1 Presentation of the appliance
To plug the appliance for optic measurements, refer to the paragraph 19.1 Presentation of the optic meas-
urement
Important keys:
7859 is an appliance with a capacitive touchscreen. This requires a soft handling. No glove and no stylus
should be used, so that the triggering should be taken into account.
You will recognize the « keys » by their dark grey color (example: the home key: )
You may also access tables by pressing lines (on white or yellow)
Welcoming page:
button ON/OFF
RF connector for use with the
F/F adaptor provided with the
appliance.
Pour brancher le signal à analyser
Gives you access to the using mode (RF or optic)

–7859 –
p. 12
Attention : To exit a window like in this example below, press the key:
2.2 Signal spotting
The 7859 appliance tracks very quickly RF or optical terrestrial or satellite signals.
In the following chapter, we will see how to spot a RF signal on three types of installation:
Checking of a terrestrial antenna (the installation has already been made).
Installation of a terrestrial antenna.
Installation of a satellite dish.
2.2.1 Scanning a terrestrial antenna in RF mode
In this case, the Autoset function allows a scan of the channels that the antenna detects.
Plug the cable of your antenna to the 7859 appliance (WARNING: use an adequate adaptor)
The antenna shall be previously adjusted to a terrestrial emitter.
Turn on your appliance. Press RF/Optic
Press Entrée RF
The Home page appears on screen. Press Autoset
On this page, press Mode, Terrestrial, then select DVB-T and 8MHz (as here below)
The scan should range from the E21 to the E69 channels, frequency range Europe (you may reduce the
number of channels to scan if you know the range of the emitter where the antenna points at: the scan will
be faster)

–7859 –
p. 13
Press START. The appliance searches until the end of the scan and turns directly to the Measurement plan
mode. If channels were found, the appliance makes measurements continuously (C/N-level, then BER/MER)
on the detected channels. If no channel has been found, see the next chapter.
To finish, press the home measurement key then on , On this new page,
press Prog, select the channel that you want to display.
Check the level, the BER/MER, the TV detection and the spectrum of the signal on this page…

–7859 –
p. 14
2.2.2 Installation of a terrestrial antenna
You have two methods to install a terrestrial antenna:
Use of the spectrum
Use of the satellite dish
2.2.2.1 Use of the spectrum
Plug the cable of your antenna to the 7859 (take care to use an adequate adaptor)
Turn your appliance on. Press the Measures-TV-Spectrum key
Press the Spectrum zone, access to terrestrial mode if needed
Access to full SPAN mode

–7859 –
p. 15
Adjust the antenna to get the most powerful signal possible
Press directly the signal you want in the spectrum (the cursor moves to where you press)
Press the NIT key , the device find automatically all the parameters of the signal.
Once the search ended, the device display the “Network Name” and the “Network ID”.
Press the Measures-TV-Spectrum key. You can now display the level, the BER/MER of the signal selected
on the same page…

–7859 –
p. 16
2.2.2.2 Use of the Antenna pointing
The appliance gets an “Antenna pointing” mode in order to align quickly and easily your terrestrial antenna.
To access to the “Antenna pointing” mode from the HOME page, press
The following page appears:
Set your emitter name:
Enter 4 frequencies of the emitter you want to check.

–7859 –
p. 17
You can find many different French transmitters in an Excel file available on the website of
SEFRAM (download section, then database transmitters TNT) or by clicking under the fol-
lowing link:
http://www.sefram.com/telechargement/fichier-de-configuration.html

–7859 –
p. 18
Slowly orientate the antenna until hearing the locking melody and getting the best quality
No transmitter found, bad reception quality → red smiley
Average reception quality (< 50%) → orange smiley
Good reception quality (> 50%) → green smiley
2.2.3 Installation of a satellite dish
Connect the satellite dish to the appliance.
Activate the remote power supply
To access to the Remote power supply page, press
To switch on the remote power supply, press then select ON in the page to launch the remote
power supply:

–7859 –
p. 19
A green check appears in front of what you validated
Press then and access the Check Sat mode.
(the appliance already includes a list of satellites).
Select a satellite like in the example below (here Astra1):
Slowly orientate the satellite dish until hearing the locking melody and getting the best quality
No found transponder → red smiley
Average reception quality (< 50%) → orange smiley
Good reception quality (> 50%) → green smiley
Reminder:transponder = satellite channel

–7859 –
p. 20
To check if the aimed satellite is the right one: press the NIT key
The appliance searches the MPEG NIT table on one of the 4 transponders and displays the name of the
satellite:
Attention:
To identify a satellite, you must be locked on all 4 transponders. (Quality > 0)
However, some transponders are regularly modified. See the frequency range of the
satellite when a transponder does not seem to work.
Some switches or LNB work only with DiSEqC commands. In this case, position the
band (OL) and the polarization on DiSEqC at the Configuration page LNB-DiSEqC.
(Attention: the Check Sat is slower when using the DiSEqC command).
Attention: The displayed name depends on the content of the MPEG NIT table.
Some distributors provide no (or poor) such table.
The displayed information may be wrong.
