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
preservation 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.

2 Quick start-up
2.1 Presentation of the appliance
Important keys:
788X 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 :
Some parameters can move ‘step by step’ : use arrows on each side of the value.
Frequency example :
You may also access tables by pressing lines (on white or yellow)
Attention: To exit a window like in this example below, press the key:
Press button ON/OFF
RF connector for use with an
F/F adaptor provided with the
appliance.

2.2 Signal spotting
The 788X allows spotting signals in terrestrial or satellite very quickly.
In the following chapter, we will see how to spot a 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 Checking a terrestrial antenna
In this case, the “Autoset”function allows a “scan”of the channels that the antenna detects.
Plug the cable of your antenna to the 788X (take care to use an adequate adaptor)
Turn your appliance on.
Press the “Home”key , then choose the tab “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 E2 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)
Press “START”, the appliance starts a search.
At the end of the scan, it turns directly to the “Measurement Plan”mode. If channels were found, the
appliance makes measurements continuously (level, C/Nl, BER/MER) on the detected channels.

–788x –
p. 14
Eventually, press the “Measures/TV/Spectrum” key; on this new page, select the channel that you want to
display.
The instrument display on a single page of parameters of the signal, TV picture and Spectrum scan : a great
time gain for your installs.
2.2.2 Installation of a terrestrial antenna
To install a terrestrial antenna, two ways are possible :
Spectrum function use
Pointing function use
2.2.2.1 Using Spectrum function
Plug the cable of your antenna to the 788X (take care to use an adequate adaptor)
Turn your appliance on. Press the “Measures-TV-Spectrum”key
Press the “Spectrum”area
Access to full SPAN mode

–788x –
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/TV key , the device find automatically all the parameters of the signal.
Once the search ended, the device display TV picture, TV name, “Network Name” and “Network ID”.
Press the “Measures-TV-Spectrum”key. You can now display the level, the BER/MER, the TV picture (with
information about the current service) and the spectrum of the signal selected on the same page…

–788x –
p. 16
2.2.2.1 Using Pointing function
The device has a terrestrial pointing function to quickly and easily adjust your terrestrial antenna.
Access the terrestrial pointing menu from the "HOME" page by pressing the key« Pointing »
, puis « Terrestrial »
The following page appears :
Choose the transmitter to point in the list
If your transmitter is not in the list, if you want to enter a new transmitter, please refer to chapter 9.1
Once you have completed the four channels, turn the antenna slowly until you hear the melody and get the
maximum quality
No channels found → Red Smiley
Average reception quality → Orange smiley
Good reception quality → Green Smiley

p. 17
2.2.3 Installation of a satellite dish
To install a satellite antenna, two ways are possible :
Spectrum function use
Pointing function use
2.2.3.1 Using Spectrum function
Connect the satellite dish to the appliance.
Activate the remote power supply
To access to the Remote power supply page, press “Home” and then “LNB-DISEQC”
Press key « Measures-TV-Spectrum »
Press the “Spectrum”area (see below)
Access to full SPAN mode

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/TV key , the device find automatically all the parameters of the signal.
Once the search ended, the device display TV picture, Satellite name, and “Network ID”.
Press the “Measures-TV-Spectrum” key. You can now display the level, the BER/MER, the TV picture (with
information about the current service) and the spectrum of the signal selected on the same page…

p. 19
2.2.3.2 Using Pointing function
The device has a satellite pointing function to quickly and easily adjust your dish.
Access the satellite pointing menu from the "HOME" page by pressing the key« Pointing »
, then “Satellite”.
The device proposes to activate the remote power supply :
The following page appears:
Check the indication of consumption on the remote power supply; zero consumption
indicates a failed LNB, or a cut coaxial cable, for example.

–788x –
p. 20
Select a satellite like in the example below (here Astra1):
If your satellite is not in the list, if you want to enter a new satellite, refer to chapter 9.2.
Slowly orientate the satellite dish until hearing the locking melody and getting the best quality
No found transponder → red smiley
Average reception quality → orange smiley
Good reception quality → green smiley
Reminder: transponder = satellite channel
