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 characteris-
tics 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 characteris-
tics.

2.1 General
The field strength meters 7849B-7859B-7817B are appliance designed for the installation and maintenance
of any broadcasting and reception installations of analogical and digital terrestrial television channels, satel-
lites or cable networks, for RF or optical modulated signals.
The band ranges between 5 MHz to 2400 MHz; this allows accurate measurements on all analogical televi-
sion standards, FM carrier waves and the various digital standards DVB-C/C2, DVB-T/T2/T2Lite, DVB-
S/S2/S2X and DSS.
They do Level measurements in average, peak and power according to the selected standard
In Measurement Plan mode, they scan up to 50 setups at the same time and compare them to decision lev-
els (min / max).
Equipped with an efficient Bit Error Rate measurement (various BER, MER), they allow the full validation of
digital transmissions DVB-T/T2/T2Lite, DVB-C/C2, DVB-S/S2/S2X and DSS.
Providing a Constellation diagram for digital standards, the detection and display of Multipaths permit to
complete this analysis.
You can display the digital terrestrial or satellite TV (free programs) under SD or HD.
You can hear digital sound through integrated loudspeakers.
The 7859Bhas an Optical input (optical head, FTH cable): it integrates an optical power measurement and
an optical-to-RF converter in the Field Measurer band.
The 7817B has a special "One-Touch" feature designed to qualify the installations of subscriber broadcast
networks.
Designed for use on field, they are compact (less than 2 kg battery included), autonomous (battery pack and
quick charger), equipped with a LCD 7’’ touchscreen (capacitive).
The high memory content allows the storage of many configurations, measurements and spectrum curves.
The appliances fully remote-controlled through USB and ETHERNET connections via a computer.
