General

The field strength measurers FSM-640 are handy appliances designed for the installation and maintenance
of any broadcasting and reception installations of analogical and digital terrestrial television channels,
satellites or cable networks.
The band ranges between 5 MHz and 2200 MHz; this allows accurate measurements on all analogical
television standards, FM carrier waves and the various digital standards DVB-C, DVB-T/H, DVB-T2, DVB-
S, DSS and DVB-S2.
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
levels (min / max).
Equipped with an efficient Error level measurement (various BER, MER), they allow the full validation of
digital transmissions DVB-T/H, DVB-T2, DVB-C, DVB-S, DSS and DVB-S2.
Providing a Constellation diagram for DVB-T/H, DVB-T2, DVB-C, DVB-S, DSS and DVB-S2, and the
measurement and display of Echoes and pre-echoes in DVB-T/H et DVB-T2 to have a complete analysis of
the digital signal.
You can measure and display of MER per carrier .
You can display the digital terrestrial or satellite TV under SD or HD.
The Measures-TV-Spectrum mode allows the simultaneous display of the spectrum measurement and of the
video of the one same signal.
A HDMI socket allows the transmission from HD video to TV.
You can hear digital sound through integrated loudspeakers.
Designed for use on field, they are compact (less than 3 kg, battery included), autonomous (battery pack
and quick charger), equipped with a LCD 10'' touchscreen (capacitive).
The high memory content allows the storage of many configurations, measurements and spectrum curves.
Each appliance is fully remote-controlled through USB and ETHERNET connections via a computer.
