General
-The
7859
field measurer is a handy appliance designed to qualify and maintain all RF or optical installations
RF for broadcasting and receiving analogical and terrestrial digital, satellite or cable network television chan-
nels.
-The band ranges between
5 MHz and 2200 MHz;
this allows accurate measurements on all analogical tele-
vision standards, FM carrier waves and the various digital standards DVB-C/C2, DVB-T/T2/T2Lite, DVB-S/S2
and DSS.

mode, they scan up to 50 setups at the same time and compare them to decision
levels (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 and DSS.
