IT-082 provides convenient measurement of quality characteristics of digital satellite television reception.
IT-082 GENERAL FEATURES:
o lightweight and compact handheld design
o alignment of satellite dish with one or two (simultaneously) LNBs
o MER and BER measurement
o built-in beeper, level meter, MER, BER
o constellation diagram with ¼ zoom
o adjustment parameters automated determination
o LNB powering and DiSEqC 2.1 control
o data logger function enabling storage of:
· up to 50 LNB types;
· up to 100 satellites with transponder parameters;
· up to 100 measurement logs;
· up to 100 spectrum analyzer logs for with the adjustable span
o PC compatible (extra service modes, satellite specifications download, printing of reports and etc.)
o user firmware update
