DSA-200P
Terrestrial FM/DMB/DTV Broadcasting Signal Analyzer
This equipment is a signal analyzer specialized in measuring FM broadcast signal quality.
In addition to the FM signal analysis function, it also provides DTV signal analysis function, DMB signal analysis function, and general spectrum signal analysis function as options.
It is a measuring equipment that is easy to carry due to the use of high-performance integrated circuits and a lightweight design of 5 kg. In addition, it has improved user convenience through various functions such as a wide touch screen and automatic measurement and report generation.
