概要（Overview）

AD920 is the first line of defense for critical MPEG error analysis. Its rugged casing and simple operation make it perfect for field use. Ideal for simple error checking, the AD920 monitors an ASI/SMPTE310M stream in real time giving graphical indication of stream associated rates, and counts errors as defined in TR101290 (formerly ETR290) First priority*1 testing. A log of errors is maintained on screen giving the user historical representation of stream associated errors.
