ABSTRACT:
A handheld, battery operated network testing device uses disk loaded software, programmable gate arrays, and digital signal processing to selectively configure the device for a full range of analog and digital testing modes in a variety of communications protocols, including T-1 full duplex drop and insert. A 25 by 80 column LCD display provides for a full scale video output, and a unique, power efficient, electroluminescent backlight circuit provides for viewing of the display in poorly lit environments.
