DSO Coral (112A) is an upgraded model of DSO112 (see DSO112) with re-designed schematic and PCB. Due to the new design this oscilloscope becomes more accurate and reliable. As high as 2mV/div sensitivity and ultra low background noise made the device particularly useful for measuring weak signals. Up to 24 presets with customizable titles allow setups be retrieved in seconds. While keeping all performance of DSO112 this new model brings in the following improvements:
