DSO112a Coral is a pocket oscilloscope with color display and touch
panel. DSO Coral (112A) is an upgraded model of 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:

* Maximum sensitivity was increased to 2mV/div (older version is
5mV/div) with lower background noises.
* Fixed the vertical position mismatch problem found in the older
* Save/recall up to 24 parameter presets. This allows quick setup
for frequently performed measurements.
* Preset titles can be customized for easy remembering and
* Expanded and improved on-screen measurement displays which include
frequency, Vmax, Vmin, Vavr, Vpp, and Vrms.
* Added external trigger feature.
* Provided a two-way serial control interface which can output
data/measurements and receive commands. This will make the device
suitable for integration to customer applications.
* Replaced out-dated miniUSB connector with more popular microUSB
* Enclosure strength enhanced.
