JYETech DSO Coral Pocket Battery-Powered Oscilloscope w/Color Touch Display (DSO112A)

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:

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 model.

Save/recall up to 24 parameter presets. This allows quick setup for frequently performed measurements.

Preset titles can be customized for easy remembering and identifying.

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 connector.

Enclosure strength enhanced.
