DSO112A Upgrade Version 2MHz Touch Screen TFT Digital Mini Handheld Oscilloscope

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.
