Description : 

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


DSO112A 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.

Features :

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.

School after-school  teaching practice and student development of electronic small production.
Audio equipment  maintenance and  circuits, electronic toys and remote control model car electronic circuits.
On-site  repair common electronic equipment (air conditioning or industrial frequency power inverter, AC / DC switching power supply or inverter, elevator and building fire-fighting equipment, industrial control circuit).
Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other  communications interface circuits, LED display and keyboard scan driver circuit, brushless motor drive circuit.
Observing the slow signal changes needed for applications. (such as : relay and switch contacts jitter, battery charge and discharge curves, power supply load transient response characteristics of the temperature sensor measurements.)

Supply the electronic circuit. (SCR voltage regulator, power factor compensation, electronic energy-saving lamps, dysprosium lamp mercury lamp sodium lamp drive circuit xenon lights, etc.)  
Freeze at any time waveform display. ( HOLD function)
Unique  rolling slow signal display, the display can be fully continuous signal, unlike SCAN mode will cause the signal display discontinuous.
Time cursors, can automatically calculate and display the time difference.
Voltage cursors can automatically calculate and display the voltage difference.
Square wave test signal comes  1000Hz / 3.3V.
To  save / recall waveform acquisition.
PC upload waveform data.
