JYETech 13805K DSO138 Mini Digital Oscilloscope 200KHz DC 3.5V-6V

DSO138mini brings in the following improvements: Better structure and smaller size. The bulky pin-headers connecting the LCD and main board in old DSO138 has been eliminated. The soldering of these pin-headers has being found problematic for beginners.USB or battery powered. This makes the scope much more convenient to be used as a portable device. New version analog board (PN: 109-13801-00H, aka "H version") can accommodate a battery charger JYE118 (see here) to make the device more practical.External trigger input. This input can accept a TTL or LVTTL signal as trigger source.Serial output of waveform data. This means captured data can be saved and displayed by PC. For example, this photo shows a captured single byte (0x35) sent from a serial port at 115200bps. This photo shows the same waveform displayed on PC using Gnuplot.General controller. The main board can be used as a general purpose control board with LCD display. MCU ports were brought to board edges for easy connection to the target system. There are a few optional parts that can be chosen to make the oscilloscope even more complete: BNC connector. The kit comes with a two-pin header for the simple hook probes (see the manual). This connector replaces the two-pin header and will allow you to connect to standard professional BNC probe.Standard BNC probe.Major features of DSO138mini: Analog bandwidth: 0 - 200KHzSampling rate: 1Msps maxSensitivity: 10mV/Div - 5V/DivSensitivity error: < 5%Vertical resolution: 12-bitTimebase: 10us/Div - 500s/DivRecord length: 1024 pointsExternal triggerBuilt-in 1KHz/3.3V test signalWaveform frozen (HOLD) function availableSave/recall waveformImportant Notes: The power supply is not included in the kit. User needs to prepare a USB cable with micro-USB style plug to run the scope. Any USB port with higher than 150mA current capacity can be used as power source for the scope.SpecificationsNumber of Channel1Analog Bandwidth0 - 200KHzSensitivity10mV/Div - 5V/DivSensitivity error< 5%Resolution12-bitInput Impedance1M ohmMaximum Input voltage50VpkCouplingDC, AC, GNDMax Real-time Sampling Rate1MspsTimebase10us/Div - 500s/DivRecord Length1024Trigger ModesAuto, Normal, SingleTrigger TypesRising/falling edgeTrigger Position1/2 of buffer size fixedDisplay2.4-inch color TFT LCD with 320 x 240 resolutionPower Supply3.5V - 6V DCSupply Current120mA @5VDimension85mm x 75mm x 15mmWeight50 gram (not including cables)Package includes:1 x Mini Digital Oscilloscope1 x User manual
