Digital Handheld Pocket Oscilloscope Kit 1MSa/s 200KHz Analog Bandwidth Support 80KHz PWM And Firmware Update       Description:  Note:This kit is fully soldered.But the diy case is not fully Assembled.The diy case must be assembled by yourself. This digital oscilloscope kit adopts ARM Cortex-M3 processor and with 2.4-inch TFT screen and protective case. It's easy and reliable for circuit operation. It can display waveform parameters, such as frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.  Features:  Adopt ARM Cortex-M3 processor (STM32F103C8), and include a 2.4-inch color TFT display screen. Used for secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers. Come with instructions, easy to install and operate. With Auto/Normal/Single trigger modes, easy to capture the moment waveform. Available rising or falling edge trigger. Observable previous waveform before trigger(negative delay). Can freeze waveform display at any time(HOLD function). With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values. Waveform storage function: will not lose the waveform after power off. Short-circuit and open-circuit detection: can help the user find out the soldering error. TFT controller recognition function. The SMD has been soldered, more suitable for electronic beginner.  Specifications:  Maximum Real-time Sampling Rate: 1MSa/s Analog Bandwidth: 0-200KHz Sensitivity Range: 5mV/div-20mV/idv Maximum Input Voltage: 50Vpk (1X probe) Input Impedance: 1M ohms/20pF Accuracy: 12 Bits Record Length: 1024 points Coupling Modes: DC / AC / GND Time Base Range: 500s/Div - 10us / Div Trigger Modes: Auto, Normal, and Single Trigger Position: Center of Buffer Supply Voltage: DC 9V(8-10V) Current Consumption:~120mA @ 9V Main Board Size: 94 * 65mm / 3.7 * 2.56in Analog Board Size: 65 * 47mm / 2.56 * 1.85in Screen Size: 52 * 40mm / 2 * 1.57in Package Size: 14.5 * 10 * 3.7cm / 5.7 * 3.94 * 1.45in Package Weight: 179g / 6.33oz  Package List:  1 * Fully Assembled Digital Oscilloscope Kit 1 * Probe 1 * DIY Case 3 * User Manual(English)
