Hengjiaan DSO138 Portable 2.4 TFT Digital Oscilloscope DIY Kit - Red
.sku-text{font-size:13px;width:898px;margin:5px 0;font-family:'Verdana';} This DSO138 digital oscilloscope kit adopts ARM Cortex-M3 processor and with 2.4-inch TFT screen. It's easy and reliable for circuit operation. It can display frequency£¬ period£¬ pulse width£¬ duty ratio£¬ MAX./MIN./AVG./Peak-Peak/virtual values. Features: This kit uses ARM Cortex-M3 processor (STM32F103C8)£¬ and includes a 2.4-inch color TFT display screen£¬ can be used as ARM test development board. Can be secondary development on the basis of this kit£¬ for example£¬ it can be changed to Millivoltmeter£¬ data loggers. Adjustable vertical displacement£¬ and with instructions. With automatic£¬ regular and one-shot modes£¬ easy to capture the moment waveform. Available rising or falling edge trigger. Observable previous trigger waveform (negative delay). Can freeze at any time waveform display (HOLD function). Comes 1Hz /3.3V square wave test signal source. 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.
