DS211 2.8 Inch Portable Digital Oscilloscope Professional 200KHz Bandwidth Single channel Oscilloscope Signal Generator 320*240

Features:

1. On-site maintenance of ordinary electronic equipment (inverter air conditioner or industrial inverter power supply, AC/DC switching power supply or inverter, elevator and building fire protection equipment, industrial field control circuit)

2. Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other communication interface circuits, LED display and keyboard scanning drive circuits, brushless motor drive circuits

3. Overhaul of audio equipment and circuits, electronic toys and remote control models, and automotive electronic circuits

4. School teaching practice and students' extracurricular development of electronic mini-productions

5. Applications that need to observe slow signal changes (such as: relay and switch contact jitter, battery charge-discharge curve, regulated power supply load transient response, temperature sensor characteristic measurement)

6. Electronic circuits related to power supply (thyristor voltage regulation, power factor compensation, electronic energy-saving lamps, sodium lamps, dysprosium lamps, mercury lamps, xenon lamps and other street lamp drive circuits), as for others such as: CPU clock, RAM access, bus and USB or This oscilloscope is incompetent for Ethernet signal measurement, high frequency and video circuits, and signal analysis that requires FFT. It is especially worth mentioning that this pocket oscilloscope can be powered by an internal battery, so during field measurements , the ground wire is completely suspended, which can be completely like a multimeter, which point to measure, without considering the problem of ground isolation
