DS211 Digital Storage Portable Oscilloscope Handheld 1MSa/s Built-in Battery

  

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). 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.

Overhaul of audio equipment and circuits, electronic toys and remote control models, and automotive electronic circuits. School teaching practice and students' extracurricular development of electronic mini-productions. 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). 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 Ethernet signal measurement, high-frequency and video circuits, and signal analysis that requires FFT, this oscilloscope is not competent. It is especially worth mentioning that this pocket oscilloscope can be powered by an internal battery, so when measuring on-site, the ground wire is completely suspended, which can be completely like a multimeter, which point to measure, without considering the problem of ground isolation. Number of channels: 1 analog channel + 1 internal channel. Horizontal scanning speed: 1uS/Div2S/Div (1-2-5 step). Vertical sensitivity: 20mv/Div10V/Div (1-2-5 step).

Trigger Mode: Rising/Falling Edge Trigger. Computational waveforms: -A, RecA, A+ RecA. Signal output: square wave, sine wave, triangle wave, sawtooth wave.

Trigger Mode: Auto, Normal, Single, None, Scan. Storage: 8MB built-in U disk. Number of apps that can be installed: 1. Screen size: 2.8 inches. Host size: 106.5mmX55.7mmX11.5mm.
