New upgraded version: dual channel 2.8inch HD LCD oscilloscope with 500MSa/s real time sampling rate, 120MHz bandwidth, 500Khz signal generator frequency, vertical sensitivity range 10mV/-100V/, it uses ARM+FPGA+ADC chip combination for high speed signal acquisition and data processing, making it the perfect choice for various measurement and test fields Professional design: with three trigger modes (auto/normal/single), two trigger types (rise/fall) and two trigger levels (manual/auto). It offers 14 measurement and supports waveform parameter settings such as time base and amplitude. Save/preview waveforms by clicking the "Save" button, up to 1000 waveforms can be retained and unwanted waveforms can be deleted. One-click Auto Auto waveform adapts to the screen for accurate results without adjusting parameters Signal generator: The bottom of the oscilloscope can output a of waveforms with 2.5V amplitude, such as sine, square, triangle, half, singe, noise, etc. The frequency adjustment range of sine waveform is 0-10MHz, and the frequency range of other waveforms is 0-2MHz with an accuracy of up to 0.1Hz. For novices, it can also be used to assist in learning to use the oscilloscope and save the cost of buying expensive signal generators Cursor measurement: Support for manual cursor measurement Support for horizontal and vertical cursor measurement functions, useful for measuring pulsed signals, spikes or other non-periodic signals Safety in use: The handheld oscilloscope is intelligent and burn-proof, with a built-in high voltage protection module that can withstand up to 400V AC/ signals. And the built-in 4000mAh high quality battery can be used continuously for about 6 hours after a full charge Colour:Blue Material:Plastic Package Contents: 1 * Oscilloscope kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
