This is a kind of quality oscilloscope, with 120M bandwidth and 500M sampling rate, more stable and with higher precisions. 14 measurement options available, Frequency, Peaks-to-Peaks, Duty cycle, Amplitude, RMS, Average, Period, +Pulse width, -Pulse width, Max, Min,Top, Base, -Duty cycle. Support switch the output waveform: sinewave, squarewave, trianglewave, etc. Widely application on mcu debugging, car repair, home appliance repair, DIY electronic competition, power-supply debugging, inverter, etc. You can have a try. Features: Resolution: Equipped with 320*240 resolution color display, with bright colors and high contrast, you can see the data clearly. Bandwidth and sampling rate: With 120M bandwidth and 500M sampling rate, more stable and with higher precisions. High bandwidth: Up to 120M bandwidth can easily cope with measurement tests in various fields. There are 14 measurement options available as follows:Frequency, Peaks-to-Peaks, Duty cycle, Amplitude, RMS, Average, Period, +Pulse width, -Pulse width, Max, Min,Top, Base, -Duty cycle. Support switch the output waveform: sinewave, squarewave, trianglewave, etc. FFT: FFT is used to convert time domain waveforms into frequency domain and is widely used in harmonic analysis and other fields. Support three display modes: logarithmic, linear, and musicspectrum. Reference waveform: you can measure the waveform first, lock the current waveform on the screen, and the normally refreshed waveform will not be affected. Reference waveforms are useful for single-channel oscilloscopes. With reference waveforms, you can easily compare the waveforms of two channels. Complete trigger: Trig mode: Auto/Normal; Trigger types: Rise/Fall, Trigger level: Manual/Auto Vertical sensitivity and time base: The scope's vertical sensitivity is ranges from 10mV/div to 10V/div (1X ranges). The oscilloscope time base is ranges from 5ns to 10s. Waveform save: One-click to save the screen waveform, and also support delete or browse historical screenshots.. Connect to PC: The screenshot pictures can be exported to a computers via a USB connection. Video output:The 3.5mm headphone jack at the bottom can output AV video simulating signal, which can be connected to a TV or projector. Power-supply: built-in rechargeable lithium battery, 3.7V, 3000mAh large capacity, full-charged can provides long working time. Compact size: lightweight and portable, also can be used as a portable tool for on-site debugging. Widely applications: suitable for mcu debugging, car repair, home appliance repair, DIY electronic competition, power-supply debugging, inverter, etc. Specicifations: Name: Oscilloscope Model: DSO1511G Color: yellow, green (optional) Battery: 1 * 2.5V, 3000mAh battery (included) Channels: 1 Screen size: 2.4 inch Measurement: 14 types Resolution: 320*240 Bandwidth: 120M Sampling rate: 500M Rise time:
