Equipped with 320*240 resolution color TFT LCD display, with bright colors and high contrast, you can see the data clearly. ARM+FPGA+ADC architecture, 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 fields. Squarewave generator: The upperside of the oscilloscope can output an adjustable squarewave of 3V amplitude, the frequency-adjustment-range is 0-2MHz, the accuracy is up to 0.1Hz. The duty cycle-adjustment-range is 1%-99%. It can be used to calibrate new probes, drive mosFETs, replace crystals, etc. : 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 music spectrum. Reference waveform: Lock the current waveform on the screen, and the normally refreshed waveform 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/Single; Trigger types: Rise/Fall, Trigger level: Manual/Auto. Waveform save/view: One-click to save the screen waveform, enter the waveform preview page, click the thumbnail to observe the full screen, and up to 250 waveforms piecture can be saved. Unwanted waveforms can be deleted. Export picture to computer: through the USB cable connection, the user-stored waveforms can be exported to the computer(up to 50 at a time). You can copy it to a computer and use it for the paper material, or send it to others for analysis to find and analyze problems. Detailed analysis: After stopping, you can move the waveform left and right to find the place youare interested in and expand (adjust the timebase) to observe the details and analyze the se of the problem. Power-supply: built-in rechargeable lithium battery, 3.7V, 3000mAh large caparity, full- can provides long working time. Compact size: 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. Name:Oscilloscope Model:DS01511 Hardware solution: ARM+FPGA+ADC Battery: 1 x built-in rechargeable lithium battery, 3.7V, 2500mAh (included) Screen: 2.4 inch TFT LCD Channel: 1 Resolution: 320*240 Bandwidth: 120MHz Sampling rate: 500M Rise time: Less than 3ns Storage depth: 128Kbit Impedance: 1M Time base: 5ns-10s Vertical sensitivity: 10mV/-10V/ Max voltage: 40V(x1);400V(x10) Trigger mode: Auto/Normal/Single Trigger type: rise/fall Display mode: YT/Roll Persistence: None/1s/ Coupling: Waveform measurement: 14 types Precisions of measurement: 2% Reference waveform: support Squarewave generator: support Screenshot: support USB picture export: support Waveout: support Frequency: 0.01% : support Language: CN/EN Charge:micUSB 5V, 700mA Item size:73x93x32mm / 2.87x3.66x1.26in Color:Cyan Material:ABS Package Contents: 1 * Digital Oscilloscope 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.
