Features:4CH oscilloscope function/arbitrary waveform generator.The performance of this model could be even better than the performance of benchtop oscilloscope. It has 4 independent analog channels, 1GSa/s real-time sampling rate, 2mV??10V/DIV input sensitivity, and 70MHz/100MHz/200MHz/250MHz bandwidth.Pass/fail test, resourceful trigger function, dynamic cursor tracking, waveform record and replay function. The operation interface is similar to banchtop oscilloscope, easy to operate with high cost performance.USB2.0 Interface, plug and play device.Good mechanical design with small size which is easy for carrying. The outer case is made by the same material with iPad - Anodised aluminium. It has great heat resistance and abrasive resistance with beautiful appearance. The hardness of aluminium alloy surface is greatly improved.Fit for the portable computers, table PC, and repairing/fixing of production line. Suitable for business trip use.Software support: Windows10, Windows 8, Windows 7.The waveform data could be output to EXCEL,BMP,JPG as time and voltage category.More than 20 kinds of automatic measurement function, PASS/FAIL Check function, fit for engineering application.Waveform averaging, afterglow, lightness control, reverse, add, subtract, multiply, divide, X-Y display.FFT spectrum analyzer.One computer could connect with multiple oscilloscopes, expand the channel number easily.USBXI standard interface, easy to insert into USBXI case to constitute assembling instrument.Provide secondary development library DLL; Provide LabviewVBVCQT developing examples.
