The FNIRSI-1013D is a dual-channel oscilloscope designed for R&D and maintenance, offering a 1GSa/s real-time sampling rate and 100MHz bandwidth per channel. It supports various trigger modes (single/normal/auto) and can handle up to 400V with built-in high-voltage protection. The 7-inch 800x480 touchscreen provides easy control with one-key AUTO function for quick waveform display. It includes convenient features like cursor measurements, peak detection, and built-in 1GB storage for up to 1000 screenshots and waveforms. The oscilloscope also supports USB connectivity for data sharing, and its 6000mAh battery lasts up to 4 hours on a single charge, usable even while charging.   Highlights: Professional Designed: FNIRSI oscilloscope has a real-time sampling rate of up to 1GSA/S and an analog bandwidth of 100MHZ * 2. Fnirsi oscilloscope has a complete trigger function (single/normal/automatic), it can be used freely for both periodic analog signals and aperiodic digital signals. Highly Performance: 7 inches, 800 * 480 resolution, bright colors and high contrast. Ultra-thin and easy to carry. Built-in high-voltage protection module,can tolerate a continuous voltage of up to 400V. 6000mAh high-performance lithium battery, can be used continuously for 4 hours after fully charged. Easy to Operate: Equipped with efficient one-button automatic device. One-click waveform saving and screenshots. The built-in 1GB storage space can store up to 1000 screenshots 1000 sets of waveform data.Powerful waveform picture manager supports thumbnail browsing, viewing, detailed viewing, page turning, deletion and waveform zooming in, zooming out, moving, etc Easily Measuring : Capacitive screen touch & gesture operation, cursor measurement function, when manually reading amplitude-frequency parameters, you do not need to read the background scale unit and quantity, and you can directly get the peak-to-peak value and frequency without conversion. Lissajous Graphic Display & FFT Viewing: Lissajous graphic display function can be used to compare the amplitude, frequency and phase of the two sets of signals. FFT viewing function can roughly estimation of the harmonic content of the signal.   Features 2 Channels Portable Handheld Tablet Oscilloscope 1GSa/s Sampling Rate (1X=5MHz,10X=100MHz)  100MHZ * 2analog bandwidth 7" TFT LCD Touch Screen Complete trigger function (single/normal/automatic).
