Tips: lt is normal to find scratches on the screen after receivingthe product.Just tear off the surface film.(The panel cannot be avoided in the production process,So there is a layer of protective film to protect the panel) Product Feature: The is a versatile, highly practical, cost-effective handheld oscilloscope for the maintenance industry and the R&D industry with s real-time sampling rate of up to 500MS/s and 100MHz analog bandwidth.With full trigger function (single, normal, automatic), it can be used freely for both periodic analog signals and non-periodic digital signals. The built-in high voltage protection module can withstand up to 400V continuous voltage and 600V peak voltage. There is no need to worry about the oscilloscope burnout caused by the high voltage not being probed to the 10X position.Large time base scan mode that monitors slow level changes. Equipped with high-efficiency one-button AUTO, the measured waveform can be displayed without complicated adjustment. Extremely convenient and fast waveform storage function, built-in 64M storage space, can store up to 2000 waveform pictures, the storage process is simple and fast, save the current waveform anytime and anywhere Powerful waveform file manager, support for thumbnail browsing, viewing, detail viewing, page turning, deletion and more Product Specifications: Maximum real time sampling rate: 500MS/s Vertical sensitivity: 50 mV/div ~ 100 V/div Horizontal time base range: 50S/div ~ 6nS/div Maximum test voltage: 80 V (1X probe), 800 V (10X probe) Storage depth: 128KB ADC precision: 8bits Coupling mode: AC/DC Trigger edge: Ascending/descending edge External trigger voltage 0 80 V Display: 2.4 inch - 320*240 - IPS process Power supply: 5000 mAh lithium battery Size: 114mm x 74mm x 33mm Weight: 300g Package Lists: 1 x Oscilloscope Host 1 x Matching 100MHz Probe(1X and 10X) 1 x Micro USB Data Line 1 x User Manual Before you place an order, please provide me with English information to facilitate our delivery and logistics
