Please pay attention: Our options have oscilloscopes as well as oscilloscope probes.Please read it clearly before placing an order. You can't buy a mini oscilloscope for $8, my friend !!!Features and specifications:DSOPRO is a full function, high utility, high performance and cost-effective oscilloscope for the maintenance industry and the R&D industry. The oscilloscope has a real-time sampling rate of up to 20MS/s and a 5MHz analog bandwidth. With complete triggering function (single, normal, automatic), both the periodic analog signal and the aperiodic digital signal can be used freely. Large time base scanning mode can monitor slow level changes. Equipped with high efficiency one button AUTO, the measured waveform can be displayed without complicated adjustment. Display the High Definition LCD screen equipped with 2.4 inch 320*240 resolution. Extremely convenient and fast waveform storage function, built-in 16MB storage space, the maximum storage of 0 waveform pictures. Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions. Built in 1200mAh rechargeable lithium battery can be continuously charged for 3 hours at one time. Day mode and night mode can be changed according to their own preferences.:1:Memory compreion technology, waveform refresh screen does not flicker2:Afterglow display technology3:2.4 inch color display screen4:5MHz analog bandwidth @ 20MS/s sampling rate5:Fast waveform storage6:Built-in 16M storage space, the maximum storage of 0 waveform pictures7:Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions8:High measurement voltage range, 1X can measure 0 ~ 40 V, 10X can measure 40 ~ 800V9:Up to 11 s measurement:VPP,Vmax,Vmin,Vavg,Vrms,Frequent,Duty+,Duty-,Time+,Time-,Time10:At any time, the waveform display (pause function) is frozen11:Equipped with high efficiency one button AUTO12:Complete triggering function (single, normal, automatic)13:Built in 1200mAh rechargeable lithium battery can be continuously charged for 3 hours at one time14:Day mode and night mode15:Ultra small volume, easy to carrySpecifications:1:Analog band width: 5MHz2:Maximum real time sampling rate: 20MS/s3:Vertical sensitivity: mV/div ~ 200 V/div4:Horizontal time base range: S/div ~ 2nS/div5:Maximum input voltage: 40 V (1X probe), 800 V (10X probe)6:Storage depth: 40KB7:Input resistance: 1M8:ADC precision: 8bits9:Coupling mode: AC/DC10:Trigger mode: Single, Normal, Automatic11:Trigger edge: Ascending/descending edge12:External trigger voltage 0 – 40 V13:Display: 2.4 inch @ 320 * 24014:Power supply: 1200 mAh lithium battery15:Size: 107 x 70 x 24mm16:Weight: 1gPackage includes:1 x DSO PROoscilloscope host1 x Crocodile clip probe1 x Micro USB data line1 x User manual (English)
