The oscilloscope has up to 20 ms / s real-time sampling rate and an analog bandwidth of 5 MHz. Equipped with the high efficiency an automatic knob, the measured waveform can be displayed without complicated adjustment. 2.4 inch color screen, 320 * 240 resolution, displays data clearly for easy reading.Day mode and night mode can be changed according to your own preferences. Built in 1500mAh rechargeable lithium battery can be continuously charged for 3 hours at a time. Memory compression technology, waveform refresh screen not flicker.Extremely convenient and fast waveform storage function. Built-in storage space of 16m, maximum storage of 500 waveform images.Powerful waveform file manager, support for thumbnail browsing, visualization, detail viewing, flip, delete and other functions.High measurement voltage range, 1x can measure 0 40 40 v, 10x can measure 40 800 v. Up to 11 measurement parameters: vpp, vmax, vmin, vavg, vrms, frequent, must +, must-, time +, time-, time. At any time, the waveform display (pause function) is frozen. Full function (single, normal, auto).The oscilloscope is a complete function, high utility, high performance and cost effective handheld oscilloscope for the maintenance industry and the industry. With full trigger function (single, normal, auto), both periodic analog signal and dic odic digital signal can be used freely. Large time base scan mode can monitor slow level changes.Specifications:Analog Bandwidth: 5 mhzMaximum Real Time Sampling Rate: 20 ms / sVertical Sensitivity: 50mV / div ~ 200 V / divhorizontal time base range: 50 s / div 250250ns / divMaximum Input Voltage: 40 V (probe 1x), 800 V (probe 10x)storing depth: 40KBResistance input: 1 mAdc accuracy: 8 bitsCoupling mode: Trigger mode: single, normal, automaticTrigger edge: rising / falling edge Triggerexternal voltage: 0-40 vDisplay: 2.4 inch @ 320 * 240Source power supply: 3.7 v, 1500 mAh lithium batteryOscilloscope bandwidth: 80 mhzOscillosprobe max. input voltage: 600 v (dc + acp-p)Oscilloscope input resistance: 10mOscilloscope host size: 107 * 70 * 24mmColor: WhiteMaterial: metalSize: 16*10*9.5cmPackage Contents:1 * ADS2050H Oscilloscope Host1 * Clip Probe1 * -USB Data Line1 * P6100 Oscilloscope Probe1 * User Manual (English)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
