Предлагам Ви нов, неразличим от нов, цифров осцилоскоп ZEEWEII 18MHz с батерия и дълга работна продължителност. Това е масов, популярен модел, който се е наложил вече за последните няколко години като прост, надежден, с добре направени менюта. Има и сигнален (функционен) генератор. По-долу пускам спецификацията от производителя. Продавам го, защото взех няколко, но избрах двуканален.

Features:
Equipped with 320*240 resolution color TFT LCD display, with bright colors and high contrast, you can see the data clearly.
ARM+FPGA+ADC architecture, with 18M bandwidth and 40M sampling rate, more stable and with higher precisions.
High bandwidth: Up to 18M bandwidth can easily cope with measurement tests in various fields.
singnal generator: The upperside of the oscilloscope can output an adjustable waveform of 3V amplitude, the frequency-adjustment-range is 0-1MHz. The duty cycle-adjustment-range is 1%-99%. It can be used to calibrate new probes, drive mosFETs, replace crystals, etc.
Complete trigger: Trig mode: Auto/Normal/Single; Trigger types: Rise/Fall, Trigger level: Manual/Auto
Detailed analysis: After stopping, you can move the waveform left and right to find the place youare interested in and expand (adjust the timebase) to observe the details and analyze the cause of the problem.
Power-supply: built-in rechargeable lithium battery, 3.7V, 1000mAh large caparity, full-charged can provides long working time.
Compact size: lightweight and portable, also can be used as a portable tool for on-site debugging.
Widely applications: suitable for mcu debugging, car repair, home appliance repair, DIY electronic competition, power-supply debugging, inverter, etc.
