Supports cursor measurement, and the cursor can be moved manually to measure the time between the left and right cursors and the voltage between the upper and lower cursors Built-in signal generator function, which can output multiple waveforms such as sine wave, square wave, triangle wave, etc., with a fixed amplitude of 3V and a frequency of 0-2Mhz accurately adjustable. It can be used for probe calibration, DIY circuit op amp debugging, and auxiliary learning of oscilloscopes Accurate measurement Easy to use Built-in metal shielding ensures that the waveform is not Supports full-automatic mode and one-key automatic, and novices can quickly get started spectrum analysis is a fast algorithm that converts time domain waveforms to frequency domain, which can extract various frequency components in the time domain waveform. This machine uses the base-4 butterfly algorithm, which is faster than the traditional base-2, has high resolution and does not affect the normal waveform refresh, and supports frequency measurement with cursors Portable design, very suitable for field work or laboratory use, easy-to-use interface, suitable for beginners and experienced users, Manufacturer: Ounfhtrttk
