Accurate measurement Easy to use Built-in metal shielding ensures that the waveform is not disturbed Supports full-automatic mode and one-key automatic, and novices can quickly get startedBuilt-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 oscilloscopesSupports 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 cursorsFFT spect analysis FFT 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 FFT frequency measurement with cursorsPortable design, very suitable for field work or laboratory use, easy-to-use interface, suitable for beginners and experienced users Number of channels: 1Screen size: 2.8 inchesReal-time sampling rate: 250MSa/sAnalog bandwidth: 80MhzEquivalent sampling: 500MRise time: Less than 4nsMemory depth: 480Kbit (60Kpts)Time base range: 5ns -10sCoupling mode: AC/DCOne-key automatic: SupportWaveform measurement: 14 typesDC offset: 3%High-precision frequency meter: 10Hz-30MhzWaveform graph saving: SupportFrequency accuracy: 0.01%Pulse counter: SupportFFT: SupportSignal source waveform: sine/square/triangle wave, etc.Signal generator: 3VVoltage and frequency 1Hz-1MHzThe product appearance and printed words may vary depending on the batch, but this does not affect useColour:Bla
