Accurate measurement Easy to use Builtin metal shielding ensures that the waveform is not Supports fullautomatic mode and onekey automatic, and novices can quickly get startedBuiltin 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 02Mhz 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 cursors spectrum analysis is a fast algorithm that converts time domain waveforms to frequency domain, which can extract frequency components in the time domain waveform. This machine uses the base4 butterfly algorithm, which is faster than the traditional base2, has high resolution and does not affect the normal waveform refresh, and supports frequency measurement with cursorsPortable design, very suitable for field work or laboratory use, easytouse interface, suitable for beginners and experienced usersNumber of channels: 1Screen size: 2.8 inchesRealtime sampling rate: 250MSa/sAnalog bandwidth: 80MhzEquivalent sampling: 500MRise time: Less than 4nsMemory depth: 480Kbit (60Kpts)Time base range: 5ns 10sCoupling mode: AC/DCOnekey automatic: SupportWaveform measurement: 14 typesDC offset: 3%Highprecision frequency meter: 10Hz30MhzWaveform graph saving: SupportFrequency accuracy: 0.01%Pulse counter: Support: SupportSignal source waveform: sine/square/triangle wave, etc.Signal generator: 3VVoltage and frequency 1Hz1MHzThe product appearance and printed words depending on the batch, but this does not affect useColour:BlackMaterial:ABSPackage Contents:1 x Main Unit1 x Probe1 x Data CableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
