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 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 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 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 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 Number of channels: 1 Screen size: 2.8 inches Real-time sampling rate: 250MSa/s Analog bandwidth: 80Mhz Equivalent sampling: 500M Rise time: Less than 4ns Memory depth: 480Kbit (60Kpts) Time base range: 5ns -10s Coupling mode: AC/DC One-key automatic: Support Waveform measurement: 14 types DC offset: 3% High-precision frequency meter: 10Hz-30Mhz Waveform graph saving: Support Frequency accuracy: 0.01% Pulse counter: Support : Support Signal source waveform: sine/square/triangle wave, etc. Signal generator: 3V Voltage and frequency 1Hz-1MHz The product appearance and printed words depending on the batch, but this does not affect use Colour:Black Material:ABS Package Contents: 1 x Main Unit 1 x Probe 1 x Data Cable Only 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. The measurement allowed error is +/- 1-3cm.
