Training for electronic production, complete detailed descriptive information, including schemas, production guides, instructions, problem-solving methods, etc., make for a high success rate. of component species for students to identify elements, inline elements welding, SMD soldering component training. The kit uses an ARM -M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display that can be used as a test arm development board. Available resources, partner capabilities can be a secondary development kit based on, for example, it can be converted to Millivoltmeter, data, and so on. The circuit is simple, reliable, value for money. Power input: DC 9V (power adapter not included) Maximum real -time sampling rate: 1Msps Accuracy: 12Bit Sampling buffer depth: 1024 bytes Analog bandwidth: 0 -200KHz Vertical sensitivity: 10mV/ -5V/ (1-2-5 way) Adjustable vertical displacement, and with instructions Input Impedance: 1M Maximum input voltage: 50Vpp (1: 1 probe), 400Vpp (10: 1 probe) Coupling modes include DC/AC/GND Horizontal time base range: 10 s/-50s/ (1-2-5 mode) With automatic, normal -shot modes, it's easy to capture time waveforms There is an increase or a fall edge trigger Adjustable trigger level position, and with instructions Trigger waveform due to previous (negative delay) Can freeze at any time waveform display (holding function) Comes 1Hz /3.3V square wave source Colour: red Material: PC+metal Package Contents: 1 * Soldered 2.4 Inch TFT Digital Oscilloscope Only the above package content, other products are not included. Note: Light 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.
