ดิจิตอลออสซิลโลสโคป ออสซิลโลสโคปแบบพวกพา Pocket Digital Oscilloscope 4CH  DSO203 ข้อมูลของสินค้า: This pocket oscilloscope is primarily used for applications in the following situations: 1. Repair common electronic equipment? outside (Air conditioning or Industrial frequency inverter power supply, AC / DC switching power supply or inverter, elevator and building fire safety equipment, industrial control circuit) 2. Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other communications interface circuits, LED display and keyboard scan driver circuit, brushless motor drive circuit 3. Audio equipment and circuits, electronic toys and remote control models, car repair electronic circuits 4. School after-school teaching practice and student development of electronic small production 5. Need to slow signal changes observed applications (such as: relay and switch contacts jitter, battery charge and discharge curves of the load transient response power supply, temperature sensor features measurement) 6. The related supply t electronic circuit (SCR voltage regulator, power factor correction, electronic energy saving lamps, dysprosium lamp mercury lamp sodium lamp xenon lights drive circuit), As for other issues such as: CPU clock, RAM access, bus and USB or Ethernet signal measurement, high frequency and the video circuitry and the need to use FFT for signal analysis and so on occasion, The oscilloscope valued less than $1000 are not necessarily qualified for these. We advice to buy high-end oscilloscope! Deserves special mention is this pocket-sized internal battery-powered oscilloscope can be used, so in the field measurement, Ground is completely suspended, can be completely the same as multimeters, which measure what point, do not consider the issue of ground isolation. DSO203 is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32VCT6), providing 72MS/s sampling rate with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform, user application and upgrade firmware. Feature 1) 2 probe connectors 2) 4 inputs & 4 tracks (2 analog 2 digital) 3) A custom waveform output (including the built-in sine, square, triangle) 4) Built-in 2M USB disk 5) Very low power consumptionSpecification Analog channel * 2 [CH_A] [CH_B] Digital channel * 2 [CH_C] [CH_D] Vertical Scale 20mV-10V/div (1-2-5 step) on x1 probe / 200mV -100V/div (1-2-5 step) on x10 probe Vertical resolution 8 bit Input coupling AC/DC Max input voltage 80Vpp (x1 probe) / 400Vpp (x10 probe) Storage 4K per channel / 8K on single channel Software trigger type edge, pulse, level (to be added) Hardware trigger type edge Trigger source CH1/CH2/EXT Trigger mode Auto, Normal, Single, SCAN, None Test Signal generater 10Hz to 8Mhz 2.8Vpp Square Wave, duty circle 10~90% adjustable / 10Hz to 20Khz 2.8Vpp Sin, Square, Saw, Triangle wave Storage internal 2MB USB disk, BMP, DAT file Auto measure Vmax, Vmin, Vpp, Vavr, Vrms, Freq, Period, Pulse, Duty Cursor measurement Level, Voltage Display mode CH1, CH2, EXT, CH1+CH2, CH1-CH2, CH1*CH2 Sampling mode real time Sampling rate 30S/s - 72MS/s Power Lipo battery Dimension 98 * 60 * 14.5 (mm) Weight 80g (without battery) Accessories within Pack 2 mcx osilloscope probe Cautions The warnings and wrong operations possible cause dangerous. Description 3" 240 ? 400 widescreen color TFT LCD screen, STM32 is the master MCU, with the FPGA to implement the control and management of external ADC and data cache. At the same time to reduce the size and easy to DIY manual welding, MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package. 36M+36M sampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72M. FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve. The AD9288-40 Overclocking to achieve 72M+72M sampling frequency, so that the maximum single-channel sampling rate up to 144M. Analog channel circuit using unity gain> 150MHz op amp, so the actual 30MHz analog bandwidth is expected to do more. As low power, low-cost, QFP package and other conditions of the FPGA, storage capacity is not large, so DSO203 sampling depth of the current situation for the multi-channel 4096 points per channel, single-channel work cases, 8192 points. ***รับประกันสินค้า 6 เดือน
