◆ Digital oscilloscopes of several major brands
● Tektronix digital oscilloscope
Tektronix TDS 1000B digital oscilloscope is a digital oscilloscope introduced by Tektronix Technology Co., Ltd., with a bandwidth as high as 100 MHz and a sampling rate as high as 1 GS/s, which is light in design and economical in function. The portable standard functions of TDS 1000B series digital oscilloscopes include USB connection capability, 12 automatic measurement and simple user interface.
Low Ding Yang technology digital oscilloscope.
SIGLENT is the world's largest manufacturer of digital oscilloscopes ODM, and also the largest manufacturer of oscilloscopes in China.
International R&D concept, to create a more powerful and humanized SDS 1000CFL series! This product inherits the multifunction and high performance of Ding Yang products, and provides up to four channels and an external trigger input channel, which can simultaneously collect and display multi-channel signals, meeting the application requirements of product development and verification. At the same time, the product is equipped with a sampling rate as high as 2GSa/S and a 7-inch color TFT LCD screen, which meets the test requirements of higher bandwidth and higher sampling rate in complex hardware design. The storage depth of single channel 24K is ahead of domestic similar products, and the signal observation time is longer and the signal details are understood more deeply. Powerful trigger and analysis capabilities make it very easy to capture and analyze waveforms, which greatly improves the testing efficiency. Rich interface configuration realizes seamless connection with PC, meets the requirements of waveform data processing, and quickly builds a test system.
● Fluke digital oscilloscope
FLUKE5500A is a high-performance multifunctional calibrator of FLUKE Company in the United States, which can calibrate various instruments such as hand-held and desktop multimeters, oscilloscopes, power meters, electronic thermometers, data collectors, power harmonic analyzers, process calibrators, etc. FLUKE5500A provides three standard interfaces: GPIB(IEEE-488), RS-232 and 5725A. In terms of security, it meets IEC/KOOC-0/0/0-/KOOC-0/(/KOOC-0/992-/KOOC-0/), ANSI/ISA-S82.0/KOOC-0/-/KOOC-0/994 and CAN/. Kloc-0/00V and current up to 165438 can provide various waveforms and harmonics of DC voltage and current, and output two voltages or one voltage and one current at the same time, simulating power, resistance, capacitive thermocouple and RTD. Its oscilloscope calibrator also provides stable amplitude sine wave, fast edge, time stamp and amplitude signal.
◆ Advantages of digital oscilloscope
1. Small size, light weight, easy to carry, LCD display.
2. Waveforms can be stored for a long time, and the stored waveforms can be amplified and analyzed.
3. It is especially suitable for measuring single-shot and low-frequency signals, and there is no flicker phenomenon of analog oscilloscope when measuring low-frequency signals.
4. There are more trigger modes, besides the pre-trigger that analog oscilloscope does not have, there are also logic trigger and pulse width trigger.
5. Computers, printers and plotters can be connected through GPIB, RS232 and USB interfaces, and files can be printed, archived and analyzed.
6. Strong waveform processing ability, which can automatically measure frequency, rise time, pulse width and other parameters.
