“With the high density of chip design and the continuous increase of unit computing power, chip design with high power consumption, high current, high speed and small size requires the stability of power supply voltage, the dependence of low impedance power supply path and power supply noise margin. have put forward higher requirements. Power Integrity (PI) and Signal Integrity (SI) affect each other. If the signal quality is not good, the high probability that the power supply is not good, the power quality is not good, the signal quality is definitely not good.
Easy “driving” without mistakes
Foreword: I am Xiaotai. Xiaotai can test thousands of Electronic devices a year, but he still has time to go on a trip. How did he do it? The intelligent identification information of the Ethernet can quickly pass through the security check; with the help of the USB2.0 fast lane, you can arrive at the terminal in time, buy a cup of coffee, and just wait for boarding; DDR3 flights can shorten the journey time by one-third and reach the destination faster ; Small air turbulence was detected in real time during the flight, and the flight posture was adjusted in time with the help of electronic equipment, Xiaotai was completely unaffected; brought the newly purchased noise-cancelling headphones to listen to music, and enjoy a safe and comfortable trip; when you got off the plane, the phone called and told us The smart car is already in place, and the Spectrum View software restores the invisible waveform to the original signal, so that the call is clear and smooth, and the car is picked up smoothly; the intelligent driverless car makes the journey to the scenic spot easier, one-click start, cool big screen Display real-time road conditions, easy and worry-free, and have a good mood all the way; as a technology hipster, photo punching is indispensable, using the smart phone designed with MIPI bus function, the restored various beautiful scenery is worth a circle of friends; ensure the necessary electronic equipment during the journey is always Online, stable power support is essential.
These 9 travel scenarios, Xiaotai can easily test them.
Who is Xiaotai? Xiaotai is a Tektronix MSO6B oscilloscope with up to 10G bandwidth, 50G sampling rate, and eight channels, helping engineers complete tasks in time and travel as they please. 【Oscilloscope Travel Guide | How can an engineer start a trip that says go? ]Reveals the three elements of comfortable travel, this article is the third article “Easy “driving” without mistakes.
Make sure the essential electronic devices on the go are always online, and stable power support is essential!
Provide a reliable power supply environment for your circuit In electronic circuits, the power supply is equivalent to the heart of active devices, providing energy to the components continuously. The quality of the power supply directly affects the performance of the components. The design, manufacture and quality management of the power supply require sophisticated electronic equipment to simulate the various characteristics (that is, various specifications) of the power supply during actual operation, and can only be put into use after the verification is passed. A clean power supply is the premise for the stable operation of digital circuits. Ripple and noise of the power supply will affect the quality of the power supply.
With the high density of chip design and the continuous increase of unit computing power, chip design with high power consumption, high current, high speed and small size requires the stability of power supply voltage, the dependence of low impedance power supply path and power supply noise margin. have put forward higher requirements. Power Integrity (PI) and Signal Integrity (SI) affect each other. If the signal quality is not good, the high probability that the power supply is not good, the power quality is not good, the signal quality is definitely not good.
Tektronix MSO6B oscilloscope pays special attention to the design of low-noise power supply, and has carried out a large number of analysis including spectrum analysis on the power supply signal, and has carried out detailed frequency domain analysis of different spurious signals, and then focused on solving these problems, providing a circuit for the circuit. Reliable power supply environment.
Ensuring the performance and compliance of next-generation automotive Ethernet makes the journey to attractions easy!
The Automotive Ethernet concept is an Ethernet physical layer standard designed for automotive networking applications such as advanced safety functions, comfort and infotainment functions. This technology reduces networking costs and cable weight while increasing signal bandwidth. To achieve higher signal bandwidth, automotive Ethernet uses a full-duplex communication link over twisted-pair cables, supporting simultaneous transceiver functions and PAM3 signaling. Full duplex communication with PAM3 can complicate viewing of automotive Ethernet traffic and signal integrity testing.
Engineers often face the following test challenges when developing and designing automotive electronic circuits that include automotive Ethernet:
• How to test and analyze automotive Ethernet signal quality
• How to parse automotive Ethernet transmission data
• How to analyze and debug various automotive bus electronic circuits including automotive Ethernet
Tektronix oscilloscopes power automotive connected applications such as advanced safety features, comfort and infotainment. The signal separation solution provides a more accurate view of the real signal than the directional coupler signal method, simplifies component-level and system-level test setup, reduces test time, and meets automotive lifecycle testing needs.
