Those who are familiar with oscilloscopes may have had this confusion: there are two types of input impedance: 1MΩ and 50Ω. How should we choose? 1. Transmission line To explain the origin of 50Ω, we need to first...
In order to be the best, people will go to unimaginable lengths. For example, athletes train tirelessly just to be a millisecond ahead in a competition. Students spend years studying....
ARM's R&D journey is long and interesting. The well-known advantages of development and the helplessness when faced with problems make people love and hate ARM. What is your relationship with ARM?...
Winter is coming! The damage caused by static electricity to electronic components and equipment cannot be ignored in winter. Why do production lines invest so much in anti-static measures? Because they are afraid of static electricity!...
When designing a circuit, many engineers will not forget to add various protection circuits, especially on the particularly fragile IO ports. Maybe you have not paid attention to "high voltage pulses" before, today here is a tip for you...
With the completion of the 630 and 930 photovoltaic projects, outdoor testing of photovoltaic inverters has become more and more common. How can we quickly and effectively test the efficiency of inverters? How can we find a suitable testing tool? Here we will help you find...
Power modules have been widely used in industrial communications, medical, power and other fields due to their modular design and high reliability....
The encryption and decryption of embedded system products are always a contradictory unity. In order to protect the technical achievements of product developers, it is very necessary to study new encryption technologies....
There are three major members in the CAN-bus family, namely high-speed CAN, fault-tolerant CAN, and single-wire CAN. Among them, fault-tolerant CAN is also called low-speed CAN. What are the similarities and differences between it and the most commonly used high-speed CAN? Here we will share with you...
What do power engineers fear the most? Machine crashes! The MOS tubes break down for no apparent reason. They are really afraid and hate it. But what exactly went wrong? All of this is related to SOA....
Nowadays, electric vehicle models are changing with each passing day. How can we stand out from the crowd? A powerful electric vehicle must have a high-quality battery management system (BMS)....
The goal of building 4.5 million charging piles nationwide by 2020 is one year away, but the number of public charging piles is still less than 250,000 and the utilization rate is low, with the problem of pile communication failure being particularly prominent....
Local error and global notification are typical types of CAN bus errors. How to quickly locate the cause of the error through error messages and waveforms? This article briefly analyzes the error based on field test cases....
Su Shi said in "Red Cliff Fu" that "the breeze on the river and the bright moon in the mountains are heard by the ears and become what the eyes see". The ears and eyes are the collection instruments for humans to obtain "the beautiful scenery of the world", and in product research...
Current probes are essential accessories for oscilloscopes to measure current, but prices vary greatly between brands. What kind of current probe is reliable? Here are some tips for verifying the reliability of current probes....
