Electrical and electronic

Among the devices used for electronic measurement, the oscilloscope is one of the devices that helps us see directly how the electrical signal is happening. Each waveform displayed on the screen is the “language” of the circuit. Understanding the waveform will help us know whether the circuit is healthy or having problems.

In the context of the global move towards energy saving and CO₂ emission reduction, LED technology is dominating. From consumer devices such as TVs, phones, flashlights to residential, industrial, streetlights or office lighting systems, LED has become a popular alternative to incandescent lamps.

In the second half of 2025, the test and measurement market has seen a clear shift from traditional swept spectrum analysis to real-time spectrum analysis. As RF signals become shorter, more complex, and increasingly dense, engineers are turning to tools capable of capturing every variation within just a few microseconds. In this context, Rigol recently introduced the RSA6000 series, a new-generation real-time spectrum analyzer line that marks a significant step forward for the company in the high-end equipment segment.

In the fields of engineering, design and manufacturing, color accuracy is a factor that directly affects the quality and stability of the product. To control and evaluate color objectively, professionals often use the L*a*b* color system, a neutral measurement standard widely applied to many types of materials.

Fluke iSee™ TC01C is a new model in the thermal camera line for smartphones, launched in September. Developed by Fluke with the ability to measure temperature accurately in an ultra-compact design. The device uses a Type C port that is directly compatible with iPhone and iPad, providing a fast, flexible and convenient measurement experience for professional users.

Fluke iSee™ TC01A/TC01B is a family of thermal cameras for smartphones from Fluke, developed to provide accurate temperature measurements in a compact, lightweight design.

In a convenience store or supermarket, the payment method is a decisive factor in the customer experience. Employees cannot manually enter each product code like in the old days because it is easy to make mistakes, wasting time and causing congestion at the cashier counter. Handheld barcode scanners solve this problem by allowing each item to be quickly scanned in a split second. Best of all, the data is fed directly into the sales system, eliminating the situation of entering wrong prices or missing items.

When implementing a transmitting and receiving system, the first question that engineers have to solve is: how to prevent the high-power signal from the transmitter from bouncing back and damaging the receiver, while both have to use the same antenna? At first glance, many people think that they can install two separate antennas or use a switch. In fact, the cost, latency and complexity will increase a lot. This is the reason why the signal transmitter is used, because it solves both technical and economic problems.

Light meters (lux meters) are familiar tools in many industries: photography, construction, and work environment control. However, many users encounter problems when the battery runs out quickly or suddenly runs out, causing work interruptions. This is a fairly common situation, and is also the reason why many people often look for tips to optimize battery life.
