What is the SPC port on an electronic depth gauge used for?
2026年05月20日 10時18分49秒

When looking at the specifications of an electronic depth gauge, most people immediately notice the smallest division, the measuring range, or the water resistance. However, on the side of many models, there is an additional small port marked SPC

Why Products Still Failure Even After Passing Temperature and Humidity Aging Tests?
2026年05月19日 16時53分26秒

Some devices successfully complete full environmental test cycles, yet still develop corrosion, leakage current, or stability issues only a few months after being deployed in real-world conditions. In reliability testing and material durability evaluation, Temperature and Humidity Test Chamber systems are commonly used to simulate years of operation within just days or weeks. High temperature combined with elevated humidity accelerates aging processes, allowing engineers to observe failure mechanisms that would otherwise take a long time to appear under normal operating conditions.

How are the trends in choosing pulse generators changing in 2026?
2026年05月18日 17時22分48秒

If you've observed electronics labs in recent years, you'll notice that the way they choose pulse generators has changed considerably. Previously, most attention was focused on specifications. The higher the MHz, the more waveforms, or the larger the display, the more likely the generator was to be preferred because it gave the impression of being durable and not becoming obsolete in the long run

Features often overlooked when choosing a pulse generator
2026年05月18日 16時15分40秒

A pulse generator might look very powerful in a catalog, but when you actually test it in a real circuit, quite a few annoying issues start to emerge. Some models produce a beautiful sine wave but have slight ripple at the edges of the pulse; some require many steps to change the waveform; and some models develop a loss of smoothness in the rotary knob or noticeably slow menu response after only a few months of use

How does the switching power supply affect the pulse signal?
2026年05月18日 14時50分54秒

Sometimes, a pulse signal may appear perfectly normal at first glance, but when viewed on an oscilloscope, it reveals slight vibrations, uneven amplitude, or timing deviations in cycles. The first reaction is usually to check the pulse generator, connections, or output load. However, many errors originate from the power supply section, especially the switching power supply
