In the era of Smart Manufacturing and Digital Factories, managing and tracing product origins through barcodes (Barcode/Data Matrix) has become a rigorous standard.

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

When looking to buy a depth gauge, many people immediately look at the resolution because smaller numbers often give the impression of being more high-end. A display with 0.001 mm accuracy is quite appealing, especially with newer electronic models.

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

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
