Tips: What are the advantages of a handheld oscilloscope?

A portable oscilloscope is a very versatile electronic measuring instrument. It can convert invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with a fluorescent material to produce a small spot of light (this is the working principle of a traditional analog oscilloscope). Under the action of the signal under test, the electron beam is like the tip of a pen, which can draw the change curve of the instantaneous value of the signal under test on the screen. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing with time, and it can also be used to test various electric quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc.

The portable oscilloscope is used to display the change of the track of the measured instantaneous value and has the characteristics of easy portability and simple operation. It can convert invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena. The oscilloscope has the performance and features of a larger oscilloscope at a portable, affordable price.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
