Tips: What does bandwidth mean in a digital oscilloscope?

Bandwidth is one of the most important specifications of an oscilloscope. The bandwidth of an analog oscilloscope is a fixed value, while the bandwidth of a digital oscilloscope has two types: analog bandwidth and digital real-time bandwidth. The digital real-time bandwidth of the digital oscilloscope is the digital real-time bandwidth of oscilloscope, which can be achieved by using sequential sampling or random sampling technology for repetitive signals. The digital real-time bandwidth is related to the highest digitization frequency and waveform reconstruction technology factor K (digital real-time bandwidth = maximum digitization rate/K), generally not directly given as an indicator. It can be seen from the definitions of the two bandwidths that the analog bandwidth is only suitable for the measurement of repetitive periodic signals, while the digital real-time bandwidth is suitable for the measurement of both repetitive signals and single-shot signals. When measuring a single signal, be sure to refer to the digital real-time bandwidth of the digital oscilloscope, otherwise, it will bring unexpected errors to the measurement.

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.
