With the continuous updates in hardware architecture, oscilloscopes are no longer just instruments for “oscillography”; protocol decoding is a typical example! IIC, SPI, UART, CAN, LIN… We provide the ZDS series oscilloscopes with up to 37 types of protocol decoding analysis plugins for free. What are the applications of these numerous protocols, and how are they specifically used?

II. What protocols do oscilloscopes support?
Currently, oscilloscopes can decode not only well-known protocols such as CAN, UART, IIC, and USB but also many other protocols. We categorize them based on industry frameworks.

III. Are ZDS Series Oscilloscopes Charged?
All protocol decodings for the ZDS series oscilloscopes are provided for free, with support for over 30 types of protocol decoding. The decoding can be displayed in three formats: “Decimal”, “Hexadecimal”, and “Character”, as shown in Figure 7.

Additionally, it supports detailed decoding displays, featuring a comprehensive event table (the event table includes start time, end time, name, and data), which can be exported in report web or CSV format for further analysis by engineers, as shown in Figure 8.
