The logic analyzer will measure the difference between the reference voltage and signal voltage on each line. Trigger: The condition(s) necessary that cause the logic analyzer to begin sampling and recording data. Each has a "data in" line (labeled D0 or D1), a "data out" line (labeled Q0 or Q1), and a clock line (clk). On each rising edge of the clock signal, the logic level at the "data in" pin is latched and replicated on the "data out" pin. We will define a few key terms and give examples of decisions you must make at each step to help you analyze your system.

Details of each area can be found in the product data sheets, in the technical specifications on the Saleae home page, or in the user's guide. If a transmission bus relies on a clock line, this can be a useful way to visualize data in the same way your receiver sees it. Most logic analyzers will have a way to set your sampling mode, sampling rate, and triggers through a set of onscreen menus. A pattern trigger can be set by selecting multiple channels and setting channel state options, such as logic high or logic low.Some logic analyzers come with the ability to decode various communication protocols, such as UART, SPI, I2C, etc.

Most logic analyzers will display data as waveforms with time in the x-axis and logic state (1 or 0) in the y-axis. In the image below, we can see how a single logic analyzer channel will sample a sine wave at precise intervals.Extremely long sample buffers—in seconds, minutes, or even hours—lets you simply capture all activity at once without the need for complex triggering or modifications to your own design. In timing mode, also known as "asynchronous mode," data is captured at precise intervals according to the logic analyzer's internal clock. To view the captured data in greater detail, most logic analyzers will let you scroll or zoom using buttons or knobs.
