A logic analyzer is a type of electronic testing equipment used to analyze digital signals. It is used to capture and display the state of digital signals at a certain point in time. It can be used to troubleshoot digital circuits, to detect errors in digital designs, or to debug digital systems.
Logic analyzers come in a variety of sizes and capabilities. Some are handheld devices that can be used in the field, while others are large, rack-mounted systems that are used in a laboratory setting. The price range of logic analyzers can vary greatly, depending on the features and capabilities of the device. For example, a basic handheld logic analyzer may cost around $200, while a high-end, rack-mounted system may cost several thousand dollars.
There are many manufacturers of logic analyzers, including Tektronix, Keysight Technologies, Rohde & Schwarz, and National Instruments. Each of these companies has a wide range of products, ranging from basic handheld devices to sophisticated rack-mounted systems.
