Each of the eight inputs can be configured for digital or analogue capture, with digital sample rates up to \u003cstrong\u003e100 MS\/s on three channels\u003c\/strong\u003e or \u003cstrong\u003e25 MS\/s on all eight\u003c\/strong\u003e, and analogue sampling up to \u003cstrong\u003e10 MS\/s at 10-bit resolution\u003c\/strong\u003e (≈1 MHz bandwidth). Combined with unlimited USB streaming and built-in protocol decoding for SPI, I²C, UART, CAN and more, it provides a powerful, compact tool for rapid debugging and validation.\u003c\/p\u003e\n\n  \u003ch3\u003eMixed-Signal Capture on Every Channel\u003c\/h3\u003e\n  \u003cp\u003eAll eight inputs can capture both digital and analogue signals simultaneously. With ±25 V input protection and software-adjustable thresholds, the Logic 8 connects safely to logic families from \u003cstrong\u003e1.2 V up to 5.5 V\u003c\/strong\u003e. For example, you can watch an I²C transfer at \u003cstrong\u003e400 kHz\u003c\/strong\u003e while monitoring the 3.3 V rail’s droop at the same instant. This makes it possible to identify not only that a transaction failed, but exactly why, by correlating protocol errors with analogue behaviour. The benefit is confidence in diagnosing root causes without switching between instruments.\u003c\/p\u003e\n\n  \u003ch3\u003eSampling Performance for Embedded Systems\u003c\/h3\u003e\n  \u003cp\u003eThe Logic 8 offers a \u003cstrong\u003e100 MS\/s digital sample rate\u003c\/strong\u003e with three channels enabled, \u003cstrong\u003e50 MS\/s with six channels\u003c\/strong\u003e, and \u003cstrong\u003e25 MS\/s when all eight are active\u003c\/strong\u003e. Its analogue mode records at \u003cstrong\u003e10 MS\/s, 10-bit\u003c\/strong\u003e resolution, with about \u003cstrong\u003e1 MHz analogue bandwidth\u003c\/strong\u003e. This covers most microcontroller buses such as SPI up to 25 MHz, UARTs at several Mbaud, and CAN or LIN networks, while also capturing analogue effects like ringing, crosstalk, and ground bounce. The benefit is full visibility of both the digital logic and the analogue environment that affects it.\u003c\/p\u003e\n\n  \u003ch3\u003eUnlimited Streaming for Rare Event Detection\u003c\/h3\u003e\n  \u003cp\u003eRather than relying on a small on-device buffer, the Logic 8 streams data continuously over USB 2.0 into host RAM. Capture depth is limited only by your computer’s memory, allowing sessions that last minutes or hours. This capability is essential for catching elusive issues such as a watchdog reset after \u003cstrong\u003e45 minutes of runtime\u003c\/strong\u003e, or a UART framing error that appears once every \u003cstrong\u003e10,000 frames\u003c\/strong\u003e. The benefit is that rare and intermittent faults can finally be recorded and analysed with full timing context.\u003c\/p\u003e\n\n  \u003ch3\u003eProtocol Analysis Made Simple\u003c\/h3\u003e\n  \u003cp\u003eThe Logic 2 software provides built-in support for more than \u003cstrong\u003e20 protocol analysers\u003c\/strong\u003e, including SPI, I²C, UART, CAN, LIN, MDIO and USB Low\/Full-Speed. Decoded frames appear directly on the captured waveforms, aligned with the original edges. For example, you can inspect an \u003cstrong\u003eSPI command at 12 MHz\u003c\/strong\u003e, see the data bytes decoded, and immediately correlate them with the analogue waveform. This eliminates manual decoding and dramatically reduces debug time, while ensuring protocol correctness and electrical integrity are considered together.\u003c\/p\u003e\n\n  \u003ch3\u003eFlexible Logic Levels and Safe Probing\u003c\/h3\u003e\n  \u003cp\u003eWith support for logic families from \u003cstrong\u003e1.2 V up to 5.5 V\u003c\/strong\u003e and robust ±25 V protection, the Logic 8 can be safely connected to modern low-voltage microcontrollers, 3.3 V sensors, and legacy 5 V devices. Software-controlled thresholds allow precise adaptation to the system under test. The benefit is reliable probing across a wide range of designs without risking damage to the analyser or your circuit.\u003c\/p\u003e\n\n  \u003ch3\u003eEveryday Debugging Scenarios\u003c\/h3\u003e\n  \u003cp\u003eThe Logic 8 is just as valuable for simple checks as for complex investigations. It can confirm that a UART running at \u003cstrong\u003e1 Mbaud\u003c\/strong\u003e is transmitting correctly, verify that an I²C EEPROM responds at \u003cstrong\u003e100 kHz\u003c\/strong\u003e, or ensure that an SPI DAC receives a \u003cstrong\u003e16-bit configuration word within 10 ms of reset\u003c\/strong\u003e. For longer sessions, continuous streaming makes it possible to capture CAN arbitration errors that only occur during heavy load, or to log a serial console until a random missing character appears. The benefit is clear visibility of both routine protocol traffic and hard-to-find faults.\u003c\/p\u003e\n\n  \u003ch3\u003ePortable and Cross-Platform\u003c\/h3\u003e\n  \u003cp\u003eMeasuring just \u003cstrong\u003e53 × 53 × 12 mm\u003c\/strong\u003e and weighing around \u003cstrong\u003e60 g\u003c\/strong\u003e, the Logic 8 is compact and USB-powered, requiring no external supply. It is easy to move between benches or bring to a customer site. The Logic 2 software runs on Windows, macOS and Linux, and captures can be shared without the hardware attached. The benefit is a highly portable tool that fits seamlessly into collaborative workflows across different environments.\u003c\/p\u003e\n\n  \u003ch3\u003eWhy Engineers Choose Logic 8\u003c\/h3\u003e\n  \u003cp\u003eBy combining \u003cstrong\u003e8 mixed-signal channels\u003c\/strong\u003e, \u003cstrong\u003e100 MS\/s digital sampling\u003c\/strong\u003e, \u003cstrong\u003e10 MS\/s 10-bit analogue capture\u003c\/strong\u003e, support for \u003cstrong\u003e1.2–5.5 V logic\u003c\/strong\u003e with ±25 V protection, and unlimited USB streaming, the Saleae Logic 8 delivers the performance needed to solve both everyday debug tasks and elusive intermittent failures.

Engineers can, for example, decode I²C while simultaneously examining pull-up strength and rise times, or verify SPI timing while checking analogue overshoot on SCLK or MOSI. This reduces fixture changes, eliminates probe re-arrangement, and shortens time-to-insight—especially when intermittent edges, crosstalk or power-rail coupling are at play.

Practically, that means you can inspect a 50 MHz SPI clock’s duty cycle, verify UART sampling points well beyond 1 Mbaud, and confirm I²S\/PCM frame timing while checking analogue rail droop during burst activity—all in a single session. USB 3.0 is required for maximum rates; the software adapts available sample-rate\/channel combinations automatically to the host’s bandwidth. :contentReference[oaicite:2]{index=2}\u003c\/p\u003e\n\n  \u003ch3\u003eSignal Integrity: Protection, Impedance and Grounding That Respect Your DUT\u003c\/h3\u003e\n  \u003cp\u003eThe input front end is engineered to be present but unobtrusive.

Engineers can export data to CSV, VCD, binary or MATLAB for post-processing, automate repetitive tasks via the Automation API, or extend capability with custom protocol decoders. This combination of decode breadth and workflow tooling shortens root-cause analysis from hours to minutes on typical embedded bring-up and regression investigations. :contentReference[oaicite:4]{index=4}\u003c\/p\u003e\n\n  \u003ch3\u003eDeep, Practical Recording: Long Runs without Losing Detail\u003c\/h3\u003e\n  \u003cp\u003eRather than a fixed internal memory, captures stream over USB to host RAM, making \u003cem\u003erecording length primarily a function of installed memory and data activity\u003c\/em\u003e.
