USB Logic Analyzer 24MHz 8-Channel Digital Debugging Tool

Specifications

• Sampling Rate: Up to 24MHz (Selectable: 24MHz, 16MHz, 12MHz, 8MHz, 4MHz, 2MHz, 1MHz, etc.).

• Channels: 8 Digital Channels (D0 to D7).

• Voltage Range: 0V to 5.25V (Standard CMOS/TTL levels).

• Logic Thresholds: Logic Low: < 0.8V; Logic High: > 2.0V.

• Input Impedance: 100kΩ, 5pF.

• Buffer Depth: Up to 10 billion samples (limited only by PC RAM).

• Software Support: Fully compatible with Saleae Logic and Sigrok PulseView.

• Connectivity: Mini-USB interface (powered via USB).

Key Applications & Projects

• Protocol Decoding: Automatically decode UART (RS232), I2C, SPI, CAN, 1-Wire, and DMX signals.

• Timing Analysis: Measure precise delays between interrupt triggers and hardware responses.

• Reverse Engineering: Analyse proprietary communication between existing devices.

• Educational Lab Tool: The perfect entry point for students learning digital electronics.

????Project Evolution

• Past Projects (Prerequisites): If you've been using a basic Digital Multimeter to check "high" or "low" states, you're ready for this.

• Feature Upgrade: This analyser unlocks Time-Domain Visualisation. You can finally "see" the data packets moving. While a multimeter indicates that a pin is "on," this tool provides a more specific interpretation (e.g., "Address 0x27: Read Success").

• Effort/Requirements: Intermediate. Requires installing open-source software (PulseView) and connecting the included Dupont probes to your target headers.

Virtual Technician & Wiring

⚠️ Safety Warning: Always connect the GND wire of the analyser to the GND of your target circuit before connecting signal leads. Avoid measuring signals above 5.25V.

Frequently Asked Questions (FAQ)

• Is this an original Saleae product? This is a high-quality compatible hardware module that works with Saleae-compatible software.
• Does it work with Windows 11? Yes, it is fully compatible with Windows 11, 10, and Linux.
• What software should I use? We recommend Sigrok PulseView (open-source) or Saleae Logic (v1.2.18).
• How many channels can I use at 24MHz? You can use all 8 channels, provided your USB controller has sufficient bandwidth.
• Can I measure 12V signals? No, the limit is 5.25V. Using 12V will damage the input buffer.
• Does it include the USB cable? Yes, a Mini-USB cable and 10-way Dupont jumper wires are included.
• Do I need an external power supply? No, it is entirely powered by the USB port of your PC.
• Can it decode CAN bus? Yes, it can decode CAN when used with a CAN transceiver or at TTL levels.
• What is the minimum logic high level? 2.0V, making it compatible with both 3.3V and 5V systems.
• Can it capture analog signals? No, this is a purely digital logic analyzer.
• How much memory does it have? It streams data to your PC, so the "memory" is limited by your computer's RAM.
• The software says "Device Not Found," what do I do? Usually, this is a driver issue; ensure you've installed the WinUSB driver via Zadig.
• Is it 1.8V logic compatible? It may work intermittently with 1.8V, but it is officially rated for 2.0V+ logic high levels.
• Does it support SPI protocol? Yes, it is excellent for debugging 4-wire SPI.
• Can it trigger on a specific pattern? Yes, you can set triggers for rising/falling edges or specific logic combinations.
• How long can I record for? At lower sample rates, you can record for hours if you have enough disk space/RAM.
• Is it safe to leave connected? Yes, but ensure the ground loop between your PC and target circuit is managed.
• Can I use it to decode remote control IR signals? Yes, it is perfect for analyzing NEC or Sony IR protocols.
• What is the input capacitance? Approximately 5pF, which is low enough for most hobbyist circuits.
• Is it original-grade silicon? Yes, we source verified Cypress-based controllers for stable USB enumeration.
