The Yokogawa 702911 High Speed Logic Probe captures and analyzes high-speed digital signals with 8-bit resolution and sub-microsecond response. This non-isolated TTL-level probe integrates directly with Yokogawa logic analyzers, oscilloscopes, and data acquisition platforms for real-time signal debugging and protocol analysis.
Technical Specifications
• Resolution: 8-bit
• Response Speed: 3 µs or less
• Input Type: TTL level, non-isolated contact input
• Threshold Level: Approximately 1.4 V
• Cable Length: 1 meter (702911 model)
– Key Features
The probe’s 3 µs or faster response speed enables capture of high-frequency digital events without signal degradation. TTL threshold operation at 1.4 V accommodates standard logic families and embedded system signal levels. Non-isolated design eliminates ground loop complications in single-ended measurement configurations. Compact contact input clips interface directly with test points and component leads.
– Typical Applications
• Embedded system firmware debugging
• Serial protocol analysis (I2C, SPI, UART)
• Mixed-signal design verification
• Digital circuit timing analysis
• Real-time signal capture during system operation
– Compatibility & Integration
The 702911 connects to a broad range of Yokogawa instruments: DL350, DL850/DL850E/DL850EV, DL950, SL1000, DLM oscilloscopes, and ScopeCorder units. Integration with Logic Input Module 720230 extends measurement capability across multi-channel acquisition setups. Extended 3-meter cable variant (7012 model) accommodates remote measurement locations where standard 1-meter leads prove restrictive. Accessory ecosystem includes pin clips (B9852ES), synchronous cables (720901 series), and adapter configurations (BNC, banana, D-Sub) for varied test point geometries.
