Yokogawa 702912 High Speed Logic Probe

The Yokogawa 702912 High Speed Logic Probe is a non-isolated, 8-bit logic probe engineered for rapid digital circuit analysis and troubleshooting. It identifies logic states—high, low, or pulse—across modern digital systems with a response time of 3 µs or less, making it suitable for time-critical signal verification tasks.

– Technical Specifications

• Resolution: 8-bit
• Response Time: 3 µs or less
• Input Type: TTL level/Contact Input
• Threshold Level: Approximately 1.4 V
• Input Voltage Range: ±35 V (DC + AC peak)
• Input Impedance: 10 kΩ or more
• Cable Length: 3 meters

– Key Features

• Ultra-fast 3 µs response time for high-speed logic measurement
• TTL-compatible threshold at 1.4 V nominal
• High input impedance (10 kΩ minimum) minimizes circuit loading
• Wide voltage acceptance up to ±35 V (DC + AC peak) accommodates diverse signal levels
• 3-meter probe cable enables reach across larger test fixtures and PCBs

– Typical Applications

• Digital circuit troubleshooting and signal state verification
• TTL and CMOS logic level monitoring
• Real-time pulse detection in digital systems
• Multi-point logic analysis using 8-bit parallel measurement
