The Yokogawa 702902 is a 10:1 isolated passive probe engineered for precision measurement in high-voltage test environments. Rated for ±1000 V (DC + ACpeak) across all measurement configurations, it delivers DC to 60 MHz bandwidth with minimal signal distortion. Galvanic isolation between the measurement tip and safety ground significantly reduces common-mode noise and eliminates ground loop artifacts, making it essential for differential measurements in industrial and laboratory applications. The probe features a 2.5 meter cable length, 10 MΩ input resistance, and 5.8 ns maximum rise time, ensuring accurate signal capture across transient and steady-state conditions. An isolated BNC connector integrates directly with ScopeCorder series isolated input modules. Built for demanding environments, it operates reliably from −40°C to +85°C without condensation and functions at altitudes up to 3,000 m.
