LeCroy HVD3206A High Voltage Differential Probe, 120MHz

The LeCroy HVD3206A is a high-voltage differential probe designed for precision measurement of differential signals in the presence of high common-mode voltages. Operating at 120 MHz bandwidth, it delivers minimal circuit loading through high input impedance and low input capacitance while maintaining superior common-mode rejection. The probe handles differential voltage ranges to ±1500 V and common-mode voltages to ±7000 V, making it essential for power electronics, automotive, and industrial control applications requiring signal integrity across demanding voltage environments.
