Rigol RP1025D – High Voltage Differential Probe, DC-25 MHz

The Rigol RP1025D is a high-voltage differential probe engineered for precision measurement of differential signals across industrial and R&D environments. With a bandwidth of DC to 25 MHz at X50 and X200 attenuation ratios, this probe captures detailed signal characteristics while maintaining high input impedance (4 MΩ / 1.2 pF or 100 MΩ / 1.2 pF differential) and minimal loading effects through low input capacitance. The probe handles differential voltages to 1400 Vpp maximum and accommodates common-mode voltages up to 600 Vrms, making it suitable for power electronics, motor drive analysis, and industrial control system diagnostics.
