The Micsig DP Series High-Voltage Differential Probe delivers exceptional measurement fidelity for professional engineers testing high-voltage and floating signals. Available in comprehensive bandwidth variants from 100 MHz to 500 MHz (models DP700-DP705) and voltage ranges from 700 Vpk to 7000 Vpk (models DP700-DP7005), this probe series excels at power electronics, motor drives and semiconductor testing applications.
Superior Signal Integrity with Advanced SigOFIT Technology
Built on Micsig's proven SigOFIT technology, the DP Series achieves industry-leading common-mode rejection ratio of >80 dB at DC and >60 dB at 100 kHz. Ultra-low noise floor (as low as 5 mVrms) and excellent bandwidth flatness (<0.5 dB amplitude variation) ensure accurate differential readings free from common-mode interference. High input impedance (up to 60 MΩ) and minimal capacitive loading (<3 pF) preserve circuit integrity during measurements.
Enhanced Usability and Safety Features
Compact 2cm-thin metal housing provides robust EMI protection whilst standard BNC interface guarantees compatibility with any 50 Ω oscilloscope. One-press auto-zero calibration, dual-range attenuation switching and visual/audible overvoltage alarms simplify operation and enhance safety. USB-powered operation eliminates battery concerns during extended measurements. Engineers requiring even higher isolation can explore our SigOFIT Optical-Fibre Isolated Probe series for applications demanding up to 180 dB CMRR.
