Key Features
Overview
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.

Frequently Asked Questions
Have a Question?
-
What maintenance is required for long-term reliability?
Perform auto-zero calibration periodically, protect probe tips from mechanical damage, and store in provided case when not in use.
-
How do I minimise noise in sensitive measurements?
Use dual-range selection for optimal signal-to-noise ratio, enable 5 MHz bandwidth limiting when appropriate, and ensure proper probe compensation.
-
Which oscilloscope brands are compatible with DP Series probes?
Standard BNC interface ensures compatibility with Tektronix, Keysight, Rohde & Schwarz, LeCroy, Rigol and all other 50Ω input oscilloscopes.
-
What makes the DP Series suitable for floating measurements?
High common-mode voltage capability combined with excellent CMRR allows safe measurement of signals referenced to high potentials without ground loops.
-
How accurate are measurements across the specified bandwidth?
The DP Series maintains <0.5 dB amplitude flatness within half-bandwidth and ±2% DC accuracy across all attenuation ranges.
-
Can I use the 5 MHz bandwidth limit for switch-mode power supply measurements?
Yes, bandwidth limiting (available on 100-200 MHz models) effectively eliminates high-frequency switching noise whilst preserving fundamental waveform information.
-
What safety certifications do DP Series probes maintain?
All models meet CAT II 600V safety ratings with appropriate common-mode voltage handling up to 7000V depending on model selection.
-
How does CMRR performance compare to premium solutions like Tektronix THDP series?
The DP Series achieves >80 dB CMRR at DC comparable to premium probes whilst offering superior value and universal oscilloscope compatibility.
-
Which bandwidth should I select for high-speed switching measurements?
For GaN and SiC power devices choose 300-500 MHz models (DP703-DP705). For traditional silicon devices 100-200 MHz variants (DP700-DP702) provide excellent performance.
-
What voltage ranges are available across the DP Series models?
The DP Series offers four voltage ranges: 700 Vpk (DP700-DP705), 1500 Vpk (DP1500-DP1505), 3000 Vpk (DP3000-DP3005), and 7000 Vpk (DP7000-DP7005) models with corresponding bandwidth options.
