# Title: Hantek HT8100 High-Voltage Differential Probe 100MHz


## Description: Overview The Hantek HT8100 high-voltage differential probe represents essential test equipment for power electronics engineers working with floating circuits, switching power supplies, and motor drive systems. Unlike standard oscilloscope probes that reference measurements to ground, this differential probe safely measures voltage differences between two floating points whilst providing galvanic isolation from the oscilloscope ground plane. Key Applications Power Electronics Design Essential for measuring drain-to-source voltages (VDS) in MOSFETs, collector-emitter voltages in IGBTs, and voltage drops across freewheeling diodes in half-bridge and full-bridge configurations. The probe's 100MHz bandwidth captures fast switching transients in modern SiC and GaN power devices. Motor Drive Systems Critical for analysing three-phase inverter outputs, measuring phase-to-phase voltages, and debugging PWM modulation schemes without creating dangerous ground loops through the measurement system. Switching Power Supply Debug Enables safe measurement of transformer primary and secondary voltages, isolation barrier testing, and ripple analysis in flyback, forward, and LLC resonant converters. Technical Specifications Parameter HT8100 Specification Bandwidth (-3dB) 100MHz Rise Time ≤3.5ns Attenuation Ratios 1:50, 1:500 (user selectable) Maximum Differential Voltage ±130V (1:50), ±1300V (1:500) Common Mode Input Range 1000Vrms CAT II, 600Vrms CAT III Input Impedance 4MΩ±1% (single-ended), 8MΩ±1% (differential) Input Capacitance ≤8pF (single-ended), ≤4pF (differential) CMRR ≥80dB (DC), ≥60dB (100Hz), ≥50dB (1MHz) Accuracy ±2% Noise Floor ≤2mVrms (1:50), ≤1mVrms (1:500) Safety Considerations Warning: Always verify circuit de-energisation before connecting probe tips. The CAT III rating provides protection against transients but does not eliminate shock hazards from direct contact with live conductors. The HT8100's safety certification covers both installation categories: CAT II for outlets and plug-connected equipment, and CAT III for distribution panels and fixed installations. The over-voltage detection system provides visual warning when inputs exceed ±140V (1:50 range) or ±1400V (1:500 range), protecting both probe and measurement equipment. Connection and Setup Physical Connections The probe features colour-coded input leads: red for positive input, black for negative input. Standard BNC output connects to any oscilloscope channel. The external AC adapter supplies isolated DC power, eliminating dependence on oscilloscope probe power interfaces. Grounding Strategy Unlike single-ended probes, the HT8100 requires no ground connection to the circuit under test. This floating operation prevents ground loops whilst maintaining measurement accuracy through excellent common-mode rejection specifications. Measurement Techniques MOSFET Drain-Source Voltage // Typical VDS measurement setup 1. Set oscilloscope to DC coupling 2. Select appropriate probe attenuation (1:50 for <130V, 1:500 for >130V) 3. Connect red lead to MOSFET drain 4. Connect black lead to MOSFET source 5. Configure oscilloscope vertical scale: Vpp_expected / attenuation_ratio / 8 6. Set trigger on rising edge at 10% of expected voltage Isolation Testing For transformer isolation measurements, connect probe inputs across the isolation barrier. The high CMRR specification ensures accurate measurement of small differential signals even with kilovolts of common-mode voltage present on both windings. Comparison with Alternatives Approach Safety Accuracy Cost Limitations HT8100 Differential Probe CAT III rated ±2%, >50dB CMRR Moderate 100MHz bandwidth limit Two Single-Ended Probes (Math) Poor Poor CMRR Low Ground loop risk Isolated Oscilloscope Excellent Excellent Very High Equipment cost Optically Isolated Probe Excellent Excellent Very High Complexity, cost Maintenance and Calibration Annual calibration verification ensures continued measurement accuracy. Check probe compensation using the oscilloscope's built-in calibration signal, and inspect input cables for damage that could compromise safety ratings. The probe requires 20-minute warm-up for specified accuracy performance. Environmental Limits: Operating temperature 0-40°C, storage temperature -10 to 45°C, maximum altitude 3000m operational. Troubleshooting Common Issues No Signal Display Verify AC adapter connection and green POWER LED illumination Check BNC cable connection to oscilloscope input Confirm oscilloscope channel is enabled and properly scaled Measurement Instability Twist input leads together to reduce noise pickup Avoid extending input cables beyond supplied length Ensure probe and oscilloscope have completed 20-minute warm-up Over-Range Indication Red LED warning indicates input voltage exceeds selected range Switch to higher attenuation ratio (1:500) for voltages above 130V Verify circuit voltage levels before connection

- 1569478: What is the maximum differential voltage the HT8100 can measure?***SIMP***The HT8100 can measure up to ±130V (DC + peak AC) on the 1:50 range and ±1300V (DC + peak AC) on the 1:500 range, making it suitable for most power electronics applications.
- 1569479: Is this probe safe for measuring mains-powered circuits?***SIMP***Yes, the HT8100 has CAT II 1000V and CAT III 600V safety ratings with maximum common-mode input voltage of 1000Vrms CAT II or 600Vrms CAT III, making it suitable for industrial power measurements.
- 1569480: What bandwidth does the HT8100 offer for high-frequency measurements?***SIMP***The probe provides 100MHz bandwidth (-3dB) with ≤3.5ns rise time, adequate for capturing switching transients in most modern power converters including SiC and GaN devices operating below 100MHz.
- 1569481: Can I use this probe with any brand of oscilloscope?***SIMP***Yes, the HT8100 features standard BNC output connectivity and is compatible with all oscilloscope brands. It includes its own power supply and does not require oscilloscope probe power interfaces.
- 1569482: How does the over-range warning system work?***SIMP***The probe includes visual over-range detection with red LED warning lights that activate when input voltage exceeds the selected measurement range (≥130V for 1:50 range, ≥1300V for 1:500 range).
- 1569483: What accessories are included with the HT8100?***SIMP***The complete package includes the probe body, AC power adapter (DC9V 1000mA), red and black alligator clips, red and black pincer clips, BNC output cable, and instruction manual.
- 1569484: What is the common-mode rejection ratio specification?***SIMP***The HT8100 provides excellent CMRR performance: ≥80dB at DC, ≥60dB at 100Hz, and ≥50dB at 1MHz, ensuring accurate differential measurements even with high common-mode voltages present.
- 1569485: How long are the input cables for measurement flexibility?***SIMP***The HT8100 features approximately 25cm input cable length and 90cm output cable length, providing sufficient reach for most measurement scenarios whilst minimising noise pickup.
- 1569486: What input impedance does the probe present to the circuit?***SIMP***Input impedance is 4MΩ±1% from each input to ground and 8MΩ±1% between the two inputs, with input capacitance ≤8pF single-ended to ground and ≤4pF between inputs.
