Evidence-driven specs for power electronics benches.
HV-D150 High-Voltage Differential Probe
A 150 MHz high-voltage differential oscilloscope probe with 50X/500X attenuation, isolated USB-C power, and clear measurement limits for power electronics bench work.
Measurement-range limits are not CAT safety category ratings. Review the safety guide before use.

FAQ
Answers to common questions about HV-D150.
Is it isolated?
Yes. USB-C power is internally isolated. Always follow safety limits.
What’s the bandwidth?
Bandwidth (-3 dB): ≥ 150 MHz. Bandwidth (-0.5 dB): ≥ 80 MHz.
Max voltage?
Max differential input (measurement range, Vpeak): 50X up to ±180 Vpeak / 500X up to ±1.6 kV Vpeak (differential input). This is a measurement-range limit, not a CAT safety category. Over-voltage alert (buzzer/LED): ~1.8 kV Vpeak (tolerance ~1.75–1.85 kV).
Does it work with any oscilloscope?
Works with standard BNC 1 MΩ inputs.
Power requirements?
USB-C 5 V from a charger or scope USB.
Warranty?
12-month warranty.
Shipping from where?
Tracked shipping via YunExpress / 4PX (availability varies by region).
Do I pay import tax?
Depends on your country; see Shipping policy.
Can I measure mains?
Follow CAT/safety guidance; intended use is electronics bench measurements.
