Silicon carbide suitable

This high voltage fiber optic probe is perfect for device research engineers designing silicon and silicon carbide devices, and system development engineers incorporating Silicon Carbide devices.

Upper-side gate drive signal measurements

This probe faithfully reproduces upper-side gate drive signals without loading and distortion, allowing a clear view of the Miller effect. Any conventional HV differential probe with high tip capacitance in parallel with CGE or CGS, and/or high impedance and large loop inductance in series with the gate drive impedance will at best load the gate drive signal or pick up interference and at worst cause circuit malfunction. This probe performs much better for these measurements.

Floating control or sensor signal measurements

This probe measures only the low voltage sensor voltage across its high impedance input leads. Total load on the device under test (DUT) is very small. Furthermore, the low lead loop inductance, above 100 dB CMRR, and low attenuation provide superior signal fidelity, noise and rejection.

EMC, EFT, ESD and RF immunity testing and system optimization

AC and DC sensor signals floating at a high voltage or in the presence of EMC disturbance signals can be acquired with high signal fidelity and correctly correlated to in-circuit and control activities.

Optical isolation is best

Optical isolation between the probe tip and the oscilloscope input ensures safety against dangerous high voltage levels, reduces adverse DUT loading, provides faithful pulse response, and increases measurement confidence.

Superior noise rejection

High CMRR (140 dB) provides more accurate representation of the measured signal despite the presence of high dV/dt or dA/dt events elsewhere in the circuit. The test lead is optimized to limit loop inductance and radiated pickup. Tip attenuations are optimized for a wide range of signal amplitudes.

Compact, simple, affordable

This probe fits into tight spaces as well as tight budgets, without sacrificing performance.
