Present True Signal

Present True Signal

SigOFIT probe has highest common mode rejection ratio, or CMRR, up to 128dB at 100MHz, over 100dB at 1GHz. It's the ultimate referee of signal fidelity measured by other voltage probes.

Highest Accuracy

Highest Accuracy

As the ultimate referee of signal fidelity, SigOFIT optical-fiber isolated probe delivers highest test accuracy. It has excellent amplitude-frequency characteristics, DC gain accuracy ≤1%, while noise ≤ 0.45mVrms. Zero drift<0.1% (works 5 mins later), gain drift also <1%.

Third-Gen Semiconductor

Best Probe for Third-Gen Semiconductor

SiC & GaN device can switch high voltages in a few nanoseconds, the signal may have high-energy high-frequency harmonics.


Even at the highest bandwidth, the SigOFIT probe still have nearly 100dB CMRR, perfectly suppressed the oscillation caused by high-frequency common-mode noise, no redundant components. It's the best choice for 3rd-gen semiconductor test & measurement.

Safe to Test GaN

Safe to Test GaN

The test leads of SigOFIT probe are short and with coaxial cable transmission, has less than 2.5pF input capacitance, very safe to test GaN.


* When the working parameters of the device are already in the critical state of explosive, there will be nearly 2.5pF more capacitance added when connected to the DUT, safety hence is not guaranteed.

Optical-fiber Isolated Probe OP

Wide Measurement Range

Unlike traditional differential probes can only test high-voltage signals, SigOFIT probe can be used with different attenuator tips to test differential mode signals from ±0.1V to ±5000V, achieve full-range output and very high signal-to-noise ratio.
