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.
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%.
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.
The test leads of SigOFIT probe are short and with coaxial cable transmission, the input capacitance is as low as 1pF minimum, very safe to test GaN.
Lasers transmit signals + Power over fiber (no batteries needed, the power supply is more pure), realizes continuous test for 365 days.
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 ±0.01V to ±6250V, achieve full-range output and very high signal-to-noise ratio.
Fastest response, can be tested immediately after power-on; AutoZero completed in less than 1 second, ensures accurate signal output in real time.
