Micsig SigOFIT 350MHz Optical-fiber Isolated Probe (MOIP350P)

With Micsigs exclusive SigOFIT optical isolation technology, the SigOFIT series probe can be powered by laser, delivers extremely high CMRR and isolation voltage, help engineers to see the whole truth of the signal within its bandwidth.

Present True Signal

SigOFIT series probe has highest common mode rejection ratio, or CMRR, up to 112dB at 100MHz, over 100dB at 500MHz. It is the ultimate referee of signal fidelity measured by other voltage probes.

Highest Accuracy

The SigOFIT probe has excellent amplitude-frequency characteristics, effective accuracy bandwidth [1] is as high as more than 50% of the nominal bandwidth. Within the effective accuracy bandwidth, the test accuracy of 1.5% can be guaranteed, and the DC gain accuracy is better than 1%. The maximum noise floor within the range is 1.41mVrms, and zero drift is less than 500u V after warm-up.

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 probes still have nearly 100dB CMRR, perfectly suppressed the oscillation caused by high-frequency common-mode noise, no redundant components. It is the best choice for 3rd-gen semiconductor test & measurement.

Safe to Test GaN

The test leads of SigOFIT probes are short and with coaxial cable transmission, has less than 3pF 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 3pF more capacitance added when connected to the DUT, safety hence is not guaranteed.
