Description


Micsig SigOFIT MOIP350P, 350MHz, Optical-fiber Oscilloscope Isolated Probe

Introducing the Micsig SigOFIT™ Probe, designed with exclusive optical isolation technology for unparalleled signal accuracy. With up to 100MHz bandwidth and a common-mode rejection ratio (CMRR) of 180dB at DC, this probe ensures precise testing of differential signals from ±0.01V to ±6250V. It’s the ideal tool for high-voltage, high-bandwidth applications such as GaN and SiC device testing, motor drive design, and power converters.

Perfect for engineers working on high-frequency, high-voltage applications, the SigOFIT probe provides true signal integrity, even in the most demanding conditions.

Real Optical Isolation Technology<br /> <br /> Lasers transmit signals + Power over fibre (no batteries needed, the power supply is more pure), realizes continuous test for 365 days.

Real Optical Isolation Technology

Safe to Test GaN<br /> <br /> 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.

Safe to Test GaN

Best Probe for Third-Gen Semiconductor<br /> <br /> SiC & GaN device can switch high voltages in a few nanoseconds, the signal may have high-energy high-frequency harmonics.<br /> <br /> 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.
