    Present True Signal
    The SigOFIT probe has an extremely high common-mode rejection ratio (CMRR) of 128 dB at 100 MHz and over 100 dB at 1 GHz, enabling faithful measurement of signals.

    Excellent amplitude-frequency response
    DC gain accuracy ≤ 1%, noise ≤ 0.45 mVrms, zero drift < 0.1% (after 5 minutes), gain drift < 1%.

    Optimum probe for 3rd generation semiconductors
    Devices such as SiC and GaN can switch high voltages, including very energetic high-frequency harmonics, in a few nanoseconds; SigOFIT has a CMRR of >100 dB even at maximum bandwidth, suppressing oscillations caused by high-frequency common-mode noise.

    Safety Performance
    The SigOFIT probe's short test leads and coaxial cable transmission make it very safe to test GaN with an input capacitance of less than 2.5pF. * Safety is not guaranteed if the device is already in a critical state.

    Wide measurement range
    Conventional differential probes can only measure high voltage signals, but the SigOFIT probe can measure differential mode signals from ±0.1V to ±6250 by using different attenuator chips, providing very high signal-to-noise ratios over an optimal range.
