Bandwidth: DC-1GHz
CMRR: DC-160dB
Common Mode Voltage: 60kVpk
DC Accuracy: 1%

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

Highest Accuracy
SigOFIT probe has excellent amplitude-frequency characteristics, 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 500μV 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 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
The test leads of SigOFIT probe 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.

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 ±1.25V to ±2500V, achieve full-range output and very high signal-to-noise ratio.

Efficient & Affordable
Fastest response, can be tested immediately after power-on; AutoZero completed in less than 1 second, ensures accurate signal output in real time.

Applications
* Design of motor drive, power converter, electronic ballast
* Design of GaN, SiC, IGBT Half/Full bridge devices
* Design of inverter, UPS and switching power supply
* Safety test for high voltage, high bandwidth applications
* Power device evaluation
* Current shunt measurements
* EMI & ESD troubleshooting
* Floating measurements
