High performance differential probe

Say goodbye to complex settings! BNC plug-and-play design simplifies workflow,. Users can take power through the USB-C power supply or oscilloscope port, flexible to adapt to the mobile detection environment. One-handed operation can complete the inverter pulse signal capture, improve the efficiency of automotive electronic diagnosis.

Measuring advantages

When measuring PCIe 4.0 differential signals, the probe's 70MHz bandwidth and ≤ 5ns rise time accurately restore 200mV eye diagram, and the input capacitance ＜2pF avoids ground bounce effect. The isolation layer of the isolation substrate realizes the isolation impedance of 10 12Ω, which can not only guarantee the signal transmission but also guarantee the zero common ground damage between the oscilloscope and the board card to be tested.

CMRR Common Mode Rejection Capability

20mVrms low noise works with 80dB CMRR. Hall effect technology combined with dynamic compensation algorithm can realize 2% precision signal acquisition in industrial automation control system, and provide closed-loop feedback without drift for PLC control system.

Overlimit alarm

One-button sound and light alarm control function: press the button for the first time to light up the operation indicator (ON LED) and activate the over-limit alarm system. When the measured signal exceeds the preset threshold, double alarm will be given through buzzer sound and visual indication. Press the button again to switch to silent mode and disable sound prompt.

Fast signal measurement

In high-speed falling edge measurement, the traditional probe is prone to ringing distortion due to insufficient bandwidth or load effect, resulting in waveform overshoot and oscillation. This product adopts differential architecture and broadband response design, which can accurately capture sub-nanosecond edge characteristics and effectively suppress reflected waves and parasitic oscillations. Through the built-in de-embedding algorithm and adjustable attenuation ratio, it is especially suitable for switching characteristics analysis of SiC/GaN devices and dead time optimization of motor controllers, providing a distortion-free measurement solution for dynamic response verification of high frequency power conversion systems.
