Siglent Power Rail Oscilloscope Probes
Uncover Hidden Noise on Your DC Supplies Modern digital circuits require incredibly “clean” power, but measuring millivolt-level ripple on a 12V or 48V rail is difficult for standard probes. Siglent Power Rail Probes are purpose-built for Power Integrity (PI) testing. With massive offset capability and ultra-low noise, they allow you to DC-couple your signal and zoom in on the smallest transients, noise, and periodic interference riding on your DC rails.
