SIGLENT can provide customers with high-accuracy power rail measurement solution. The SAP4000P power rail probe covers power rail transient events up to 4 GHz, and its low-noise feature helps to differentiate between the oscilloscope and probe noise and the ripple and noise of the DC power supply under test. The ±24 V offset voltage range makes it easy to adjust dynamic signals with a DC component near the centerline of the oscilloscope’s screen, and It also offers a wide dynamic range of ±600mV, which on higher voltage rails, lets you look at droop on the line or when a lot of current is drawn by load or transients. In addition, the high 50 kΩ impedance at low frequencies eliminates load effects and minimizes interference with the power supply under test, while the low 50 Ω impedance at high frequencies matches coaxial cables and increases test bandwidth.
