The KSO series PXIe Oscilloscopes and the KDZ series PXIe High-Speed Digitizers are based on a same design origin, but they have distinct functional differences.

Compared to the KDZ series High-Speed Digitizers, the KSO series PXIe Oscilloscopes include additional channel control and signal conditioning paths. While their analog bandwidth is lower than that of the digitizers, they can acquire a wider range of input signal amplitudes and feature functions such as switchable high/low impedance and AC/DC coupling.
