N1010A FlexDCA Sampling Oscilloscope Software

N1010A FlexDCA Sampling Oscilloscope Software provides Oscilloscope, Eye/Mask, Jitter, and TDR measurement capabilities and is used to control compatible Keysight DCA instruments.

The FlexDCA installer includes the latest updates* for:

FlexDCA software packages: N1010100A R&D, N1010200A MFG, and N1010300A SI
FlexPLL for phase-locked loop measurements
FlexRT for optical measurements on UXR-Series Oscilloscopes
FlexOTO for optimization of optical measurements using DCA-M Series oscilloscopes

* Requires applicable software licenses with active support

No licenses are required for basic FlexDCA functionality. Trial licenses are available to evaluate licensed features before purchase: N1010100A, N1010200A, N1010300A, N1002000A, N1002014A, N1002048A, N1002128A
