As described in Section HVI Technology: Keysight M3601A , Keysight’s HVI technology provides the capability to create time-deterministic execution sequences that are executed by the Keysight M3XXXA PXIe hardware. HVIs are programmed with Keysight M3601A, an HVI design environment with a user-friendly flowchart-style interface.
Keysight’s HVI Technology uses the same programming instructions that are available in the Keysight SD1 Programming Libraries, with the difference that in a HVI those instructions are executed by the hardware modules in hard real-time, not by the computer. The programming instructions for the M31/M33XXA Digitizers are described next.
