VINStrument[:CONFigure]:LBUS[:MODE]

This command results in an error if VINStrument:CONFigure:LBUS:FEED is not one of the "MEMory" choices (i.e. "MEMory:BOTH", etc.).

If the data in memory is in multiple segments (ARM:STARt:COUNt > 1 and SENSe:SWEep:POINts:DELay < 0), then there will be a small time delay between transfer of each segment while the CPU switches the memory address to point to the next segment.

This command has no query form.

[:CONFigure]:LBUS[:MODE]

VINStrument[:CONFigure]:LBUS[:MODE] <mode > selects the operating mode for the VXI Local bus. The available modes are:

APPend: Local bus data is received from the left, and passed on to the right until an end of frame is detected. When end of frame is received from the left side, all data from this module is appended, followed by an end of block flag and a new end of frame flag. After sending the end of frame flag, the module enters the paused state. This mode requires a module to the left that is in GENerate mode. The mode is not active until either an INITiate command or a VINStrument:LBUS:MEMory:INITiate command is sent.

GENerate: Local bus data originates in this module and is passed to the right, followed by an end of frame flag. The mode is not active until either an INITiate command or a VINStrument:LBUS:MEMory:INITiate command is sent.

INSert: Local bus data is inserted onto the bus from this module. The module will place its data out onto the Local bus with an end of block flag at the end and no end of frame flag. The module will then pass through (pipeline) any data it receives from the left, and will enter the paused state when an end of frame flag is received from the left. This mode requires at least one module to the left
