Modes

The Bus Monitor is used to record bus traffic with choices to attach a time tag to each word (Word Mode) or each wordstring (String Mode).

Using String Mode, a string includes all consecutive words on the bus (label word and data words). Filtering and Sampling are available with this mode.

Using Word Mode, each 20-bit word will be time-tagged and stored in the acquisition queue. Filtering and Sampling are not available with this mode.

The Bus Monitor mode is selected using the mxfAttributeUint64Set() function with the KMXF_A629_BM_MODE attribute key constant.
