[:CONFigure]:VME:FEED

VINStrument[:CONFigure]:VME:FEED <source > selects which data source will feed the VME (VXI data transfer) bus. The bus is driven by reading the data register, offset 12 (0C16) in A24 address space. Sources beginning with "MEMory: " are the post measurement modes, sources beginning with "CONVerter: " are the real time modes. The possible sources are:

"MEMory:CHANnel1" : Channel 1 memory is the data source for the VME bus. One 16-bit reading is returned.

"MEMory:CHANnel2" : Channel 2 memory is the data source for the VME bus. One 16-bit reading is returned.

"MEMory:BOTH" : Both channels of memory are the data source for the VME bus. In this mode, channel 1 will be output the first time the data register is accessed, channel 2 is output the second time the data register is accessed. One 16-bit reading is returned with each access.

"MEMory:BOTH32" : Both channels of memory are the data source for the VME bus. In this mode, accessing the data register returns a 32-bit number where the high order 16 bits are the channel 2 reading and the low order 16 bits are the channel 1 reading.

"CONVerter:CHANnel1" : The channel 1 A/D converter is the data source for the VME bus. One 16-bit reading is returned.

"CONVerter:CHANnel2" : The channel 2 A/D converter is the data source for the VME bus. One 16-bit reading is returned.

"CONVerter:BOTH" : Accessing the data register triggers both A/D converters at the same time, and one 16-bit reading (channel 1) is returned. Accessing the data register a second time returns the second 16-bit reading (channel 2), but does not trigger the A/Ds.

"CONVerter:BOTH32" : Accessing the data register triggers both A/D converters at the same time, and one 32-bit number is returned. The high order 16 bits are the channel 2 reading, and the low order 16 bits are the channel 1 reading.
