Comments • Executable when initiated: No
• Coupled command: Yes. This command is coupled to the TRIGger subsystem.
• If the data in memory is in multiple segments, then there will be a small delay
(630 µs) between segments while the CPU switches the memory address to point
to the next segment. It is possible to determine when data is available again by
monitoring bit 1 of the A24 arm status register (base + 43
16
). This bit goes high
when the data is again ready for transfer. See "VME Bus Data Transfers" in
Chapter 3 for additional information.

Example Reading both channels out to the VME (VXI data transfer) bus
TRIG:SOUR VME Set up trigger system for VME transfer
VINS:VME GEN Set GENerate mode
VINS:VME:FEED " MEM:BOTH32 " Set data source to be both channels
INIT Begin the transfer
[:CONFigure]:VME:MEMory:INITiate
VINStrument[:CONFigure]:VME:MEMory:INITiate configures the HP
E1429 for data transfer over the VME bus when the data register in A24 address
space is read. The configuration is done automatically if the
INITiate:IMMediate command is executed while
VINStrument:CONFigure:VME:MODE is GENerate and any of the
"MEMory:xxx" settings is the selection for
VINStrument[:CONFigure]:VME:MEMory:INITiate
