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 + 4316). This bit goes high when the data is again ready for transfer. See "VME Bus Data Transfers" in Chapter 3 for additional information.

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
