Description:
This command returns a block of floating point data from the E1437 that has been
scaled to be in volts. The number of samples designated to be read must account for
variations in blocksize, data type and resolution.
Data is returned as an ASCII string with points separated by commas. You can read
up to 4 complex points or 8 real points per read command.
This command can only read data from the VME backplane register. The data port
of the E1437 must be set to VME by the DATA:PORT command for this command to
be effective. To read data using the local bus in an E1485 environment, see the
documentation for local bus data transfers in the E1485 documentation package.
