7. Use INITiate:IMMediate to activate the rightmost (INSerter)
digitizer.
8. Beginning with the leftmost (GENerator) digitizer, abort each
digitizer before using the Local bus again.
Example Program This program demonstrates how to use multiple digitizers to transfer
readings, interleaved, to an HP E1488 memory card (consumer). The
program takes 10 readings on both channels of two digitizers. Therefore, 10
frames of data (40 readings) are sent to the memory card. The example
follows the programming procedure listed above.
