Models 2500 and 2502 User’s Manual Data Store 8-7
Data store programming example
Table 8-2 summarizes the commands for basic data store operation. These commands set
up the Model 2500 as follows:
• Number of points: 10
•Trigger count: 10
• Data store feed: channel 1 readings only
• Acquired data: all buffer readings, mean (average), and standard deviation.
NOTE See Appendix H for a complete program listing which also shows how to deter-
mine when the buffer is full by reading the appropriate status register bits. See
Section 14 for details on the status structure.
