Section 6: Data Store Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Data store programming example
Table 6-2 summarizes the commands for basic data store operation. These commands set up the
Model 6482 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 F for a complete program listing, which also shows how to determine when
the buffer is full by reading the appropriate status register bits. See Section 13 for details
on the status structure.
