I
Preset State and Memory Allocation
Following are some examples:
state, saving instrument state only:
Size = 0 + 140 + 9580 = 9720
l
Using 201 points, with on channel 1, channel 2
Size = 0 + 140 + 9580 + (6 x 201) = 10,926
l
Using 201 points, with on channel 1, channel 2 off, and saving
both the instrument state and data:
Size = 0 + 140 + 9580 + (6 x 201) + 178 + (6 x 201) 12,310
l
Same as above, but after performing a transmission calibration and saving
the calibration:
Size = 0 + 140 + 9580 + (6 x 201) + 178 + (6 x 201) + 246 + (4 x
6 x 201) = 17,380

NOTE
Most disks use a sector size of 256 or 512 bytes, so there will usually be a small amount of wasted
space on the disk.
general, memory usage increases with number of points and complexity of
information saved.
Reflection calibrations use more memory than transmission calibrations
because they use more error arrays.
When multiple types of information are saved together, the total can be less
than indicated above because redundant internal information is eliminated.
