Determining Memory Requirements

Table 8-5 shows the memory requirements of calibration arrays and memory trace arrays
to help you approximate memory requirements. For example, add the following memory
requirements:
• a full 2-port calibration with 801 points (58 k)
• the memory trace array (4.9 k)
• the instrument state (6 k)
The total memory requirement is 68.9 kbytes. There is sufficient memory to store
29 calibrations of this type. However, the same calibration performed with 1601 points and
2 channels uncoupled would require 255 k bytes:
• a full 2-port calibration with 1601 points, two channels, uncoupled (230 k)
• the memory trace array (19 k)
• the instrument state (6 k)
Only 2 of these calibrations could reside in memory before the available memory would be
depleted.
