Example 4, 8510 3-Term Frequency List Cal Set File
Example 4 shows how CITIfile may be used to store instrument setup information. In the
case of an 8510 Cal Set, a limited instrument state is needed in order to return the
instrument to the same state that it was in when the calibration was done. Three arrays of
error correction data are defined by using three DATA statements. Some instruments
require these arrays to be in the proper order, from E1 to E3. In general, CITIfile
implementations should strive to handle data arrays that are arranged in any order.
Example:
