Compensation data array
The compensation data array contains open, short and load measurement data used for
calculation of the fixture compensation coefficient. These data are stored as complex
numbers. Three different types of arrays are available to choose from depending on the
type of measurement data (open, short, or load data).
Number
Use the following commands to read or write the compensation data array.
• "OUTPCOMC{1-3}?" on page 374
• "INPUCOMC{1-3}" on page 321
Sweep parameter array
The sweep parameter array contains sweep parameters for all measurement points. Use the
following commands to read the sweep parameter array. Note that you cannot write any
part of the sweep parameter array.
• "OUTPSWPRM?" on page 394
• "OUTPSWPRMP?" on page 394
Saving array as file
You can save an internal data array as a file. This feature saves time and effort because you
can recall the file later and avoid the need to again perform the arithmetic. Use the
following commands to save or recall an internal data array. See Chapter 8 ,
"Saving/Recalling a Measurement Result/Measurement Setup," for more information.
• "SAVCAL" on page 416
• "SAVDAT" on page 417
• "SAVDTRC" on page 420
• "SAVMEM" on page 420
• "SAVMTRC" on page 421
• "SAVDASC" on page 416
• "SAVDDAT" on page 417
• "RECD" on page 408
NOTE You can save an internal data array in the touchstone format by "SAVDS1P" on page 418.
But you cannot recall the file.
