Internal Data Processing

Data processing sequence

Figure 6-5 outlines the sequence of data processing performed within the Agilent 4294A.
Figure 6-5 Agilent 4294A Data Processing Sequence
The following describe each of the data arrays shown in Figure 6-5.

Internal data arrays

Data array
The data array contains the results of user calibration, port extension compensation, sweep
averaging and fixture compensation performed on the measured data. Each result is stored
as a complex number (R-X). Use the following commands to read or write the data array.
• "OUTPDATA?" on page 375
• "OUTPDATAP?" on page 375
• "INPUDATA" on page 321
Memory array
The memory array contains a copy of the data array available when the "DATMEM"
command on page 285 is executed. Use the following commands to read the memory array.
Note that you cannot write any part of the memory array.
• "OUTPMEMO?" on page 385
• "OUTPMEMOP?" on page 385
