Read and Write Measurement Data
Internal Data Flow
Data Array
The data array contains the results of the sweep averaging performed on the raw data array.
It is stored as a complex format (R-X).
Reading or writing the data array is not allowed.
Memory Array
The memory array contains the copied data array.
Reading or writing the memory array is not allowed.
Data Trace Array
The data trace array contains the number of measurement points of results obtained by
measurement parameter conversion on the data array. For a scalar trace, results are stored
in the real format, and for a complex trace, results are in the complex format. In addition, if
data operations are performed between the data and memory trace arrays, the data trace
array contains the results. Use the following GPIB command to read the data trace array.
• CALC{1-5}:DATA? on page 293
Writing the data trace array is not allowed.
Memory Trace Array
The memory trace array contains the number of measurement points of results obtained by
measurement parameter conversion on the memory array. For a scalar trace, results are
stored in the real format, and for a complex trace, results are in the complex format. In
addition, when the equivalent circuit analysis function is used, the memory trace array
contains the simulation results of frequency characteristics. Use the following GPIB
command to read the memory trace array.
• CALC{1-5}:DATA? on page 293
Writing the memory trace array is not allowed.
Stimulus Array
The stimulus array contains stimulus values of all measurement points. Use the following
GPIB command to read the stimulus array.
• SWE:STIM{1-4}? on page 512
Writing the stimulus array is not allowed.
DC Bias Level Monitor Array
The dc bias level monitor array contains dc bias voltage or current level monitor values in
the real format. Use the following GPIB command to read the dc bias level monitor array.
• CALC:DATA:MON? on page 292
Writing the dc bias level monitor array is not allowed.
