Saving Measurement Results
Instrument states combined with measurements results can only be saved to disk. Files that contain
data-only, and the various save options available under the
key, are also only
valid for disk saves.
The analyzer stores data in arrays along the processing flow of numerical data, from IF detection to display.
These arrays are points in the flow path where data is accessible, usually via GPIB. You can choose from
three different arrays which vary in modification flexibility when they are recalled.
•raw data
• data (raw data with error-correction applied) if correction is on; otherwise, raw data
• format (data processed to the display format)
If you choose to save the raw data array, you will have the most flexibility in modifying the recalled
measurement (including the ability to view all four S-parameters). This is because the raw data array has the
least amount of processing associated with it. Conversely, if you choose to save the format array, your
modification of the recalled measurement will be limited by all the processes that are associated with that
measurement result. However, the format array is appropriate if you want to retrieve data traces that look
like the currently displayed data.
You can also save data-only. This is saved to disk with default file names
DATA00D1 to DATA31D1 for channel 1
DATA00D2 to DATA31D2 for channel 2
DATA00D3 to DATA31D3 for channel 3
DATA00D4 to DATA31D4 for channel 4
However, these files are not instrument states and cannot be recalled.
