Saving Measurement Results - Agilent Technologies 8719D User Manual

Saving Measurement Results

Instrument states combined with measurements results can only be saved to disk. Files that
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 HP-IB. You can choose from three different arrays which vary in modification flexibility
when they are recalled.
raw data
n
data (raw data with error-correction applied)
n
format (data processed to the display format)
n
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 filenames DATAOODl to
channel 3, and DATAOOD4 to DATA31D4 for channel 4. However, these files are not instrument
states and cannot be recalled.
