Export Data


PLTS can export data for use with modeling and simulation tools. Export Data saves trace data for the Active View (Window).

Quickly Save Trace Data

All of the traces in a plot can be saved to a *.csv file.

  1. Right-click on any plot window, then select Save Traces As.

  2. Navigate to a folder and enter a file name.

The data is saved to a *.csv file which can be opened by a spreadsheet application or text editor.

 

Beginning with PLTS 2018, 64 ports are supported.

How to Export Data

Click File, then Export

Export Data dialog box help

Important Note about Importing Data into PLTS:

  • PLTS will NOT import files with Power Sweep data. Attempting to import files with Power Sweep data could cause PLTS to close without notice.

Note: Complete this dialog box in numeric sequence from top to bottom. This is necessary because the selections that are available in each field depends on previous selections. For example, if you select Frequency domain data, then the selections for format are different than if you selected Time domain data.

  1. Export Data from File - Select the file that contains the data to be exported.

  2. Select Data Domain to Export  Click to learn more:
  1. Select File Type - Dependent on #1. Data Domain

  2. Format of Data to Export - Dependent on #1. Data Domain

  3. DUT Configuration  View the current DUT configuration or click Change to launch the DUT configuration dialog.

  4. Select Data to Export - Dependent on #2. File Type.

  5. Independent Units - Dependent on #1. Data Domain

  6. Limit Data Range to Output

    • All - Export All of the selected data

    • Subset  The following settings define the subset. Some settings may require you to first check Interpolate

      • Start  Lowest frequency or time of the data to export.

      • Stop  Highest frequency or time of the data to export.

      • Points  Number of data points measured from Start to Stop frequency.

      • Step  Frequency or time range between each data point; available ONLY with Linear Spacing.

      • Spacing  Data points are spaced Linear mode (default), Logarithmic, points per Decade (10x), or points per Octave (2x).

    • Interpolate  May be checked automatically by PLTS if a subset setting is made that requires Interpolation. Interpolated data is not as accurate as measured data.

      • Checked - Subset settings have been changed that require the exported data to be interpolated.

      • Clear -  Exported Data is NOT interpolated. When Linear Spacing is selected, PLTS will change Subset settings that you enter to the closest measured data values which do not require interpolation. When Log, Dec, or Oct Spacing is selected, PLTS may not allow Interpolate to be cleared after changing settings. Click Reset to return to the original values.

    • Reset  Returns the Subset settings to the original values.

  1. Export Data to File - Type a full path and filename or click Browse , then navigate to a folder. The suffix is automatically appended to the filename. To see the suffix, click any other field before clicking OK. When saving more than one file, filenames are automatically generated and saved to the specified folder.

  2. Apply/Export - The Apply button saves the data and leaves the Export Data dialog open. The Export button saves the data and closes the Export Data dialog.

The following is added to the file header when De-embedding or AFR correction is applied:

Plots(1)

Exports an image - not the data - of the active window.

2. Select File Types:

  • Clipboard   Same ason Toolbar. Copies the image to the Windows clipboard. The contents of the clipboard can then be pasted into other Windows programs. This is the same as on the Toolbar.

  • .BMP, .JPG, or .TGA (Targa)  Same as on the Toolbar.Saves the image file.

3. Format of Data to Export:  Choose from several resolution choices.

Math Data (1)

Exports a math trace to the selected file type. Only available when a math formula is saved. Learn more about Math.

2. Select File Types:  Text (tab delimited), Text (comma delimited)

3. Format of Data to Export: Dependent on domain used in math formula (Frequency or Time).

4. DUT Configuration - Same for all data domains.

5. Select Math Formula to Export:  Lists the math formulas that are currently in PLTS memory.

Text Files

  • Import into spreadsheet or other text applications.

  • Import directly into most Keysight ADS applications.

  • Tab delimited or comma delimited.

  • Save some or all parameters.

  • Click Advanced to choose one file per parameter or all parameters to a single file.

The following is an example of text file header information:

Select Measurement Parameters dialog box help

This dialog box appears when Advanced is clicked with:

  • Frequency Domain and Text file or Citifile file selected, or

  • Time Domain selected.

Select some or all of the parameters to export.

Export Gated (S)Parameters  Gating data is ONLY available for export if a selected parameter is currently open in a window with start and stop gates.

When checked, if any of the selected parameters currently reside in open "gated" windows, the gated data is exported. If the selected parameter has no gating data available, the ungated data is exported.

When cleared, the ungated, calibrated data is exported.

Export All Data in One File  When checked, all of the selected parameters are saved to a single file.

When cleared, all selected parameters are saved to separate files. Each file is saved to the specified folder with the filename you entered and a parameter label appended to the name. For example, if you entered device4 as the file name, the S11 parameter file is named: device4_S11.txt.

 

Advanced Data Selection dialog box help

This dialog box appears when Touchstone, TDA, or Cadence Allegro file types are selected.

Measured Ports

Allows you to export the data with different port configuration than that in which it was measured. By default, the port assignments are identical. Change the measurement port to align with the exported port number. For example: The changes to the dialog box above results in an exported file with the following header information:

(Ports 2 and 3 are reversed)

! S12 = S13
! S13 = S12
! S21 = S31
! S22 = S33
! S23 = S32
! S24 = S34
! S31 = S21
! S32 = S23
! S33 = S22
! S34 = S24
! S42 = S43
! S43 = S42

Export Gated Parameters -  Gating data is ONLY available for export if a selected parameter is currently open in a window with start and stop gates.

When checked, if any of the selected parameters currently reside in open "gated" windows, the gated data is exported. If the selected parameter has no gating data available, the ungated data is exported.

When cleared, the ungated data is exported.

Export Smoothed Parameters - When checked, the exported file contains smoothed data only if it has already had smoothing applied. This operation does NOT perform smoothing. Learn how to apply Smoothing.

Export DC Values - When checked, the exported file contains the extrapolated DC Value. Learn more about Extrapolated DC Values.
