File Types

• *.dsta - PLTS State files. Contains all of the settings that are in your current PLTS setup. You can then recall the setup at a later time. Learn more about state files (below).
• *.dut - Contains corrected measurement data, computed Time Domain data, computed Balanced Mode data, and information about the measurement and calibration.
• *.cal - Contains correction data and measurement setup data that was saved after performing a calibration. Does NOT contain measurement data. When recalling a .cal file, the instrument is configured to make a measurement.
• *.tdr - Contains correction data and measurement setup data that was saved after performing a TDR calibration.  Does NOT contain measurement data. When recalling a .cal file, the instrument is configured to make a measurement.

File Types by Operation

Adapters - *.txs files used in Adapter Characterization and Reference Plane 2-port De-embed

Calibration:

• *.cal files from a competed VNA 'legacy' calibration

• *.tdr files from a completed TDR calibration

• *.wzd files from the TRL Calibration Wizard

• *.mkt files from Differential Crosstalk TRL Cal Kits

• *.xml files from criteria for Continuity Check

Measurement Data:

• *.DUT files from Open / Save

• Many file types for Add to Batched File Converter and Batched Ref Plane Adj.

Exported Data:

• Many file types from Export Data.

De-embedding Data - Many file types for all Reference Plane De-embedding paths.

Digital Patterns - Many file types that have been designed or imported for Eye Diagrams.

Math Formulas - *.fml files from Load/Save Math formulas

State Files (*.dsta)

State files can be used the same way that state files are used in instruments such as the PNA. Save the current PLTS setup, and then later recall the state file to save time making these same settings in the future.

The following settings are NOT saved to a *.dsta file.

• RLCG

• Gating

• Raw Cal Data and Error Terms

Save / Save As

Select File,Save to overwrite the current measurement or calibration data. New data or imported data may be saved.

Select File,Save As  to save the current measurement or calibration data as a new file.

Until measurement data is saved, the plot window title bar is labeled PLTS along with the analysis type of the plot window and the sequential plow window number.

Once the data is saved, the PLTS label is replaced with the name of the saved file.

Only one unsaved plot window may be open at a time. If you have one unsaved plot window, you must either save the data or delete the window before you can open another plot window with unsaved data.

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

Open

To Open a previously saved *.dut file

Click File then Open

Multiple files can be opened simultaneously. The limit to the number of windows that can be displayed depends on the number of plots that are viewed.

Recent Files

Open any of the four most recently accessed files by clicking the name of the file from the list (highlighted below in yellow).

Only the four most recently-accessed files are displayed.
