Saving and Recalling Measurements
The instrument can save measurement setups, native trace and CSV trace data, limit line setups, and screenshots. You can recall setup, native trace, and limit line files. For other file operations such as copy, move, and directory management, refer to the product’s user guide for more information on file management.
Saving a Measurement
To save a measurement or setup, refer to Figure: File Save Dialog:
1. Select FILE > SAVE AS...
2. If desired, press the save location to change the destination.
3. Enter the desired file name using the touchscreen keyboard.
4. Select the type of file to save from the selection list.
5. Select SAVE to save the file.
File Save Dialog
Once a file has been saved, the QUICK SAVE feature can be used to quickly save the same type of file with an incrementing number appended to the end of the original file name.
Recalling a Measurement
You can recall a saved setup, native trace measurement, and a limit line. When recalling a setup, the instrument setup and operating state will be restored as it was when the setup was saved. When recalling a trace measurement, the instrument setup and on-screen measurement data will be restored as it was when the trace data was saved.
To recall a measurement or setup, refer to Figure: File Open Dialog:
1. Select FILE > RECALL...
2. Select the file location.
3. Use the file type filter to shorten the list if needed.
4. Select the desired file from the displayed list.
5. Select OPEN to recall the file.

When a measurement is recalled, the trace or sweep state will be set to hold. To restore active measurements, disable SWEEP > HOLD and/or set TRACE > MODE > Active.

QUICK SAVE
saves a setup file immediately with the name shown in the button. The number in the name is incremented automatically so that the new name is ready for the next setup file to be saved.
SAVE AS
Opens the Save dialog to manually enter a file location, enter a file name, and to set the file type to be saved. Depending on the selected measurement, you can save the following:
• Setup: Saves the current instrument setup (stp file type).
• Trace: Saves the measurement (trace or point data) and the current instrument setup (fmspa file type).
• CSV: Saves the visible trace point or map point measurement data (Option 431, Coverage Mapping) in comma separated value format (csv file type). This format is useful for further analysis using other software tools. Note that the saved map point data is cumulative of all data points on the map or measurement data since the map points were last cleared.
• KML: Saves measurement data in Keyhole Markup Language format, including the instrument model number, installed options, sample data with GNSS (GPS) coordinates, if GNSS (GPS) is installed (Option 431, Coverage Mapping only (Indoor Map)). Note that the saved data is cumulative of all data points on the map or measurements since the map points were last cleared.
• Limit: Saves the current limit line point data (lim file type).
• Screenshot: Saves a screenshot of the current measurement (png file type).
• Trace + Screenshot: Saves both the current measurement and screenshot files (both fmspa and png file types).
• KML: Saves coverage mapping data points in Keyhole Markup Language format (kml file type).
RECALL
Opens the Recall File dialog to retrieve a file from a desired location. Only supported files will be displayed depending on the currently set measurement. When trace data is recalled, the instrument will change the settings to match the settings of the saved trace. The data will be recalled to the appropriate trace. That trace will be in a Hold mode. To exit the recalled data, simply change the trace mode back to Active.
SAVE ON EVENT: Opens the SAVE ON EVENT Menu.
BROWSE FILES
Opens File Management screen. For more information refer to the product’s user guide.

Save on event saves the current trace data to a folder named with the current date and time (yyyymmddhhmmss).
LIMIT CROSSED
When enabled, measurement trace data is automatically saved when the trace crosses a limit line that has been specified in the LIMIT menu. If SINGLE is selected, the first event will be saved and the event will be set to off. If CONTINUOUS is selected, each event will continue to be saved until the user turns it off or the memory is full.
SWEEP END
When enabled, measurement trace data is automatically saved after the current sweep is completed. If SINGLE is selected, the first sweep will be saved and the event will be turned off. If CONTINUOUS is selected, each sweep will continue to be saved until the user turns it off or the memory is full.
INTERVAL
A save will occur periodically. Set the desired period by entering the time.
