Saving and Recalling Measurements
The Field Master Series 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 File Management section of the product’s user guide.
Saving a Measurement
To save a measurement or setup, refer to Figure: File Save Dialog:
1. Select FILE > SAVE AS...

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.

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 File: Saves the current instrument setup file (stp file type).
• Trace File: Saves the measurement (trace or point data) and the current instrument setup (fmiasp file type).
• Trace CSV File: Saves the visible trace point or map point measurement data 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.
• Limit File: 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 fmiasp, and png file types).
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. This feature is not available in the 5GNR/LTE analyzer.
BROWSE FILES
Opens the file management screen. Refer to the product’s user guide for more information.

INTERVAL
A save will occur periodically. Set the desired period by entering the time.
