Graphical User Interface Overview : Saving and Recalling Measurements
 
Saving and Recalling Measurements
The Spectrum Master 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. Refer to File Management for other file operations such as copy, move, and directory management.
Saving a Measurement
To save a measurement or setup:
1. Press FILE > SAVE AS...
2. If desired, change the destination.
3. Enter the desired file name using the keyboard.
4. Select the type of file to save from the Save as type selection list.
5. Press SAVE to save the file.
After 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. Refer to Figure: FILE Menu for more information about QUICK SAVE.
Recalling a Measurement
You can recall a saved setup (*stp), native trace measurement (*.rsm), and a limit line (*.lim). 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:
1. Press FILE > RECALL...
2. Select the file location.
3. Select the desired file from the displayed list. You can use the file type filter to shorten the list if needed.
4. Press OPEN to recall the file.
When a trace measurement is recalled, the trace or sweep state will be set to hold. To restore active measurements, set TRACE > MODE > Active.
FILE Menu
The file menu in Figure: FILE Menu shows all possible selections. The available selections vary depending on the selected measurement and view. Refer to
FILE Menu
 
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. You can save the following:
• Setup: Saves the current instrument setup (stp file type).
• Trace: Saves the measurement point (trace) data and the current instrument setup (rsm file type).
• Trace CSV: Saves the visible trace point data in comma separated value format (csv file type). This format is useful for further analysis using other software tools.
• Limit: Saves the current limit line point data (lim file type).
• Screenshot: Saves a screenshot of the current measurement (png 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 are 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 Submenu.
BROWSE FILES: Opens File Management.
SAVE ON EVENT Submenu
SAVE ON EVENT saves the current trace data to a folder named with the current date and time (yyyymmddhhmmss) for various criteria.

LIMIT CROSSED
When enabled, measurement trace data are 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.
SWEEP END
When enabled, measurement trace data are automatically saved after the current sweep is completed. If SINGLE is selected, the first sweep will be saved and the event will be set to OFF. If CONTINUOUS is selected, each sweep will continue to be saved.

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