When you save a reference, it is automatically appended to the
measurement.
To save and load reference and measurement files
1 Press the File softkey.
2 Using the arrow keys, select one of the following options:
– Save Reference – Saves the current measurement as a refer-
ence file for use as a reference against live measurements.
NOTE
Since a reference file is essentially an average of the data obtained
from four sequential traces, at least four sequential traces must
occur before you can save a file to be used as a reference file. If
you attempt to save a reference file before enough data has been
collected, the Not Enough Data error message is displayed.
NOTE
The maximum file name length is twelve (12) characters.
– Save File – Saves the current measurement as a static
measurement file.
NOTE
To assure exact measurement recording of current display, always
pause (Shift, 8) measurement updates before saving.
– Load Reference – Proceeds to a work folder associated with
sweep reference files. Select a reference file from the work
folder. If the selected file is not compatible with the current
received sweep plan, a message is displayed. This feature
enables you to view the difference between the live data and
the data stored in the file. When you select a reference file, the
file name is displayed in the subtitle bar in place of 'REF:
NONE'.
