Save Setup
Opens a dialog box to name and save the current operating settings, allowing
them to be recalled later to return the instrument to the state it was in at the
time the setup was saved. The saved setup can be named using the keypad to
select numbers, the rotary knob to highlight a number or character and pressing
the knob to select, or by selecting the soft key for each letter. Use the Shift key to
select an upper case letter. Use the
Left/ Right directional arrows to move the
cursor position. Press Enter to save the setup.
Save Measurement
Initiates a dialog box to name and save measurement data for all three current
trace locations: A, B, and C. The saved measurement can be named using the
keypad to select numbers, the rotary knob to highlight a number or character
and pressing the knob to select, or by selecting the soft key for each letter. Use
the Shift key to select an upper case letter. Use the Left/Right directional arrows
to move the cursor position. Press Enter to save the measurement trace.
Measurements are saved in a directory called /usr on the Compact Flash memory
module or the USB Flash Drive.
Save Limit Line
Pressing this soft key opens a dialog box to save the current upper and lower
limit lines. You can name the saved limit line yourself or accept the name that is
suggested by the instrument (which is based on a previously saved name). If you
decide not to save the limit line, press
Esc to stop the save dialog.
Save On Event…
The instrument can be configured to automatically save a measurement if a
selected condition is satisfied. As measurements are saved, an on-screen message
indicates approximately how many more files can be saved. Over 3000 spectrum
analyzer measurements can be saved before the internal memory is full. The
number of measurements that can be stored in the Compact Flash memory
depends on the size of the memory module. When measurements are saved, they
are saved into subdirectories that are automatically created in the /usr
subdirectory. The names are based on the date and time. Each subdirectory can
contain a maximum of 1000 measurements.
… Crossing Limit On/Off
When Crossing Limit is On, and an upper or lower limit line is set, if any
point in a measurement exceeds either the upper or lower limit line, the

press the Right directional arrow and add the changes. To create a completely
new name, use the keypad, the rotary knob, or select the soft key for each letter.
