Recall Measurement
This function brings up a selection box that allows recall of a previously stored
measurement trace. Use the rotary knob or the
Up/Down arrow keys to highlight
the saved measurement trace, and press
Enter, the rotary knob, or the Recall soft
key to select. Press the
Esc key to cancel the recall.
If the setup of the recalled trace is functionally the same as the current sweep
setup, then the recalled trace is displayed as a green trace. The active sweep is
then displayed in yellow. If the setup of the recalled trace is different from the
current sweep setup, then the recalled trace is displayed alone, this time in
yellow, along with the message
Press ESC to clear Recall Trace.
Upon pressing the
Esc key, a dialog box appears with the message Press Escape to
keep old settings, or Enter to use Recalled Values
. If the Esc key is pressed, then the
recalled trace disappears, and only the active sweep is displayed. The system
sweep settings (that were in effect before the trace was recalled) are restored.
Pressing
Enter loads the sweep settings that are associated with the recalled
trace, and the VNA Master begins making measurements using those sweep
settings.

Directory Management
Brings up the Directory Management soft menu. For a description of the
directory management menu and soft keys, see “ Directory Management” on
page 3-32.
Back
Returns to the previous menu.
Delete
Brings up a selection box that shows all stored setups and traces in the currently
selected location (See Directory Management on page 4-28.) The list shows the setup
and measurement names, the type (stp for a saved setup, spa for a saved trace, jpg for a
JPEG file) and the date and time the information was saved. Use the rotary knob or the
Up/Down arrow keys to highlight the file to be deleted, and press Enter, or the Delete soft
key to delete. Press the
Esc key to cancel the operation. Note that there is no
mechanism to retrieve deleted files.
Delete Selected File
Use the up and down arrow buttons or the rotary knob to select the file that is to
be deleted. Press
Enter to confirm that you want to delete the file or Esc to exit
without deleting.
Delete ALL Measurements
Deletes all measurements of the current mode in the currently selected storage
location. The memory from which measurements will be deleted is set in the
Directory Management menu and is the Current Location.
Note
Recalling the sweep settings of the recalled trace destroys the current calibration
information, and the VNA Master needs to be calibrated at the recalled settings
before valid measurements can be made.
