When saving data (setups, measurements, JPEG, and so forth) in a VNA Master with Option 7, the save location must be an external USB memory device. If a USB memory device is not connected to the instrument, then you cannot perform the save function.
You can use the following steps to change the save location while saving a file:
1. Press the Shift key, then the File (7) key.
2. Press the Save soft key.
3. Press the Change Save Location soft key.
4. Use the rotary knob or arrow keys to highlight the external USB memory device or any desired folder on that device.
5. Press the Create Folder soft key to create a new folder, if desired.
6. Press the Set Location soft key to set the highlighted folder or drive as the target location.
7. Press the Change File Type soft key to pick a different file type, if desired.
8. Use the Text Entry soft keys to enter the desired file name.
9. Press Enter to save the file.
Calibration Setup
After any user calibration, the VNA Master automatically writes the calibration file to internal memory. This is done so that when the instrument is turned Off and then back On, the user calibration data are recalled, and the calibration can be applied.
With Option 7 enabled, however, the VNA Master cannot write to internal memory. Therefore, the user calibration file is not automatically saved. With Option 7 enabled, when the instrument is turned Off and then back On, the user calibration data are not recalled, and the calibration cannot be applied. To save and recall the calibration, use the file save menu to save the setup with calibration to USB memory. Then use the file recall menu to retrieve the calibration.
