How to set Frequency Blanking

Using Hardkey/SoftTab/Softkey

Press System > Main > Security....

Security Setting Dialog Box Help

Notes:

To learn how to erase memory before moving VNA out of a secure area, see http://na.tm.Keysight.com/pna/security.html.
An ECal Data Wipe Utility destroys all user data per US DoD 5220.22-M. Learn more at http://na.tm.Keysight.com/pna/apps/applications.htm

Security Levels

None - All frequency information is displayed.

Low - No frequency information is displayed. Return to this dialog box to re-enable display of frequencies.

Frequency information is blanked from the following:

Display annotatio
Calibration properties
All tables
All toolbars
All printouts
External sources - See Also: Preference to Deactivate External Devices on Preset

Note: Frequency Blanking is fully supported ONLY on Keysight MXG sources with option 006. On MXG models without option 006 and all PSG models, the window state is turned OFF. When the “local” button is clicked on the source, then frequency is re-displayed.

High - No frequency information is displayed. Only Preset or recall of instrument state can re-enable display of frequencies.

Low security level settings PLUS:

GPIB console is inactive.

Extra - Frequency information is not displayed and will not be saved to ASCII file types. Only Preset or recall of instrument state can re-enable display of frequencies.

High security level settings PLUS:

All ASCII data saving capability (.snp, .prn, .cti) is saved without frequency information. The X-axis information is replaced with data point numbers.
Mixer setup files (*.mxr) can NOT be saved.

For ALL security levels:`

Frequency information is NOT blanked from the following:

Service Adjustment Programs.
SCPI programs.

Instrument State and Cal Sets

The security level is always saved and recalled with an instrument state. However, the instrument state may contain a Cal Set or link to a Cal Set. Learn more. This may influence the security level when the instrument state is recalled.

When a new Cal Set is created at the end of a calibration, the current system security level is stored with it.
The only way to change an existing Cal Set’s security level is by writing a new calibration into the Cal Set.
When later applied to a channel, if the Cal Set has a higher security level than the current system security level, the system security level will become upgraded to that of the Cal Set.
When saving an instrument state to either a *.csa or *.cst file, the security levels of the system and Cal Set are saved separately. When recalled, the higher security level of the two is applied.
To view the security level of a Cal Set, see Cal Set Properties.

Re-displaying frequency information

When in Low security level, do any of the following:
- Revisit this dialog box and select None.
- Perform an instrument preset.
- Recall an Instrument State/Cal Set with security level of None.
When in High or Extra security level, do any of the following:
- Perform an instrument preset.
- Recall an Instrument State/Cal Set with security level of None.
