The Frequency Blanking submenu is displayed only when Option 7, Secure Data Operation, is installed on the Spectrum Master. When Frequency Blanking is turned On, all frequency values that are displayed on the screen and menu buttons are replaced with ##.#####. This security measure allows the use of the instrument without sensitive frequency information being displayed on the screen.

Note that saved measurements retain the frequency information, which may then be viewed on a PC, or recalled after frequency blanking is turned off.

Setting Frequency Blanking to Off will preset the instrument settings and frequencies to the factory default settings (the current frequency settings will not be saved or displayed on the instrument).
