When option R&S

FSV3-K33 (security write protection) is enabled, the self align-

ment data cannot be written to the SSD or CFAST card.
In this case, two solutions are possible:
–

Run a self alignment always after powering on the instrument. The self align-
ment data will not be stored on the instrument permanently.

–

Temporarily disable the R&S

FSV3-K33, security write protection, as described

in

Securing Self Alignment Data when Secur-

ity Write Protection is Enabled

When the security write protection (R&S

FSV3-K33) is enabled, the R&S

FSV/A redi-

rects the self alignment data to the volatile memory (SDRAM). The SDRAM memory
loses its data when you power off the instrument.

Note that the instrument has sufficient warm-up time before you perform the self-align-
ment.

To make sure, that no self alignment data get lost, keep closely to the instructions:

1. Deactivate the write protection of the SSD or the CFAST memory card to allow the

alignment data to be saved on the card. The write protection is disabled by deacti-
vating the secure user mode (requires administrator login):

Note:

 If you do not remove the write protection before, the self alignment data get

lost when you power off the instrument. As a result, the measurement values can
deviate later on.

a) Select [SETUP] > "System Configuration".
b) In the "Config" tab, select "Secure User Mode > Off".

This change does not take effect until you have restarted the instrument.

c) Reboot the R&S

FSV/A.

2. Perform the self-alignment:

a) Select [SETUP].
b) Select the "Alignment" softkey.
c) Select "Start Self Alignment" button.

Once the system correction values have been calculated successfully, the
R&S

FSV/A prompts a message.

The R&S

FSV/A saves the self-alignment data on the SSD or the CFAST memory

card .

To reactivate the secure user mode:

1. Select [SETUP] > "System Configuration".
