Security
The security concept of the R&S SMA100B helps you to protect your instrument
against uncontrolled access and changes. All provided security services require that
you enter the security password.
Provided security services are:
●
General security parameters, such as:
– USB storage that secures controlled access to the mass memory of the instru-
ment
– Volatile mode that prevents information to be written to the internal memory
permanently.
– Sanitizing that prevents the instrument from leaving a secure environment with
stored user information.
– Annotation frequency and amplitude prevent reading the display.
– Secure Update Policy check that verifies the integrity and origin of the firm-
ware package to be installed.
To access the settings of these topics, see Setting security parameters >
"Secure Update Policy" on page 364.
●
Password management secures controlled user access to the instrument
With the two-step password concept, you can assign a user-defined password for
the operating system, and a security password for accessing the mass storage of
the instrument.
