When to perform adjustments?
We recommend that you perform internal adjustments in the following cases:
●
Before starting any application, that requires a maximum of level and frequency
accuracy
●
When a long period of time has passed since the last adjustments
●
If the ambient temperature of the instrument significantly differs from the one of the
last adjustments
Additional Information to the Adjustments
During adjustments, a progress indicator shows the status of the process. If any error
occurs, the process aborts and an error message appears in the info line.
The extent of the adjustments depends on the installed options.
14.3.1 Date and Time Settings
The R&S SMA100B uses an internal real-time clock to determine the date and time. It
adjusts the time and date to the timezone of your location automatically, by providing a
selection list of continents and cities.
The instrument records the time whenever you create or modify files on your instru-
ment or you use timed licenses. By default, the instrument is set to the UTC timezone,
but you can select the timezone according to your location.
Moreover, the instrument supports NTP protocol for synchronizing all connected instru-
ments and computer systems to minimize time delays in the network.

► Select "System Config > Setup > Maintenance > Date / Time".
