Internal Adjustments

The R&S SMB is extremely accurate due to the integrated adjustment procedures,
which you can execute directly on the instrument.
Self-calibration routines that do require additional (external) measurement equipment
are either described in the Service Manual of the instrument, or they require to be per-
formed by a Rohde & Schwarz service center.
Risk of invalid adjustment
In order to achieve correct adjustment of the instrument, make sure that the instrument
is warm before performing adjustments. The warm-up time is 30 minutes.
When to perform adjustments?
It is recommended to perform internal adjustments prior to any application that requires
a maximum of level and frequency accuracy, especially when a long period of time has
passed or if the ambient temperature of the instrument significantly differs from the one
of the last adjustment.
