Internal Adjustments - Setup-System
The R&S SMC Signal Generator is extremely accurate thanks to the integrated procedures for
adjustments.
All internal adjustments for which no external measuring equipment is needed can be started in the
Internal Adjustments... menu. The adjustments with external measuring equipment are described in
the Service Manual (on CD ROM, supplied with the instrument).
Adjustment is recommended if the temperature range in which the instrument is operated changes, or
prior to all applications which require maximum level and frequency accuracy.
During adjustment a bar indicates the status of progress. If an error occurs, adjustment is terminated
and an error message is output in the info line.

The Internal Adjustments menu under System is opened up using the SETUP key.
