R&S FSP Instrument Functions
Basic Settings
Selftest
SELFTEST The SELFTEST softkey initiates the selftest of the instrument modules.
With this function the instrument is capable of identifying a defective module in case
of failure.
During the selftest a message box appears in which the current test and its result is
shown. The test sequence can be aborted by pressing ENTER ABORT.
All modules are checked consecutively and the test result (selftest PASSED or
FAILED) is output in the message box.

associated value range and the corresponding test results are indicated.
Remote command:

The realignment should be carried out by qualified personnel since the changes
considerably influence the measurement accuracy of the instrument. This is the
reason why the softkeys

CHANGES can only be accessed after entering a password.
