Performing a Self-Alignment and a Selftest
During instrument start, the installed hardware is checked against the current firmware
version to ensure the hardware is supported. If not, an error message is displayed
("WRONG_FW") and you are asked to update the firmware. Until the firmware version
is updated, self-alignment fails.
(For details refer to the R&S
FSW User Manual).
Furthermore, it may be necessary to align the data to a reference source by performing
a self-alignment when strong temperature changes occur.
Operating temperature
Before performing this functional test, make sure that the instrument has reached its
operating temperature (for details, refer to the data sheet).
A message in the status bar ("Instrument warming up...") indicates that the operating
temperature has not yet been reached.
Performing a self-alignment
1. Press the SETUP key.
2. Press the "Alignment" softkey.
3. Select the "Start Self-Alignment" button in the "Alignment" dialog box.
Once the system correction values have been calculated successfully, a message
is displayed.

Performing a selftest
The selftest does not need to be repeated every time the instrument is switched on. It
is only necessary when instrument malfunction is suspected.
