4.13 Performing a Self-Alignment
When strong temperature changes occur in the environment of the
R&S FPL1000, or after updating the firmware, you have to perform a self-align-
ment to align the data to a reference source.
During self-alignment, do not connect a signal to the RF input connector. Running
a self-alignment with a signal connected to the RF input can lead to false mea-
surement results.
Performing a self-alignment
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 oper-
ating temperature has not yet been reached.
Depending on the installation settings, an automatic self-alignment is performed
each time the instrument is switched on. A dialog is displayed indicating how
much warm-up time is still required before self-alignment can be performed.
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 mes-
sage is displayed.
To display the alignment results again later
●
Press the [SETUP] key.

Press the "Alignment" softkey.
