If you start a self-alignment remotely and then select the "Local" softkey while the
alignment is still running, the instrument only returns to the manual operation state
after the alignment is completed.
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 measurement
results.
Alignment results
The alignment results are displayed and contain the following information:
●
Date and time of last correction data record
●
Overall results of correction data record
●
List of found correction values according to function/module
The results are classified as follows:
PASSED Calibration successful without any restrictions
CHECK Deviation of correction value larger than expected, correction could however be per-
formed
FAILED Deviations of correction value too large, no correction was possible. The found cor-
rection data is not applicable.
The results are available until the next self-alignment process is started or the instru-
ment is switched off.
Temperature check
During self-alignment, the instrument's frontend temperature is measured (as soon as
the instrument has warmed up completely). This temperature is used as a reference for
a continuous temperature check during operation. If the current temperature deviates
from the stored self-alignment temperature by a certain degree, a warning is displayed
in the status bar. The warning indicates the resulting deviation in the measured power
levels. A status bit in the STATUs:QUEStionable:TEMPerature register indicates a
possible deviation. The current temperature of the frontend can be queried using a
remote command (see SOURce<si>:TEMPerature:FRONtend on page 486).
Touchscreen alignment
When the device is delivered, the touchscreen is initially calibrated. However, to ensure
that the touchscreen responds to the finger contact correctly, a touchscreen alignment
is required.
Alignment of the touchscreen is useful:
●
At first use
●
After an image update or after exchanging a hard disk
●
If you notice that touching a specific point on the screen does not achieve the cor-
rect response
