Table 6-2: Status bar information - color coding
Color Type Description
Red Error An error occurred at the start or during a measurement, e.g. due to missing
data or wrong settings, so that the measurement cannot be started or com-
pleted correctly.
Orange Warning An irregular situation occurred during measurement, e.g. the settings no lon-
ger match the displayed results, or the connection to an external device was
interrupted temporarily.
Gray Information Information on the status of individual processing steps.
No color No errors No message displayed - normal operation.
Green Measurement
successful
Some applications visualize that the measurement was successful by show-
ing a message.
If any error information is available for a channel, an exclamation mark is displayed
next to the channel name ( ). This is particularly useful when the MultiView tab is dis-
played, as the status bar in the MultiView tab always displays the information for the
currently selected measurement only.
Furthermore, a status bit is set in the STATus:QUEStionable:EXTended:INFO reg-
ister for the application concerned. Messages of a specific type can be queried using
the SYSTem:ERRor:EXTended? command. For more information, see the R&S ESW
User Manual.
When you select the error message bar or status message bar, the R&S ESW shows a
list of all current errors or status messages. In the error message bar, you can select
one of the error messages to open a dialog box that can help you to remedy the error.
Refer to the table below for information about which error message opens which dialog
box.
Table 6-3: List of keywords
AC COUP This label is displayed when a measurement is configured to be AC coupled, but
information in the DC range is detected. This situation can yield inaccurate measure-
ment results.
You can avoid this error message by changing the input coupling type.
Selecting the "AC Coup" error message opens a dialog box to configure the RF
input.
IF OVLD Overload of the IF signal path in the A/D converter or in the digital IF.
●
Increase the reference level.
Selecting the "IF OVLD" error message opens a dialog box to configure the ampli-
tude.
INPUT OVLD The signal level at the RF input connector exceeds the maximum.
The RF input is disconnected from the input mixer to protect the device. To re-enable
measurement, decrease the level at the RF input connector and reconnect the RF
input to the mixer input.
Selecting the "Input OVLD" error message opens a dialog box to configure the ampli-
tude.
LOUNL Error in the instrument's frequency processing hardware was detected.
