"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.
"RF OVLD"
Overload of the input mixer or of the analog IF path.
●
Increase the RF attenuation (for RF input).
●
Reduce the input level (for digital input)
"LO UNL"
Error in the instrument's frequency processing hardware was detected.
"NO REF"
Instrument was set to an external reference but no signal was detected on the refer-
ence input.
"OVENCOLD"
The optional OCXO reference frequency has not yet reached its operating tempera-
ture. The message usually disappears a few minutes after power has been switched
on.
"UNCAL"
One of the following conditions applies:
●
Correction data has been switched off.
●
No correction values are available, for example after a firmware update.
●
Record the correction data by performing a self alignment

Error Messages in Remote Control Mode
In remote control mode error messages are entered in the error/event queue of the sta-
tus reporting system and can be queried with the command
SYSTem:ERRor?
. The
answer format of R&S
FSMR3 to the command is as follows:
<error code>, "<error text with queue query>;
<remote control
command concerned>"
The indication of the remote control command with prefixed semicolon is optional.
Example:
The command
TEST:COMMAND
generates the following answer to the query
SYSTem:ERRor?
-113,"Undefined header;TEST:COMMAND"
There are two types of error messages:
●
Error messages defined by SCPI are marked by negative error codes. These mes-
sages are defined and described in the SCPI standard and not listed here.
●
Device-specific error messages use positive error codes. These messages are
described below.
