-221 Settings conflict
An invalid configuration was requested. This error is most commonly generated 
when setting alarm limits. Note that the lower limit must always be less than or 
equal to the upper limit, even if you are using only one of the limits. This error is 
also generated if you send the MEASure? or CONFigure command with 
autorange enabled with a fixed resolution. 
-222 Data out of range
A numeric parameter value is outside the valid range for this command. 
Example: TRIG:COUNT -3 
-223 Too much data
A character string was received but could not be executed because the string 
length was more than 12 characters. This error can be generated by the 
CAL:STRing and DISPlay:TEXT commands.
-224 Illegal parameter value
A discrete parameter was received which was not a valid choice for this 
command. You may have used an invalid parameter choice. 
Example: TRIG:SOURCE ALARM (ALARM is not a valid choice) 
-230 Data stale
A FETCh? or DATA:REMove? command was received but internal reading 
memory was empty. The readings retrieved may be invalid. 
-310 System error
A firmware defect has been found. This is not a fatal error but you should contact 
your nearest Keysight Service Center if this error is reported. 
-350 Error queue overflow
The error queue is full because more than 10 errors (34970A) or 20 errors 
(34972A) have occurred. No additional errors are stored until you remove errors 
from the queue. The error queue is cleared by the *CLS (clear status) command 
or when power is cycled. The errors are also cleared when you read the queue. 
-410 Query INTERRUPTED
A command was received which sends data to the output buffer, but the output 
buffer contained data from a previous command (the previous data is not 
overwritten). The output buffer is cleared when power has been off or after a bus 
Device Clear.
