Error messages
Error number: -220
Another measurement was being executed and the measurement start request was ignored.
-220 Parameter error
An error not included in error numbers between -221 and -229 occurred during the analysis
of a program data element. This error occurs, for example, when you attempt to specify an
invalid value for the LOAD correction reference value or the LOAD correction data
(values that are not finite when converted to R-X form impedance values). If this error
occurs, the command is ignored. This error also occurs when you attempt to specify an
invalid LOAD correction reference value from front panel keys.
-221 Setting confict
A program data element complying with the syntax standard was analyzed but the 4294A
could not execute it at present.
-222 Data out of range
A data element (that did not violate the standard) out of the range the 4294A defined was
received.
-223 Too much data
The received block, equation, or string type program data complied with the standard but
its amount exceeded the limit that the 4294A could deal with, due to memory or
device-specific conditions related to memory.
-224 Illegal parameter value
The value of the parameter is illegal.
-225 Data out of memory
To perform the requested operation, the 4294A does not have enough memory.
-230 Data corrupt or stale
The data may be invalid. Or, a newly initiated read operation has not been completed since
the latest access.
-231 Data questionable
Data may be questionable. The accuracy of measurement data may be deteriorated.
-240 Hardware error
A hardware error.
The program command could not be executed due to an hardware-related error. An error
other than -241 to -249 occurred.
-241 Hardware missing
The received command or Query complied with the standard but could not be executed due
to hardware-related reasons (for example, the option was not installed).
-250 MASS STORAGE ERROR
A mass storage error occurred.
A mass storage error other than -257 occurred.
-252 Missing media
You attempted to access the storage device, but media did not exit or was not installed
