102 Keysight N774xC Series Multiport Power Meter Programming Guide
5 Error Codes
-257 "File name error"
-258 "Media protected"
-260 "Expression error"
-261 "Math error in expression (StatUnitCalculationError)"
Description:
This may occur when the user attempts to transform data in a way that is currently not possible.
Example:
When a powermeter is measuring very small power values in dBm (such as noise power), negative
power values in Watt may also be present (such as when the powermeter calibration wavelength
does not correspond to the wavelength of input signal). The instrument cannot transform negative
Watt values to dBm because the logarithm of a negative value is not defined.
-270 "Macro error"
-271 "Macro syntax error"
-272 “Macro execution error”
[Indicates that a syntactically legal macro program data sequence could not beexecuted due to
some error in the macro definition (see IEEE 488.2, 10.7.6.3.)]
-273 “Illegal macro label”
[Indicates that the macro label defined in the *DMC command was a legal string syntax, but could
not be accepted by the device (see IEEE 488.2, 10.7.3 and 10.7.6.2); for example, the label was too
long, the same as a common command header, or contained invalid header syntax.]
-274 "Macro parameter error"
-275 "Macro definition too long"
-276 “Macro recursion error”
[Indicates that a syntactically legal macro program data sequence could not be executed because
the device found it to be recursive (see IEEE 488.2, 10.7.6.6).]
-277 “Macro redefinition not allowed”
[Indicates that a syntactically legal macro label in the *DMC command could not be executed
because the macro label was already defined (see IEEE 488.2,10.7.6.4).]
-278 “Macro header not found”
[Indicates that a syntactically legal macro label in the *GMC? query could not be executed because
the header was not previously defined.]
-280 "Program error"
-281 "Cannot create program"
-282 "Illegal program name"
