Command Errors
The instrument parser detected an IEEE 488.2 syntax error. Errors in
this class set the command error bit (bit 5) in the event status register
(IEEE 488.2, section 11.5.1). In this case:
• Either an IEEE 488.2 syntax error has been detected by the parser
(a control-to-device message was received that is in violation of the
IEEE 488.2 standard. Possible violations include a data element
which violates device listening formats or whose type is
unacceptable to the device.), or
• an unrecognized header was received. These include incorrect
device-specific headers and incorrect or unimplemented IEEE 488.2
common commands.
-160
Block data error
This error, as well as errors -161 through -169, are
generated when parsing a block data element. This
particular error message is used if the device cannot
detect a more specific error.
-168
Block data not allowed
A legal block data element was encountered, but not
allowed by the device at this point in the parsing.
-140
Character data error
This error, as well as errors -141 through -149, are
generated when parsing a character data element. This
particular error message is used if the device cannot
detect a more specific error.
-148
Character data not allowed
A legal character data element was encountered where
prohibited by the device.
-144
Character data too long
The character data element contains more than twelve
characters (see IEEE 488.2, 7.7.1.4).
