C The parser recognized a data element different than one allowed for example numeric or string data was expected but block data was encountered More parameters were received than expected for the header for example the KLOCk command only accepts one parameter so receiving SYSTem KLOCk 1 0 is not allowed Fewer parameters were recieved than required for the header for example the KLOCk command requires one parameter so receiving KLOCKk is not allowed A character which is not a legal header separator was encountered while parsing the header for example no white space followed the header thus SRE2 is an error GW INSTEK REMOTE CONTROL 112 Program mnemonic too long 113 Undefined header 114 Header suffix out of range 115 Unexpected number of parameters 120 Numeric data error 121 Invalid character in number 128 Numeric data not allowed 131 Invalid suffix The header contains more that twelve characters see IEEE 488 2 7 6 1 4 1 The header is syntactically correct but it is undefined for this specific device for example XYZ is not defined for any device The value of a numeric suffix attached to a program mnemonic see Syntax and Style section 6 2 5 2 makes the header invalid The number of parameters received does not correspond to the number of parameters expected This is typically due an inconsistency with the number of instruments in the selected group Th
