Error Handling
T100S-HPThe two following types of errors can occur in the transmission of instructions:
•
Command error: the command string received by the T100S-HP is invalid due to a
syntax error or to the use of an unknown mnemonic.
•
In RS-232C, the message is
COMMANDERROR
•
In GPIB, the ERRC indicator in the status byte register is activated.
•
Value error: the command is correctly formulated, but the value of the parameter is
incorrect, either because it could not be read or because it is outside the valid range.
In both cases, the provided command is ignored.
•
In RS-232C, the message is
VALUEERROR
•
In GPIB, the ERRV indicator in the status byte is activated.
In GPIB, no message contains the error; it is only set in the STB: both ERRC and ERRV
indicators are automatically reset when a new valid command is received.
