Error Messages
The instrument receives and detects a trigger command (":TRIG") or an
external trigger signal, but it is ignored due to the timing condition (the
instrument is not in the wait-for- trigger state, for example). Change the setup
so that a trigger command or an external trigger signal can be sent after the
instrument has entered the wait-for- trigger state.
U
-113 Undefined header
A command not defined in this instrument, though not illegal in the syntactic
structure, has been received. For example, when the message
":OUTP:DC:ISOL:FREQ:AUTO ON" is sent instead of the correct program
message ":OUTP:DC:ISOL:LEV:AUTO ON" the message sent is received as an
undefined command by this instrument. See the command reference and use
the correct command.
