Description
"1" is set when all the operations of the overlap command
sent before sending "*OPC" command on page 259.
"1" is set when the 4294A requests GPIB control to
continuously operate for controlling its peripheral
devices.
1. "1" is set when the 4294A receives a query request,
but there is nothing in the output queue to transmit.
2. "1" is set when data in the output queue is lost.
"1" is set when an error, other than a command error, a
query error, and an execution error occurs.
1. "1" is set when any parameter in an GPIB command
exceeds its input range, or is inconsistent with the
4294Acapabilities.
2. "1" is set when an GPIB command could not be
properly executed due to some condition of the
4294A.
1. "1" is set when an IEEE 488.2 syntax error has been
occurred (a command sent to the 4294A does not
follow the IEEE 488.2 syntax). Possible violations
include, the command parameter violates the 4294A
listening formats or is unacceptable to the 4294A.
2. "1" is set when a semantic error occurs. Possible
causes include, a command which contains
misspelling was sent to the 4294A, or an IEEE 488.2
command that was not supported by the 4294A was
sent.
3. "1" is set when GET (Group Execution Trigger) is
inputted to the program input buffer.
"1" is set when an operator presses a front panel key, a
key on the keyboard connected to the 4294A, or turns the
rotary knob.
"1" is set when the 4294A is powered ON.
