1 = The Test Set detected an error
while trying to execute a
command. The following events
cause an execution error:
a A <PROGRAM DATA> ele-
ment received in a command
is outside the legal range for
the Test Set or is inconsistent
with the operation of the Test
Set.
b The Test Set could not exe-
cute a valid command due to
some Test Set hardware/firm-
ware condition.
1 = A Test Set dependent error
has occurred. This means that
some Test Set operation did not
execute properly due to some
internal condition, such as over
range. This bit indicates that the
error was not a command, query
or execution error.
1 = An error has occurred while
trying to read the Test Set's
Output Queue. The following
events cause a query error:
a An attempt is being made to
read data from the Output
Queue when no data is
present or pending.
b Data in the Output Queue has
been lost. An example of this
would be Output Queue over-
flow.
1 = The Test Set is requesting
permission to become the active
controller on the GPIB bus.
