The lEEE 488.2 standard defines certain bits in the status registers
as
error
condition flags. When an error occurs, one
of
the error bits
is
set in the status
registers. The bit enable masks and the service request enable allow the
28324 to alert the remote controller that an error has occurred. The standard
allows error numbers that range from
-100
to
499.
When using the RS232C port the RS232 Echo Mode controls when errors are
returned. When the Echo Mode
is
enabled the errors are returned immedi-
ately. When the Echo Mode
is
disabled the errors are not returned immedi-
ately and the *ERR? command must be used to retrieve the errors.
Command
Errors
Command Errors are associated with the conversion
of
the data received into
the commands and their parameters barsing). Incorrect syntax, incorrect
parameters, and improper command format will generate these errors. Any
command error will cause the Command Error bit @it
5)
in the Standard
Event Status Byte to be set.

02,
"Syntax
error"
Occurs when an error in command structure or parameter type is detected.
Some typical causes are:
Using a number as a command mnemonic.
Using the wrong parameter type.
Using ASCII characters outside of a string constant that are not defined by
the command language syntax.
Missing or too many parameters.
The above list in not exhaustive but does give the basic idea of what to look
for.

10, "Command header error"
This error
is
generated when the system parser detects an invalid character in
a command header.
-1
13, "Undefined Header"
This error
is
generated when the 2832-C
does
not recognize a command
header.
