Configuration and Start-up Errors
The Agilent E1406 Command Module error messages associated with
system installation and configuration are shown on the following pages.
These messages are displayed if a terminal or printer is connected to the
Command Module’s RS-232 port. If a terminal or printer is not used, the
messages can be read from the system instrument error queue, using
SYST:ERR?. An BASIC example using SYST:ERR? is shown below:
DIM Err_msg$[256]
REPEAT
OUTPUT 70900;"SYST:ERR?"
ENTER 70900;Code,Err_msg$
PRINT Code,Err_msg$
UNTIL Code=0
NOTE Error codes read from the error queue are preceded by the number 21. For
example, error code 11 displayed on a monitor would appear as 2111 if
read from the error queue instead.
NOTE If a fatal error has occurred and the system instrument is not started,
SYST:ERR? cannot be used to read the error queue.
