Error Messages - ILX Lightwave LDX-3200 Series User Manual

All LDX-3200 Series' device-dependent commands are executed in an overlapped manner, except the "DELAY"
command which is sequential. The operation complete flag is set after the conditions outlined in the Operation
Complete Definition have been satisfied.
The *WAI (common command) is an example of a sequential command which forces the next command to wait until
the no-operation-pending flag is true. This is essentially the same as waiting for the OPC flag to become true,
because the no-operations-pending flag is used to set the OPC flag (bit 0 of the Standard Event Status Register).
Commands which change the status of the instrument limits, or change its mode or current range, step value, or
status enable registers, will not have their OPC flag set until all current writing to non-volatile memory has been
completed. This is done to ensure that the OPC flag is never set prematurely.
Whenever there is any output (response) data in the Output Queue, bit 4 is set in the Status Byte Register.
Whenever there is any error message in the Error Queue, bit 7 is set in the Status Byte Register.

Error Messages

In the event of a hardware error condition, error messages will be displayed on the display
message will appear for three seconds. In some cases the error code display will remain until the user changes display
modes. In the case of multiple error messages, the display may sequentially show each message for three seconds. In
addition to the hardware errors, GPIB errors may be read via the "ERR?" query. Table 3.4 lists the numerical error
ranges by function. Table 3.5 contains all of the error messages which may be generated. Not all of these messages
may appear on the front panel displays
In remote operation, the errors can be read by issuing the "ERR?" query. When this is done, all of the error messages
which are resident in the error queue are returned (up to 10 may be stored). Reading the error queue via GPIB clears
the error queue.
