6.1 Troubleshooting
(1) The setting does not become valid even though the setting command is sent.
Send ":SYST:ERR?" command to check the error contents. After that, send the correct command.
(Example) Parameter value beyond the setting range is specified.
(2) Command process time
According to the command, it takes a long time to make the setting, causing "Timeout Error" to occur.
If this occurs, wait for enough time after the command has been sent and send the next command or send
the next command after the command has been completed by the OPC command.
(Example) The completion of the command is checked with :SLOT:OPC command.
zThe following shows the response of :SLOT:OPC? command.
0: Command is being processed.
