Troubleshooting Data Acquisition


If a problem occurs with data acquisition, check the following items.


If data is improperly acquired when connecting to the instrument.


• Is the message terminator (delimiter) set properly?

→ Refer to the Terminators and separators.
→ Refer to Setup Procedure.

If only one response is received after multiple queries have been sent.


• Has an error occurred?

→ Send the "*ESR?" query to check the Standard Event Status Register for anomalies.
→ The response should be read immediately after each query.
→ To read multiple responses in one operation, the corresponding queries must be combined into a single line using message separators.

If the instrument does not execute a command after it has been sent.


• Has an error occurred?

→ Send the "*ESR?" query to check the Standard Event Status Register for anomalies.
→ Not all commands can execute during measurement operation. However, the ":ABORT" command is executed as soon as it is received.
→ An error has occurred while executing a command.

If after sending a command to change a setting, the change is not displayed on the instrument.


• Is the screen updating mode set to FALSE (disabled)?

→ Send the :DISPlay:UPDAte? command to check the state of the screen updating mode.
→ Send the :DISPlay:UPDAte TRUE command to enable screen updating.
