I’m using the SIGNAL I/O connector to start and stop tests and the RS232C interface to retrieve measurement results on TOS5200. What should I do if the second test fails to start?

When retrieving measurement data via the RS232C interface, TOS5200 enters the remote mode, which deactivates the start signal from the SIGNAL I/O connector. To restart the test, you can either: Return to the local mode after the test, or 2. Configure the trigger source properly if you want to remain in the remote mode. Please read the communicationinterface manual for more details.
