If the SCPI Command interface window is used to send the self-test (*TST?)
command to the L4411A, the “timeout” period may have to be increased to allow
the results to be returned. This is done by entering a timeout period at the top of
the command interface window. The L4411A self-test takes approximately seven
seconds to complete.
