*TST?
*TST? causes the Agilent E1441A to execute its internal self-test and returns a value
indicating the results of the test.
A zero response indicates that the self-test passed. Any non-zero response indicates
that the test failed. Use the SYST:ERR? command to read the error and description
from the error queue. Note the error number and description returned in the error
message. See Appendix B, Error Messages, for information on interpreting the error
number and description response(s).
The settings for all SCPI commands are unchanged by this command.
