The query returns the current contents of the Service Request Enable Register.
See “Reading the Serial BERT's Status - Reference” on page 27 for details.
*STB?
IAgilentN490XStatus.SerialPoll
*STB?
The Read Status Byte Query (*STB?) allows the programmer to read the status byte
and Master Summary Status bit. When the status byte is read using the *STB
command, bit 6 of the status byte is referred to as the Master Summary (MSS) bit.
With this query, the status byte is not cleared when the value is read. It always
reflects the current status of all the instrument's status registers.
See “Reading the Serial BERT's Status - Reference” on page 27 for details.
*TST?
IIviDriverUtility.SelfTest (not IVI-compliant)
*TST?
The self-test query starts all internal self-tests and places a response into the
output queue indicating whether or not the device completed the self-tests without
any detected errors. It returns a 0 for success; a 1 if a failure was detected.
Upon successful completion of *TST?, the device settings are restored to their
values prior to the *TST?
For more precise self-test results, use “TEST:EXECute? ” on page 403.
*WAI
*WAI
The *WAI commands allows no further execution of commands or queries until
the No Operation Pending flag is true, or receipt of a Device Clear (dcas) message,
or a power on.
The *WAI command can be used for overlapped commands. It stops the program
execution until any pending overlapped commands have finished. Specifically, it
