NOTE
Chapter 6
Executing *TST? returns the module to its *RST state. *RST causes the FIFO data
format to return to its default of ASC,7. If you want to read the FIFO for *TST?
diagnostic information and you want that data in other than the ASCII,7 format, be
certain to set the data FIFO format to the desired format (FORMAT command) after
completion of *TST? but before executing a SENSE:DATA:FIFO: query command.
•
The C-SCPI type for this returned value is int16.
•
Following *TST?, the module is placed in the *RST state. This returns many of
the module's programmed states to their defaults. See page 3-53 for a list of the
module's default states.
•
*TST? performs the following tests on the HP E1419 and installed Signal
