Note
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:DATA
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 66 for a list of the
module’s default states.
•
*TST?
