IEEE-488.2 Common Command Reference
294 HP E1415 Command Reference
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 "*RST" on page 291.
for a list of the module's default states.
•
