INSTrument Subsyste m
INSTrument Subsystem
This subsystem includes commands for querying and selecting
instrument measurement (personality option) modes .
Select Application
:INSTrument[ :SELect] SAI(application specific mode )
:INSTrument[ :SELect] ?
Select the measurement application (mode) by enumerated choice . Th e
actual available choices depends upon which applications (modes) are
installed in the instrument. See the manual that was part of the
installed option for the mode designator (if any) of that option .
Once the instrument mode is selected, only the commands that are
valid for that mode can be executed .
NOTE
If you are using the SCPI status registers and the analyzer mode i s
changed, the status bits should be read, and any error condition s
resolved, prior to switching modes . Error conditions that exist prior t o
switching modes cannot be detected using the condition registers afte r
the mode change . This is true unless they recur after the mode change ,
although transitions of these conditions can be detected using the even t
registers.
Changing modes resets all SCPI status registers and mask registers t o
their power-on defaults . Therefore, any event or condition register
masks must be re-established after a mode change. Also note that the
power up status bit is set by any mode change, since that is the defaul t
state after power up.
