:INSTrument[:SELect]?
Select the measurement mode. The actual available choices depend upon which
modes (measurement applications) are installed in the instrument. A list of the
valid choices is returned with the INST:CAT? query.
Once an 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 is changed, the
status bits should be read, and any errors resolved, prior to switching modes. Error
conditions that exist prior to switching modes cannot be detected using the
condition registers after the mode change. This is true unless they recur after the
mode change, although transitions of these conditions can be detected using the
event registers.
Changing modes resets all SCPI status registers and mask registers to their
power-on defaults. Hence, 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 default state after power up.
