SCPI Status Bits/
OPC Dependencies: If you are using the status bits 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.
ChangingmodesresetsallSCPIstatusregistersandmaskregistersto
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.
Factory Preset: 1 (Spectrum Analysis)
If
Preset Type Mode is selected, then the analyzer settings are preset but it
stays in that selected mode.
Remote Command:
:INSTrument:NSELect <integer>
:INSTrument:NSELect?
Remote Command Notes: Enter one of the following integers in the command to set the
analyzer mode.
