If you are using the status bits and the analyzer mode is changed, the

NOTE

 

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.
