CALCulate Subsystem
This subsystem is used to perform post- acquisition
data processing. In effect, the collection of new
data triggers the CALCulate subsystem. This
subsystem is further divided into two subsections:
limits and markers which are the primary
functions in this subsystem.
Limit Line Subsection
An N9340A allows you to define a limit line for
your measurement. You can then have the
instrument compare the data to your defined limit
and indicate a pass/fail condition.
Refer to TRACe subsystem for more trace
commands.
Delete All Limit Lines in Memory
:CALCulate:LLINe:ALL:DELete
This command clears all limit lines in volatile
memory.
Select the Type of Limit Line
:CALCulate:LLINe[1]:TYPE UPPer|LOWer
:CALCulate:LLINe[1]:TYPE?
This command sets a limit line to be either an
upper or lower type. An upper line will be used as
the maximum allowable value when comparing the
data. A lower limit line defines the minimum value.
Key access: [Limit] > {Limit Mode}
*RST state: Upper
Range: Upper|Lower
