CALCulate:LLINe Subsection
Limit lines can be defined for your measurement . You can then have the
instrument compare the data to your defined limits and indicate a
pass/fail condition .
NOTE
Refer also to :
lMEMory
and :TRACe subsystems for more trace an d
limit line commands.
Control Limit Line Amplitude Interpolation
:CALCulate :LLINe[1]12 :AMPLitude :INTerpolate :TYPE
LOGaritbmicILINear
:CALCulate :LLINe[1]I2 :AMPLitude :INTerpolate :TYPE ?
Selects the type of interpolation done for the amplitude values of th e
designated limit line when comparing to measured data .
Factory Preset
and *RST: Not affected by preset
Remarks: Once this function is defined, the selected type i s
persistent . Persistent means that it retains the settin g
previously selected, even through a power cycle .

Set Fixed or Relative Limit Lines
:CALCulate :LLINe :CMODe FIXedIRELative
:CALCulate :LLINe :CMODe ?
Specifies whether the current limit lines are fixed or relative .
NOTE
If you need to change the domain with
: CALCulate : LLINe : CONTrol : DOMain, do it before this command.
Changing the domain deletes all the existing limit line values .
Factory Preset
and *RST: Not affected by preset
Remarks : For Amplitude Parameters :
Regardless of whether the limit line is based on
frequency or sweep time, amplitude parameters in a
limit line table represent absolute values or relative
values. In fixed, the limit line amplitude values are
specified in absolute amplitude and do not depend o n
