Critical Note: CALCulate commands act on the selected measurement. You can select one measurement for each channel using Calc:Par:MNUM or Calc:Par:Select. Learn more.

CALCulate<cnum>:LIMit:DATA <block>

(Read-Write) Sets data for limit segments.

See Critical Note

Parameters

 

<cnum>

Channel number of the measurement for which limit lines are to be set. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.

<block>

Data for all limit segments in REAL,64 format. The following is the data format for 1 segment:
Type,BegStim, EndStim, BegResp,EndResp

Type

Type of limit segment. Choose from
0 - Off
1 - Max
2 - Min

BegStim

Start of X-axis value (freq, power, time)

EndStim

End of X-axis value

BegResp

Y-axis value that corresponds with Start of X-axis value

EndResp

Y-axis value that corresponds with End of X-axis value

Examples

The following writes three max limit segments for a bandpass filter.
