- For ACP measurements, use CALCulate:ACPower:OFFSet:LIST:LIMit:NEGative[:UPPer]:DATA and CALCulate:ACPower:OFFSet:LIST:LIMit:POSitive[:UPPer]:DATA.

Relevant Modes

EMI, SA, CAT, NA, NF

Parameters

 

<data>

Data for all limit segments in the following format:

  • n = number of segments, followed by segment data.

  • each segment: State, Type, BegStim, EndStim, BegResp, EndResp

  • Where:

State

0 for limit line disabled

1 for limit line enabled.

Type

Type of limit segment. Choose from
0 - Upper limit
1 - Lower limit

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

Subsequent segments are appended to the data in the same manner.

Examples

'The following writes three upper limit segments for a 40 MHz bandpass filter.

' individual segments are highlighted for readability.
