CALCulate<Chn>:LDEViation:SLOPe <Slope>
Defines the slope of the regression line for the linearity deviation calculation.
<Chn>
Channel number used to identify the active trace.
<Slope>
Slope of the regression line
Range [def. unit]
The range depends on the trace format. For the default trace:
–10
15
dB/MHz to +10
15
dB/MHz [dB/MHz]. The increment (UP, DOWN) is 10
-
4
dB/MHz.
*RST value
0 dB/MHz

Types
Device-specific, command or query.
Example:
See CALCulate<Chn>:LDEViation:AUTO
CALCulate<Chn>:LIMit...
This subsystem defines the limit lines and controls the limit check.
CALCulate<Chn>:LIMit:CONTrol[:DATA]
<numeric_value>,<numeric_value>{,<numeric_value>,<numeric_value>}
Defines the stimulus values of the limit line and/or creates new limit line segments.
Rules for creating segments
The following rules apply to an active trace with n existing limit line segments:
 An odd number of values is rejected; an error message –109,"Missing parameter..." is generated.
 An even number of 2*k values updates or generates k limit line segments.
 For n > k the stimulus values of all existing limit line segments no. 1 to k are updated, the existing
limit line segments no. k+1, ..., n are deleted.
 For n < k the stimulus values of the limit line segments no. 1 to n are updated, the limit line
segments n+1, ,..., k are generated with default response values (see
CALCulate<Chn>:LIMit:UPPer[:DATA], CALCulate<Chn>:LIMit:LOWer[:DATA]).
The generated segments are upper or lower limit line segments, depending on the
CALCulate<Chn>:LIMit:SEGMent<Seg>:TYPE setting.
CALCulate<Chn>:LIMit:CONTrol[:DATA] does not overwrite the type setting.
To define additional new limit line segments without overwriting the old segments use
CALCulate<Chn>:LIMit:DATA.
<Chn>
Channel number used to identify the active trace.
<numeric_value>
Pair(s) of frequency, power or time values, to be defined in accordance with the
current sweep type ([SENSe<Ch>:]SWEep:TYPE).
