CALCulate<Ch/Tr>:LIMit...
This subsystem defines the limit lines and controls the limit check.
CALCulate<Ch/Tr>: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:
ƒ
An odd number of values is rejected; an error message –109,"Missing parameter..." is
generated.
ƒ
An even number of 2*k values updates or generates k limit line segments.
ƒ
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.
ƒ
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<Ch/Tr>:LIMit:UPPer[:DATA],
CALCulate<Ch/Tr>:LIMit:LOWer[:DATA]
).
The generated segments are upper or lower limit line segments, depending on the
CALCulate<Ch/Tr>:LIMit:SEGMent<Seg>:TYPE setting.
CALCulate<Ch/Tr>:LIMit:CONTrol[:DATA]
does not overwrite the type setting.
To define additional new limit line segments without overwriting the old segments use
CALCulate<Ch/Tr>:LIMit:DATA
.
<Ch/Tr> 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 domain setting
(
CALCulate<Ch/Tr>:LIMit:CONTrol:DOMain
).
Range [def. unit] Almost no restriction for limit segments; see Rules for Limit Line
Definition. [Hz for frequency sweeps, dBm for power sweeps, s for
time sweeps]
*RST value –
A segment that is created implicitly, e.g. by means of
CALCulate<Ch/Tr>:LIMit:UPPer[:DATA]
or
CALCulate<Ch/Tr>:LIMit:LOWer[:DATA,]
, covers the
maximum sweep range of the analyzer.
