ZVA/ZVB/ZVT CALCulate
1145.1084.12 6.69 E-6
CALCulate<Ch/Tr>:LIMit:RDOMain:SPACing LINear | LOGarithmic | dB | SIC
Deletes the existing limit line and (re-)defines the physical units of the response values of the limit line.
The units of the stimulus values are defined via
CALCulate<Ch/Tr>:LIMit:CONTrol:DOMain.
This command is complemented by
CALCulate<Ch/Tr>:LIMit:RDOMain:COMPlex
and
CALCulate<Ch/Tr>:LIMit:RDOMain:FORMat
.
<Ch/Tr> Channel number used to identify the active trace.
Parameters
Keyword for the physical unit of the response values.
Range [def. unit] The analyzer uses dB units, irrespective of the parameter
selected.
[–]
*RST value –
SCPI, Command
Types Device-specific, no query.
CALCulate<Ch/Tr>:LIMit:SEGMent<Seg>:AMPlitude:STARt <numeric_value>
Changes the start response value (i.e. the response value assigned to the start stimulus value) of a limit
line segment. A segment must be created first to enable this command (e.g
CALC:LIM:DATA
).
To define the response values of several limit line segments with a single command, use
CALCulate<Ch/Tr>:LIMit:LOWer[:DATA]
or
CALCulate<Ch/Tr>:LIMit:UPPer[:DATA]
.
<Ch/Tr> Channel number used to identify the active trace.
<Seg> Segment number
<numeric_value> Response value
Range [def. unit] Almost no restriction for limit segments; see Rules for Limit Line
Definition.
[dB]
*RST value –
The default response values of a segment that is created by
defining its stimulus values only (e.g. by means of
CALCulate<Ch/Tr>:LIMit:CONTrol[:DATA]
), is –20 dB.
SCPI, Command
Types Device-specific, with query.
