CALCulate<Ch>:PARameter:NFIGure:CSETtings '<trace>'
Overwrites the current channel settings with the ones that were used during the active (previously
performed) noise figure calibration. The referenced trace must show the noise figure of a device.
<Ch>
Channel number.
'<trace>'
Name of a noise figure trace, e.g. 'Trc4'. See Rules for trace names in the
Trace Manager description.

Types
Device-specific, no query.
Example:
See Noise Figure Measurement (condensed measurement example)
CALCulate<Ch>:PARameter:SDEFine '<trc_name>', 'S11' | ... | 'S0101' | ... | 'SCD11'
| ... | 'Y11' | ... | 'Z11' | ... | 'Y-S11' | ... | 'Z-S11' | ... | 'A1' | ... | 'A01' | ... | 'B1' | ... | 'B01'
| ... | 'B2/A1' | ... 'B02/A01' | ... | 'Pmtr2D1' | ...
Creates a trace and assigns a channel number, a name and a measured quantity to it. The trace becomes
the active trace in the channel but is not displayed.
To display the trace defined via CALCulate<Ch>:PARameter:SDEFine, create a diagram area
(DISPlay:WINDow<Wnd>[:STATe] ON) and assign the trace to this area
(DISPlay:WINDow<Wnd>:TRACe:FEED); see example below. CALCulate<Ch>:PARameter:MEASure
changes the measured quantity of an existing trace.
To select an existing trace as the active trace, use CALCulate:PARameter:SELect. You can open the
trace manager (DISPlay:MENU:KEY:EXECute 'Trace Manager') to obtain an overview of all
channels and traces, including the traces that are not displayed.
Use CALCulate<Ch>:PARameter:DEFine:SGRoup to create traces for all S-parameters
associated with a group of logical ports.
<Ch>
Channel number. <Ch> may be used to reference a previously defined channel. If
<Ch> does not exist, it is generated with default channel settings.
'<trc_name>'
Trace name, string variable, e.g. 'Trc4'. See Rules for trace names in the Trace
Manager description.
Trace names must be unique across all channels and diagram areas. If a trace
with the selected trace name already exists, the analyzer behaves as follows:
 If the existing trace is assigned to the same channel as the new trace, it is
deleted. The new trace is not automatically assigned to a diagram area;
see note above.
 If the existing trace is assigned to a different channel, no new trace can be
created. The analyzer returns an error message.
'S11', ...
Measured quantity (string variable); see list of parameters below.
