Tip: This command has no query form. Use CALCulate<Ch>:PARameter:MEASure
<TraceName> to query the measurement result of the trace. CALCulate<Ch>:
PARameter:CATalog? returns a list of all defined traces.
Suffix:
<Ch>
.
Channel number referencing a previously defined channel. If
<Ch> does not exist, it is generated with default channel set-
tings.
Setting parameters:
<TraceName> Trace name, string variable, e.g. 'Trc4'. See "Rules for trace
names" in "Table Area" on page 435. Trace names must be
unique across all channels and diagrams.
If a trace with the selected trace name already exists, the ana-
lyzer 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.
<Result> Measurement result (string variable), see table below.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the
input reflection coefficient S
11
.
DISP:WIND2:STAT ON
Create diagram area no. 2.
DISP:WIND2:TRAC:FEED 'CH4TR1'
Display the generated trace in diagram area no. 2.
Usage: Setting only
Manual operation: See "S-Parameter (selector)" on page 345
Table 7-4: String identifiers for measurement results
Note:
All port numbers in a result identifier refer to logical (=DUT) ports; to avoid ambiguities they must be represented by the same
number of digits (e.g. S21 or S0201). The valid port numbers are determined by the channel's logical port configuration
For details about the measurement results, see Chapter 4.3, "Measurement results", on page 149.
'S11' | 'S12' | ... | 'S0101' | ... Single-ended S-parameters S<i><j> for logical (DUT) ports <i> and <j>. To
avoid ambiguities, <i> and <j> must be specified with the same number of
digits.
'SCD11' | ... S-parameters involving balanced ports must be specified in the form
S<m_i><m_j><i><j>, where <m_i> and <m_j> denote the port modes of the
related logical ports <i> and <j>. In general, for the port modes <m_i><m_j>
all pairs of D (differential, balanced), C (common, balanced) and S (single-
ended, unbalanced) are allowed.
'S11SAM' | 'S11AVG' | 'S12SAM' ...
'SCD11SAM' | 'SCD11AVG' ...
The strings SAM and AVG appended to the S-parameters quantities denote
a normal (sample) or average detector. The observation time for average
detectors is set via [SENSe<Ch>:]SWEep:DETector:TIME
