This subsystem selects the sweep type and the measurement parameter.
Command tree: [SENSe<Chn>:]FUNCtion
Defines the sweep type and the measurement parameter in a single string.
Note: To select a measurement parameter without changing the sweep type, use CALCulate<Ch>:PARameter:MEASure. Use the other commands in the CALCulate<Ch>:PARameter... subsystem to create or delete traces and select measurement parameters.
<Chn> |
Channel number used to identify the active trace. If [SENSe<Chn>:]FUNCtion[:ON] is not used as a query, the number must be 1.
|
'<string>' |
Single string parameter defining the sweep type and the parameter to be measured: <string> = "<sweep_type>:<parameter>". |
Range [def. unit] |
See list of strings below [–]. |
*RST value |
"XFR:S21" '
|
SCPI, Command Types |
Confirmed, command or query
|
Example: |
CALC4:PAR:SDEF "Ch4Tr1", "S11" Create channel 4 and a trace named Ch4Tr1 to measure the input reflection coefficient S11. The trace automatically becomes the active trace. SENS4:FUNC? Check (query) the sweep type and measurement parameter of the active trace. The result is 'XFR:POW:S11'.
|
The following keywords define the sweep type (see SCPI command reference: presentation layer):
XFRequency |
Frequency sweep (Lin. Frequency/Log. Frequency/Segmented Frequency) |
XPOWer |
Power sweep |
XTIMe |
Time sweep |
XCW? |
CW Mode sweep (output variable for query only) |
The following keywords define the measurement parameter (see SCPI command reference: function name):
POWer:S<Ptout><Ptin> |
S-parameter with output and input port number of the DUT, e.g. S11, S21. |
POWer:RATio
A<Ptout> | B<Ptin>, A<Ptout>
| B<Ptin> |
Ratio, e.g. B2, A1 for b2/a1 drive Port 1 |
POWer:A<Ptout> |
Wave quantity with stimulus port number of the analyzer, e.g. A1. |
POWer:B<Ptin> |
Wave quantity with receive port number of the analyzer, e.g. B2. |
POWer:Z<Ptout><Ptin> |
Matched-circuit impedance (converted Z-parameter) with output and input port number of the DUT, e.g. Z11, Z21. |
POWer:Y<Ptout><Ptin> |
Matched-circuit admittance (converted Y-parameter) with output and input port number of the DUT, e.g. Y11, Y21. |
POWer:KFACtor |
Stability factor K Stability factors μ1 or μ2 |
PAE<Ptout><Ptin> |
Power Added Efficiency (PAE) with output and input port number of the DUT, e.g. PAE21 (output variable for query only) |
VOLTage[:DC] DCIN1 |
DCIN2 |
DC Input 1 (DC –1 V...+1 V) or DC Input 2 (DC –10 V...+10 V) |
Note: The mnemonics POWer: and VOLTage: are not used in output strings.
