[SENSe<Chn>:]FUNCtion...    Related Topics

This subsystem selects the sweep type and the measurement parameter.

 

Command tree: [SENSe<Chn>:]FUNCtion

[:ON]

[SENSe<Chn>:]FUNCtion[:ON] '<string>'

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>
Output: 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
POWer:MUFactor<1|2>

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
Output: DC 1 V, DC 10 V

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.
