Types
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as measured
parameter for channel and trace no. 1.
FREQ:STAR 100000
Set start frequency to 100 kHz.
FREQ:STOP 10MHz
Set stop frequency to 10 MHz.
Note:
If the stop frequency entered is smaller than the current start frequency
([SENSe<Ch>:]FREQuency:STARt), the start frequency is set to the stop frequency minus the
minimum frequency span ([SENSe<Ch>:]FREQuency:SPAN).
[SENSe<Chn>:]FUNCtion...
This subsystem selects the sweep type and the measurement parameter.
[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 [–].

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 keyword defines the sweep type (see SCPI command reference: presentation layer):
