Example:
FUNC "XFR:POW:S12"
Activate a frequency sweep and select the S-parameter S
12
as
measured parameter for channel and trace no. 1.
SWE:SPAC LOG
Change to sweep type "Log Frequency".
[SENSe<Chn>:]FUNCtion[:ON]
<SweepType>[, <arg1>, <arg2>]
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.
Suffix:
<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.
Parameters:
<SweepType>
Single string parameter defining the sweep type and the param-
eter to be measured:
<string> = "<sweep_type>:<parameter>"
.
Range:
See list of strings below.
*RST:
"XFR:POW:S21"
<arg1>
B1 | B2 | A1 | A2 | ABSa1 | ABSa2 | DCIN1 | DCIN2
<arg2>
B1 | B2 | A1 | A2 | ABSa1 | ABSa2 | DCIN1 | DCIN2
Example:
CALC4:PAR:SDEF "Ch4Tr1", "S11"
Create channel 4 and a trace named "Ch4Tr1" to measure the
input reflection coefficient S
11
. 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'
.
