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'.
The following keywords define the sweep type (see SCPI command reference: presen-
tation 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 refer-
ence: function name):
POWer:S<Ptout><Ptin>
S-parameter with output and input port number of
the DUT, e.g. S11, S
21
.
POWer:RATio A<Ptout> | B<Ptin>,
A<Ptout> | B<Ptin>
Output: A<Ptout>/B<Ptin>
Ratio, e.g. B2, A1 for b
2
/a
1
drive Port 1
POWer:A<Ptout>
Wave quantity with stimulus port number of the ana-
lyzer, e.g. a
1
.
POWer:B<Ptin>
Wave quantity with receive port number of the ana-
lyzer, e.g. b
2
.
