Types
Device-specific, command or query
Example:
SENSe2:UDSParams1:ACTive ON
Enable user-defined ports for channel no. 2 and port no. 1
SENSe2:UDSParams1:PARam '1:a1:b2'
Define a port combining the drive port 1, the reference wave a
1
. (i.e. the source
signal which the analyzer transmits at port no. 1) and the measured wave at port 2
b
2
. The ratio b
2
/a
1
is interpreted as a reflection parameter; a one-port calibration can
be performed for the user-defined port.
[SENSe<Ch>:]UDSParams<Pt>:PARam '<port_string>'
Defines a user-defined analyzer port, based on a combination of generator index/drive port, reference
wave (a), and measured wave (b). A standard analyzer port no. <n> combines the drive port no. <n> with
the waves a
<n>
and b
<n>
. With unequal drive port and wave indices, the interpretation of measured
quantities can be changed; see measurement example for [SENSe<Ch>:]UDSParams<Pt>:ACTive.

Port definition string in the format '<drive port>:<a-wave>:<b-wave>'

SOURce
SOURce<Ch>:CMODe...
This subsystem controls the frequency and power of the internal signal source for Defined Coherence
Mode, configures and starts the source power calibration, and provides output port settings.
Note: The SOURce<Ch>:POWer... subsystem comprises port-specific and general settings. Port-specific
settings are valid for the port specified by the numeric suffix <Pt> (...:POWER<Pt>:...). General settings
are valid for all test ports of the analyzer; the port suffix is ignored. Refer to the description of the individual
commands for more information.
SOURce<Ch>:CMODe:PORT<Pt>:AMPLitude <rel. amplitude>
Defines the amplitude for the coherent signal at port no. <Pt> relative to the amplitude of the reference
