Note
●
Port groups must be created in ascending order, i.e. first create port group 1, then
port group 2 etc.
●
By default there is a single port group, which contains all physical VNA ports
("default port group").
●
Redefinition of an existing port group is not allowed (exception: "default port
group"). Use
SOURce<Ch>:GROup<Grp>:CLEar
to dissolve existing port groups
first.
●
It is not allowed to assign the same physical VNA port to multiple port groups.
●
When a port group is created, the number of ports of the corresponding DUT is set
to the port group size and "aligned" port connections are etablished. The result can
be modified using
SOURce<Ch>:GROup<Grp>:DPORt:COUNt
and
SOURce<Ch>:
GROup<Grp>:PPORt<PhyPort>:DPORt
.
Suffix:
<Ch>
.
Channel number
<Grp> Port group number
Parameters:
<pport1>,<pport2>... Physical VNA port numbers
Example: See
SOURce<Ch>:GROup<Grp>:PPORt<PhyPort>:DPORt
Manual operation: See "Controls and Functions" on page 370
SOURce<Ch>:GROup<Grp>:PPORt<PhyPort>:DPORt <DestinationPort>
R&S ZNBT only!
In "Set" direction this command connects physical VNA port
<PhyPort>
to DUT
<Grp>
port
<DestinationPort>
. The query returns the connected DUT port (if any).
Note
●
The related port group must have been created before using
SOURce<Ch>:
GROup<Grp>:PPORts
.
●
Neither physical VNA ports nor DUT ports may be connected more than once
Suffix:
<Ch>
.
Channel number
<Grp> Port group number
<PhyPort> Number of a physical VNA port in port group
<Grp>
.
Parameters:
<DestinationPort> Number of a port on the related DUT.
Must be smaller than the size of the DUT
<Grp>
(set using
SOURce<Ch>:GROup<Grp>:DPORt:COUNt
).
