SOURce<Ch>:GROup<Grp>:PORTs
<arg0>[, <arg1>]...
Defines the set of active logical ports (the "master group") as an arbitrary selection of
logical ports. The ports do not have to be numbered consecutively (as for port groups
defined via
See
on how to define logical ports.
Suffix:
<Ch>
.
Channel number.
<Grp>
Port group number, must be 1 (or omitted).
Parameters:
<arg0>
<arg1>
Logical port numbers. Must be omitted if the command is used
as a query.
SOURce<Ch>:GROup<Grp>:PPORts
<pport1>,<pport2>...
Defines/queries port groups.
In "set direction" this command creates port group
<Grp>
from physical VNA ports
<pport1>, <pport2>, ...
. In "get direction" it returns the physical VNA ports
making up group
<Grp>
.
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
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.
