This panel can also be activated by selecting the Differential Match Tab softtool tab.
Refer to its description of this softtool tab for background information, parameters and
additional remote commands.
Active
The checkboxes in the "Active" column activate or deactivate the configured differential
match embedding (i.e. adds or removes it to/from the calculation flow) without chang-
ing its parameters.
Remote command:
CALCulate<Ch>:TRANsform:VNETworks:DIFFerential:
EMBedding<LogPt>[:STATe]
File Name 1
The ellipsis button in the "File Name 1" column is enabled if a 2-port data Network is
selected.
When loading the touchstone file (
*.s2p
), the analyzer by default assumes odd ports
left (VNA side), even ports right (DUT side). However, it is also possible to "Swap
Gates" , instructing the analyzer to reinterpret the loaded S-parameters (e.g. S
12
-->
S
21
).
Note: The loaded S-parameter traces are stored in the active recall set. Persisted
recall sets contain the full embedding and deembedding data so that they can be trans-
ferred to other instruments.
Remote command:
MMEMory:LOAD:VNETworks<Ch>:DIFFerential:EMBedding<LogPt>
6.14.2 Offset Tab
Defines length offset parameters for each port.
Use the complementary dock widget to activate or deactivate length/loss compensation
for selected ports (see

The marker function Zero Delay at Marker function overwrites the offset parameters.
