Auto Length and Loss
Determines the length offset and one-way loss parameters for the receive port of the
active trace. See
Chapter 5.6.1.4, "Auto Length and Loss" , on page 170.
Note:
●
If "Auto Length and Loss" is used with a line connected to a test port, the end of the
line should be left open.
●
To calculate the electrical length offset and loss of port i , you have to select a trace
that uses port i as one of its receive ports. It is not relevant for the "Auto Length
and Loss" function which Port is selected.
If the measured quantity is a ratio, or if it is derived from a ratio, its receiving port is
given as the index of the wave quantity in the numerator. If the active trace shows an
S-parameter S
ij
, then "Auto Length" adds a length offset at port i. If the receive port is
balanced, then the same offset and length is applied to both its physical ports.
Remote command:
[SENSe<Ch>:]CORRection:LOSS<PhyPt>:AUTO
6.14.4 Single Ended Tab
Allows you to specify 2-port deembedding/embedding networks for each physical port.
Such a network is either defined:
●
via its S-parameters stored in a two-port Touchstone file (
*.s2p
) or
●
by selecting a predefined lumped element model and specifying the available
parameters (resistances/conductances, capacitances, inductances)
See Chapter 5.6.2.3, "Circuit Models for 2-Port Networks" , on page 175.
Use the complementary dock widget to activate or deactivate dembedding/embedding
for selected ports (see
Chapter 6.14.1.3, "Single Ended Panel" , on page 553).
Background information
Refer to the section Chapter 5.6.2.10, "Combining Several De-/Embedding Networks" ,
on page 183.
