De-embedding facility
A typical measurement jig, as shown below, includes input and output networks which introduce errors to
the measured values of the device under test (DUT). For best measurement accuracy, these networks can be
specified (in the form of 2 port s-parameter files) and then used to extrapolate the DUT’s characteristics.
De-embedding allows the effects of the test jig’s input and output networks to be
removed.
The PicoVNA 106 allows you to specify S-parameter files (must be full 2-port data) for the input and output
networks as shown in the figure above so that the de-embedding takes place automatically as the
instrument measures the test jig. After first calibrating as usual, follow the steps below to enable de-
embedding.
1. Select the S-parameter file(s) that represent the embedding network(s) by clicking on the embedding
network check box(es) as shown in
Measurement enhancement
. Check box
Port 1 Network
represents
the input network as shown in the figures in
Reference plane extension and de-embedding
, and
Port 2
Network
represents the output network. The files selected must be full 2-port S-parameter files in
Touchstone format.
2. Click on the radio button in the
Measurement enhancement
window to enable de-embedding.
Once the above steps are completed, starting the measurement will display de-embedded results.
The de-embedding facility relies on S-parameter data for the input or output network (or both) being
available. This data must be in the form of 2-port S-parameter files in Touchstone
format.
