The R&S ZNB/ZNBT uses the Clear Signal Solutions AITT-DL implementation of the
Delta-L v4.0 algorithms (see https://clearsig.com/clearsig/tools/#Delta). It allows you to
perform:
●
1L (one line/length) analysis
Typically used for high-volume manufacturing (relative comparison)
●
2L analysis
Typically used for board-quality validation (removes the test fixture impact)
●
3L analysis
Typically used for material characterization (best accuracy, self-validation of
results).

Rohde&Schwarz service.
