Simplify tap weight computation
The N4980A Multi-instrument BERT software includes a powerful de-emphasis tap
weight computation tool that simplifies the process of computing tap weights, reducing
the time required to a few seconds. Starting from a measured or simulated S-Parameter
file of the data path to be equalized, the software calculates the optimum tap values
necessary to create the ideal compensation filter response. The user can control tap
configurations, so different solutions with different ranges of pre- and post-cursors can
be synthesized. Once the data has been analyzed and desired results obtained, a single
click loads the computed tap weights directly into the N4951B-D17/-D32 pattern
generator head.
