Creating a Loss Compensation Table
Loss Compensation tables can have a maximum of 501 entries. To create a loss
compensation table proceed as follows.
The Loss Compensation table frequency limits in the Before DUT Table...
are specified in terms of the DUT’s input frequencies and the
After DUT Table... are specified in terms of the DUT’s output frequencies.
This is important when making frequency converting DUT measurements
or using a system downconverter.
