Furthermore you need to specify which
value of the interference signal is to be
used to normalize the linearization curve.
Reference value of the interference signal to
be used to normalize the linearization curve.
Accepted range:

Note!
If you don't have the polynomials data availa-
ble, see the USB stick provided together with
your X-STREAM analyzer: The subdirectory
Interference Compensation provides a
spreadsheet which you can use to calculate
the polynomials from a set of measurement
values.
This spreadsheet is provided
without any support! The use of
its contents is the sole respon-
sibility of the user.
