TIP. Modulation filters
In most modulation schemes, signals are filtered to reduce the bandwidth prior to transmission. When the signal
under test has been passed through a modulation filter, a matching Measurement Filter should be selected in the
instrument in order to interpret symbols properly. The Reference Filter, while not used for demodulation, is
important for making the proper error vector measurement calculations. This filter will normally be defined by the
modulation/demodulation standard.
