RF phase flatness (160 MHz) ± 2 degrees measured
User channel correction (256 taps)
Automated routine uses power sensor to correct for linear phase and amplitude response of DUT (equalizer) . See Users Guide for
more details .

Equalization filter (256 taps)
User can download and apply inverse or custom phase and amplitude response coefficients from tools such as MATLAB, 89600 VSA
or SystemVue to correct for linear errors of DUT/system . See Users Guide for more details .
