1. On measurement channel 1 press C-1 and place marker 1 at the
beginning of the passband and marker 2 at the end of the passband. Place
markers 3 and 4 at the beginning and end of the stopband. (When using
measurement channel 2, use markers 5 through 8 to deEne the passband

peak-to-peak ripple of the passband, as well as the maximum signal
amplitude in the stopband. The insertion loss is deEned as the minimum
point between markers 1 and 2 with respect to 0 dB. The peak-to-peak
ripple of the passband is defined as the difference between the maximum
and minimum points in the passband (as deEned by markers 1 and 2). The
reject parameter is deEned as the difference between the minimum point
in the passband and the maximum point in the stopband.
