To Use RF Filter
Statistics The RF filter statistics function measures both the passband and the
stopband (reject-band) of a filter with a single sweep.
1. On measurement channel 1, press 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 define the passband and stopband.)
2. Press .
3. At the end of each sweep, this feature calculates the insertion loss
and peak-to-peak ripple of the passband, as well as the maximum
signal amplitude in the stopband. The insertion loss is defined 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
defined by markers 1 and 2). The reject parameter is defined as the
difference between the minimum point in the passband and the
maximum point in the stopband.
4. See Figure 4-14 for an example of an RF filter statistics search.
