Using Instrument Functions
Using Markers
To Use RF Filter
Statistics
The RF filter statistics function measures both the passband and the stopband
(reject-band) of a
Elter
with a single sweep.
1. On measurement channel 1 press
(WJ
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.)
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
dR.
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 stats search.
