Observe the Characteristics of the Filter
Figure 2-51. Characteristics of a Filter
Generally, the
of a
exhibits low loss. A relatively low incident power may be
needed to avoid overdriving the next stage of the DUT (if that stage contains an amplifier) or
the network analyzer receiver.
Conversely, the
of a
generally exhibits high isolation. measure this
characteristic, the dynamic range of the system will have to be maximized. This can be done
by increasing the incident power and narrowing the IF bandwidth.
Choose the Measurement Parameters
1. Decide the frequency ranges of the segments that will cover the stopbands and
of
the filter. For this example, the following ranges will be used:
