Observe the Characteristics of the Filter
needed to avoid overdriving the next stage of the DUT (if that stage contains an amplifier) or
the network analyzer receiver.
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 passband of
the filter. For this example, the following ranges will be used:
Lower stopband.. . . . . . . , . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . , . . . . . . . . . . . . . . . . . . . . . . .650 to 880 MHz
Upper stopband . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 920 to 1150 MHz
