Making Measurements 3
Making a Stimulus Response Transmission Measurement
The procedure below describes how to use a built- in tracking generator to measure the rejection of a low pass filter, a type of transmission measurement.
1To measure the rejection of a low pass filter, connect the equipment as shown below.
A 370 MHz low- pass filter is used as a DUT in this example.

2Press [Preset] to perform a factory preset.
3Set the start and stop frequencies and resolution bandwidth:
•Press [FREQ] > {Start Freq} > 100 > {MHz}
•Press [FREQ] > {Stop Freq} > 1 > {GHz}
•Press [BW/SWP] > {RBW} > 1 > {MHz}
4Turn on the tracking generator and if necessary, set the output power to
Press [Mode] > {Track Generator} > {Amplitude (On)} > –10 > {dBm}.
