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.
1 To 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.

2 Press [Preset] to perform a factory preset.
3 Set 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}
4 Turn on the tracking generator and if necessary, set
the output power to –10 dBm:
Press [MODE] > {Track Generator} > {Amplitude (On)}
> –10 > {dBm}.

CAUTION
Excessive signal input may damage the DUT. Do not exceed
the maximum power that the device under test can tolerate.
