2.Perform a factory preset by pressing Preset, Factory Preset (if present).

3.Set the Y-Axis Units to dBm by pressing AMPLITUDE, More, Y-Axis Units, dBm.

4.Since we are only interested in the rejection of the bandpass filter,

tune the analyzer center frequency and span to center the bandpass response and display the rejection ± 50 MHz from the center of the bandpass.

a.Set the span to 100 MHz by pressing SPAN, Span, 100, MHz.

b.Set the center frequency to 200 MHz by pressing FREQUENCY, Center Freq, 200, MHz.

5.Set the resolution bandwidth to 3 MHz by pressing BW/Avg, Res BW, 3, MHz.

6.Turn on the tracking generator and if necessary, set the output power to –10 dBm by pressing Source, Amplitude (On), –10, dBm. See Figure 2-2.

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

To reduce ripples caused by source return loss, use 10 dB (E7401A) or 8 dB (all other models) or greater tracking generator output attenuation. Tracking generator output attenuation is normally a function of the source power selected. However, the output attenuation may be controlled in the Source menu. Refer to specifications and characteristics in your specifications guide for more information on the relationship between source power and source attenuation.
