3 Making Measurements
5Reduce the span to 1 MHz and if necessary re- center the peak.
•Press [SPAN] > [1] > {MHz}.
6Set the attenuation to 20 dB. Note that increasing the attenuation moves the noise floor closer to the signal level.
•Press [AMPTD] > {Attenuation} > 20 > {dB}.
Figure 7 A signal closer to the noise level (Atten: 20 dB)
7Press [AMPTD] > Attenuation > 0 > {dB} to set the attenuation to 0 dB.
Figure 8 A signal closer to the noise level (Atten: 0 dB)
