Network Measurement with Spectrum Monitor
During a network measurement, crosstalk or leakage (such as noise)
from an adjacent circuit can change the measurement results . T o
detect the e ect of these spurious inputs , the analyzer can monitor
the spectrum of the input signal at the R, A, and B inputs .

Circuit
Measurement Setup In this example , the network measurement circuit has leakage from
an adjacent signal source . The frequency of the signal source is
240 MHz and the DUT is a 250 MHz bandpass lter .
