Network analyzer time domain

With the time domain Option, FieldFox com-

putes the inverse Fourier transform of the

frequency-domain data to display reﬂection

or transmission coefﬁcients versus time.

Time domain gating can be used to remove

unwanted responses such as connector

mismatch or cable discontinuities, and the

results can be displayed in either time or

frequency domain. FieldFox’s time domain

function supports both low pass mode and

band pass mode, enabling users to measure

both broadband and frequency-selective

devices.

Network analysis

S11, S11 phase, Smith chart and polar

display are available with Option 303 (Net-

work analysis capability). To obtain S21or

insertion loss/gain, users need to order

Option 110 (transmission measurement),

in addition to Option 303.

For in-ﬁxture measurements, use FieldFox’s

port extension or electrical delay capabil-

ity to easily extend the reference plane to

the device interface to provide accurate

measurements. You can use the electrical

delay capability to measure deviation from

linear phase by removing the linear portion

of the phase delay.

If you need to measure the magnitude and

phase of all four S-parameters, consider the

N9923A FieldFox RF VNA. Please refer to

Agilent FieldFox RF Vector Network Ana-

lyzer, literature part number 5990-5087EN.
