A standard FieldFox vector network analyzer provides vector transmission and reflection measurements (T/R), or S11 and S21, with magnitude and phase.
The base function of the VNA is a transmission / reflection analyzer (S11, S21), and it can be configured to include full 2-port S-parameters. FieldFox can be ordered with additional capabilities: cable and antenna analyzer, built-in power meter, vector voltmeter, variable DC source, and built-in GPS receiver.
With a full 2-port network analyzer, you can measure the forward and reverse characteristics of your component without having to disconnect, turn around, and reconnect it to the analyzer. The full 2-port calibration gives you the best measurement accuracy possible.
The FieldFox four independent, sensitive receivers provide 94 dB of dynamic range for measurement of high rejection, narrowband devices such as cavity filters.
The receivers also enable full 2-port error correction with the unknown thru method, allowing users to measure non-insertable devices accurately and easily.
The FieldFox calibration engine is the same engine that powers the well-respected Agilent ENA and PNA network analyzers. FieldFox leverages Agilent microwave expertise to deliver consistent measurements with Agilent benchtop VNAs.
With the time domain option, FieldFox computes 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.
