Choosing a network analyzer
The frequency and sensitivity requirements of your antenna system will determine the
network analyzer specifications. Agilent offers three families of network analyzers: the
PNASeries,thePNA-LSeriesandtheENASeries.Agilenthasdevelopedoptionsfor
the PNA Series specifically for antenna measurements. Because of these options, the
PNA Series is often the preferred analyzer for antenna solutions. However, there are
applicationswhichdonotrequiretheseoptionsandthelowercostPNA-LSeriesor
ENA Series analyzers may be the right solution. For secure environments, a PNA or
PNA-LSeriesanalyzermustbeused.Selectananalyzerfromthefollowingtablethat
meets your frequency and sensitivity requirements.
RefertotheENAdatasheet,literaturenumber5988-3780ENorthePNAandPNA-L
data sheets, literature numbers 5988-7988EN and 5989-0514EN for more detailed
information.
What to do if the sensitivity requirement cannot be met
If the AUT is located far from the analyzer, requiring long cables, then the loss caused
by the cables could be significant, reducing accuracy and dynamic range. You may also
be unable to find an analyzer that meets your sensitivity requirements. In this situation,
downconvertingthesignaltoanIFsignalbyusingthe85309LO/IFdistributionunit
with 85320A/B remote mixers brings the measurement closer to the AUT. This reduces
RF cable loss and maximizes accuracy and dynamic range. Options H11 and 014 on the
PNA network analyzers both support a remote mixing configuration. Refer to “Receive
site configuration with external mixing” to configure your system.
