Figure 5. Typical antenna measurement conguration using PNA network analyzers
with Option H11.
Fast PNA-X data acquisition time and more than 400,000 points of data per second with
the PNA-X measurement receiver makes it the ideal choice for far-eld antenna range
applications. With the PNA bandwidth set to 10 kHz, the data acquisition time is 119 uS
per point. With the PNA-X bandwidth set to 600 kHz, the data acquisition time is 2.4
uS per point. Extremely fast data processing is particularly useful in applications where
ranges include active array antennas and data acquisition is quite intensive. Alternatively,
these features may not be as useful when there are antennas with limited positioner
rotation speeds. Overall, with faster data acquisition speeds, the IF bandwidth can be
narrowed; signicantly improving measurement sensitivity without increasing total mea-
surement times.
