A/B and B/A Measurements
A/B and B/A Measurements
These measurements allow you to use the FieldFox A and B receivers, along
with an external source, to make ratioed measurements.
The image below shows a typical configuration for a B/A magnitude and phase
measurement of a 2-port DUT. This DUT can be an antenna / probe setup.
Using network analyzer terms, the image shows the A receiver as the reference
receiver which measures the signal that is applied to the DUT. The B receiver is
the test port receiver which measures the DUT response.

B/A Transmission measurement with external source
Procedure
1.
Connect the external source’s frequency reference output to the FieldFox
Freq Ref IN
on the top panel. If you are unable to use a common frequency
reference, then increase the IFBW to ensure you are measuring the peak of
the correct signal. After locating and tuning to the signal, you may be able
to lower the IFBW to reduce noise.
2.
On the FieldFox, select
System 7
, then

3.
Press

or
A/B
4.
The FieldFox internal source is NOT used, so the output power setting is
not relevant.
5.
To calibrate, replace the DUT with a THRU connection, preferably by
connecting together the two Power Splitters (shown in green). For low
frequency measurements, TEEs can be used.
6.
Press
Meas Setup 4
, then
Zero
.
7.
Connect the DUT and measure.
These measurements require the “Full 2-port S-parameters” option.
