[Since RigExpert AA-500 can not determine the sign of reactance, it displays both L
and C parameters.]
5.3.2. Transformers
The analyzer can be used for checking RF transformers. Connect a 50 Ohm resistor to
the secondary coil (for 1:1 transformers) and use
SWR graph
or
R,X graph
modes to
check the frequency response of the transformer. Similarly, use resistors with other
values for non-1:1 transformers.
5.4.
RF signal generator
The output signal level is about +10 dBm for RigExpert AA-200 and about +5 dBm for
RigExpert AA-500 (at the 50 Ohm load). Therefore these analyzers can be used as a
source of RF signal for various purposes. Enter the
SWR mode
or the
Show all mode
,
press
ok
to start, then press the
2
key to generate the uninterrupted RF signal.
