Self tests
There are several built-in self tests in the
AA-650 ZOOM analyzer, which can be
run by the user to make sure the analyzer
is working properly.
Make sure all cables or adapters
are disconnected from the antenna
connector of your analyzer, then press
(OK) to start the first test (Detector
test).
You should see the “Passed” message in
case of success.
Continue with two more tests: the second
(Built-in filter test) and the third (Test
with load). For the third test, make sure
to connect a good 50 Ohm load directly
to the analyzer’s antenna connector. See
page 38 to know more about 50 Ohm
loads.
