SECTION 3.
OPERATION
SETUP
Attach the load under test to the antenna connector, which is located on the top of the Analyzer.
Press the ON key to activate the unit.
CAUTION: Do not connect any transmitting equipment directly to the antenna connector.
Excessive RF at the antenna connector will damage the Analyzer. Damage may also occur when
the load under test is near a transmitting antenna. In addition, never leave the Analyzer attached
to an antenna after testing is complete; a lightning storm in the vicinity may damage the
Analyzer's sensitive bridge network. Damage resulting from these situations is not covered under
warranty.
NOTE: The Analyzer's sensitive instrumentation may cause erroneous readings (elevated
minimum SWR values) to occur in the presence of RF fields (i.e. near commercial broadcast
stations). To reduce the potential for interference, the Analyzer's output power is less than 5 mW.
With a good antenna match, however, the reflected power can be up to 20dB lower, alevel that
can be masked by other transmitters.

SCREENS

The Analyzer provides seven real time screens, which include two data screens and five graphing
screens.
The two real time data screens include the Data screen and the Numerical Entry screen. The
Data screen consolidates much of the information displayed in the Data Box (described below).
The Data screen specifically displays: center frequency, SWR, Return Loss, Bandwidth2.0, Q
factor, Resistance, Reactance, Impedance, Phase Angle, Capacitance, and Inductance values.
The Numerical Entry screen cannot be accessed by any of the function keys, but will
automatically appear whenever you enter numbers on the keypad. The numbers will appear
onscreen as they are entered. To terminate an entry and resume normal operation, press the
ENTER key or one of the FREQ keys (refer to Dedicated Keys section).
