When the cursor is aligned with the KEYS option, press ENTER to display a new screen listing
the function definitions of the number keys and softkeys. Press ENTER a third time to return to
the main user Menu screen.
When the cursor is aligned with the CONTRAST option, use the FREQp and FREQq to adjust
the display contrast level.
The two SWR lines allow you to input specific SWR values (between 1.2 and 3.5) at which the
Analyzer will display the corresponding bandwidths. When the cursor is aligned with either SWR
selection, use the FREQ keys to adjust the displayed value.
Default values: 1.5 and 3.0
When the cursor is aligned with the METER option, press ENTER to display the Analyzer's
remaining battery voltage. The Analyzer will also measure and display the Dc voltage of an
external voltage source connected to the antenna connector.
When the cursor is aligned with the EXTRA FEATURES option, use the ENTER key to toggle this
option ON and OFF. Turn this feature ON to activate the expert mode, which provides nine
additional data blocks and four additional real time screens.
Default: Off
F2: Grid
While viewing the S, Z, R, or X real time screens, press the F2 softkey to superimpose a grid
(graticule) over the plot. The grid allows you to more precisely determine values within a plot.
Press F2 again to remove the grid.
Default: Off
F3: Data Box
Use the F3 softkey to scroll through the data blocks located in the Data Box. This key is useful
because it allows you to access data without having to exit the real time screen. The three data
blocks that are available in both the simple and expert modes include:
W:xxx Fc:xxx
SWR:xxx RL:xxx
Z:xxx R:xxx X:xxx <:xxx
To expand the number of data blocks displayed in the Data Box, enable the expert mode (refer to
the F1: User Menu section). In the expert mode, the following nine data blocks will become
available within the Data Box:
L:xxx C:xxx
BW2.0:xxx Q:xxx

Width, Center Frequency
Standing Wave Ratio, Return Loss
Absolute value, Real component, Reactive component, and
Phase Angle of Impedance
Inductance or Capacitance value relating to the Reactance at
the center frequency; describes the complex conjugate value
of the Inductance or Capacitance needed to resonate a load
to the center frequency
