SECTION 2.
QUICK START
To help you get started, we've included this brief tutorial, which leads you through the general
functions of the Analyzer.
First, press the ON key to activate the Analyzer. An introductory screen will flash briefly on the
display, followed by a simple SWR plot. Since there is no antenna connected to the Analyzer, the
plot is given an out-of-range value represented by a straight line across the top of the display.
Use the F5 softkey to toggle between the S (SWR) screen and the Z (total Impedance) screen.
Notice that the boxed letter in the lower right corner changes as you toggle between the two
screens. This letter identifies the screen that is currently displayed (refer to Screens section).
Before continuing, return to the S screen.
Use the F3 softkey to scroll through the three data blocks displayed below the horizontal axis.
Before continuing, return to the "W:100K:DIV Fc:14.200" data block. This data block provides the
plot's default width (W:) and center frequency (Fc:) values. Change the center frequency to 1.900
Mhz by entering 1 9 0 0 ENTER on the keypad. Now, press the WIDTHq key three times to set
the width to 10 kHz. The data block should now read "W:10K:DIV Fc:1.900".
To simulate actual operation, (with the Analyzer still on) attach the feedline of an 80-meter
antenna to the antenna connector on top of the Analyzer. The S screen and "W:10K:DIV
Fc:1.900" data block should still be displayed. Set the center frequency to 3.900 MHz by entering
3 9 0 0 ENTER on the keypad. The Analyzer will now sweep around this center frequency value.
Now, use the WIDTH keys to experiment with different frequency sweep ranges. Also, use the F4
softkey to adjust the vertical scale (zoom factor). A well-matched antenna will produce a typical
"V" or "U"-shaped SWR curve. Use the F3 softkey to obtain exact SWR, Return Loss, and total
Impedance readings, or press the EXAM/PLOT key to freeze the display when an interesting plot
appears. (Press EXAM/PLOT again to resume normal operation.)
Now, press the F1 softkey to enter the user menu screen. Press the WIDTHq key until the cursor
aligns with the EXTRA FEATURES option. Press ENTER to turn this option ON. This will enable
the additional screens and data blocks included in the expert mode. Press the F1 softkey again to
return to the S screen. Now, use the F5 softkey to scroll through four new screens; use the F3
softkey to scroll through all 12 data blocks.
