Understanding the Operating Modes
The Antenna Tester is connected and the cellular sys-
tem is selected (see basic operation). User selections
are customized, the power is on, and the top level
menu is displayed (also in basic operation).
Since the AT-800 changes the way antennas are tested,
take some time to explore the different operating modes
and find what is best for individual applications.
Swept Frequency vs. Single Frequency
Swept frequency graphically displays the measurement
over a band of frequencies. The cursor, a vertical dotted
line, can be moved with the arrow keys to pinpoint a
particular frequency. The frequency and match value at
the cursor position are shown at the top of the display.
