Channel Table
The channel table screen allows a user to select up to 30 chan-
nels in either band for closer inspection. These channel ‘lists’
are created with the separate channel table editor which runs
on the PC.
After pressing the channel table button on the main menu,
select a file on the iPAQ containing the desired channel table
for this scan. After the table has been selected, the channel
table display screen will appear and begin scanning.
Spectrum Analysis
The spectrum analysis feature of the Wolf allows a user to
view any RF signals that is received by the receiver. It uses
frequency for the X-axis and RSSI (received signal strength
indicator) in dBm on the Y-axis.
When pressing the spectrum analysis button on the main
menu, an option screen appears. Here is where the band,
center frequency, and span (in MHz or channels) are set. Be
aware not to choose a span that is wider than the width of
the band. For example, the cellular band is 869.01-893.97,
therefore the maximum width is 24.96 MHz, using 881.52 as
an approximate center frequency.
After these options have been set, the ‘OK’ button will bring
the user into the spectrum screen itself. The white bar moving
horizontal across the screen is there to show that the unit is
indeed scanning. Similar to the radar sweep indicator which
is found on radar.
There are three available traces. They are red, blue, and yel-
low traces. Only one trace can be active at any one time.
Each of the three traces can be made visible by pressing their
respective “visible” buttons. The active trace can be peak
held by pressing it’s “hold trace” button.
