IMPORTANT INFORMATION
IMPORTANT INFORMATION / PLEASE READ
Alternatively, the Blocks mode allows you to lock in an entire range of frequencies. For instance, let’s assume that you wanted to narrow
your sweep area down to 400-480MHz. The most effective way to do so is program that range of frequencies in one of the ten blocks and
INCLUDE as part of your sweep. The Xplorer still sweeps its entire frequency range of 30MHz - 2GHZ, however it will only lock onto a
signal in that range if it is present, therefore ignoring all other signals detected. Please consult the BLOCKS section of the manual for more
detailed information.
LOCKOUTS
This mode allows you to lockout individual frequencies as you desire. When initially using the Xplorer, it may be necessary to spend a few
minutes locking out unwanted frequencies. Many of these frequencies can be eliminated in the aforementioned BLOCKS mode. Those fre-
quencies that are not programmed into the blocks mode may then be immediately locked out as the Xplorer captures the signal. As you move
in to different areas it may be necessary to lock out more unwanted signals that have been introduced. Taking the time to do this in the begin-
ning will greatly enhance the performance of the Xplorer.
OTHER ENHANCEMENTS TO CONSIDER
Antennas and front end filters play a big part in the performance of the Xplorer. Not all antennas are alike and it is recommended you use
different antennas to achieve different results. Using dual and tri band antennas such as our DB32 and BB85 are great for picking up many
different types of signals. However, it is important to note that while they may work well for an entire range, they are typically better in some
frequency ranges than others. If you are sweeping for signals in a narrow bandwidth then it may be more advantageous to use an antenna
that is cut for a specific range, ie: 144-165MHz.
The N100 FM notch filter provides up to 30dB of attenuation in the FM broadcast band. As mentioned before, the Xplorer locks onto a sig-
nal that is 15dB above the background RF floor. Eliminating up to 30dB of RF from FM stations can play a big part in the success of the
Xplorer. This will allow you to lock onto signals from a greater distance, or lock onto low power transmitters that could not originally be
detected due to the background RF.
