als and workmanship to the original purchaser. Products returned for warranty service will be
repaired or replaced at Optoelectronics’ option.
Specifically excluded are any products returned under this warranty that upon examination, have
been modified, had unauthorized repairs attempted, have suffered damage to the input circuitry from
the application of an excessive input signal, have suffered damage to the charging circuitry or inter-
nal batteries from the application of excessive voltage, or show other evidence of misuse or abuse.
Optoelectronics reserves sole right to make this determination.
No other warranties are expressed or implied, including but not limited to the implied warranties of
merchantability and fitness for a particular purpose. Optoelectronics, nc. is not liable for consequen-
tial damages.
WARRANTY
Products under warranty must be returned, transportation prepaid, to Optoelectronics’ service center.
All parts replaced and labor performed under warranty are at no charge to the customer.
NON-WARRANTY
Products not under warranty must be returned, transportation prepaid, to Optoelectronics’ service
center. Factory service will be performed on a time and materials basis at the service rate in effect at
the time of repair. A repair estimate prior to commencement of service may be requested. Return
shipping will be added to the service invoice and is to be paid by the customer.

This manual covers connection and operating instructions for the
Optoelectronics Digital ScoutTM. The Optoelectronics Digital ScoutTM is
covered under U.S. Patent Number 5,471,402 and other patents pend-
ing.

WARNING - aximum input voltage is 12VDC. Automotive voltages may exceed 12V caus-
ing damage to internal circuitry. Damage resulting from excessive input voltage is readily appar-
ent and will not be covered under warranty. Units returned for warranty service that have damage
resulting from excessive supply voltages will incur service charges.
WARNING - aximum antenna input signal is +15dBm (50mW). Under no circumstances
should the Digital Scout be directly connected to an RF transmitter or be used in close proximity
to a radio transmitter of more than 5 watts. Damage to the input amplifier circuitry is readily
apparent and will not be covered under warranty. Units returned for warranty service that have
damage to the input circuitry will incur service charges.

ntroduction
1
The Digital Scout is the latest advancement in hand-held test equipment by Optoelectronics, nc. The
Digital Scout is the first nearfield device capable of detecting digital RF. The Digital Scout is able to
detect digital signals with a minimum pulse width of 300uS. These type signals include but are not nec-
essarily limited to TDMA, GSM, On/Off keying, APCO 25, TETRA and Frequency Hopping Spread
Spectrum. The Digital Scout is also capable of detecting analog RF. The Digital Scout will not detect
CDMA/Direct Sequence Spread Spectrum.
Another unique feature of the Digital Scout is its ability to display a calibrated signal strength reading
of a nearby transmitter in dBm. This allows for an accurate display of the nearfield RF strength from
-5 to -45dBm. A bargraph is also displayed as a reference. This is very useful in determining the loca-
tion of a wireless transmitter. t may also be helpful in the field in determining problems with hand held
or mobile radios.
The Digital Scout is more than a test instrument in the traditional sense because it is useful for finding
frequencies being used for two way radio communications. Up to 1000 unique frequencies can be
stored in memory, along with up to 65,000 hits on each frequency. The counter circuitry produces a
coherent and stable count when there is a single dominant signal 15 dB stronger than any other signal
in the RF floor. An embedded microprocessor evaluates each measurement statistically to determine
when an actual frequency is dominant. This is the digital filter processing which makes automatic cap-
ture and recording possible.
The Digital Scout also incorporates the feature that was patented by Optoelectronics nc., Reaction
Tune. This unique feature allows the Digital Scout to automatically tune a compatible receiver to the
frequency it captures (analog only), allowing the user to instantly monitor the signal captured.

ANTENNAS
The small dual band VHF/UHF, DB32 antenna, is a very good multi-purpose antenna capable of pick-
ing up a wide range of frequencies from 100MHz to 2GHz.The BB85 VHF/UHF rubber duck antenna
is also cable of picking up a wide range of frequencies from 100MHz to 2GHz. There are other anten-
nas available that are useful for specific frequency ranges.
RD27 26-150MHz
RD150 144-165MHz
RD440 440-480MHz
RD800 500MHz-1GHz
RD2400 2400MHz-2500MHz
CellLock 824MHz-2GHz
TA100S 100MHz-600MHz
FILTERS
The N100 FM broadcast notch filter will remove the influence of local FM stations (88-108MHz), pro-
viding up to 30dB of attenuation.
SERIAL DATA INTERFACE
The Digital Scout incorporates an RS232 interface for the purpose of interfacing to a PC. The fre-
quencies saved to memory may be downloaded using the Digital Scout download program. The Digital
Scout may also log frequencies to the PC in real time using the Digital Scout datalogging program. The
CBDS is required and includes the cable and DOS download/datalogging software.
Antenna and Accessory Recommendations
13
The Digital Scout is similar to other nearfield devices in the way it locks onto RF signals. t is looking
for a dominant nearfield signal that is 15dB above the background RF level. As it detects a dominant
signal a frequency is displayed.
Background RF levels have a large impact on how far away the Digital Scout can lock onto signals.
The higher the background RF levels the closer the Digital Scout will need to be to detect a signal. The
lower the background RF the further the Digital Scout can be to detect a signal. For instance, when in
a metropolitan area the background RF levels are much higher than in a rural area. Therefore, a 5 watt
UHF radio that can be detected from around 200 feet in a normal RF environment may well need to be
within 100 feet or less in a high RF environment. High power transmitters such as FM stations, TV sta-
tions, Paging towers and more have an adverse influence on the way a frequency counter works. Even
if the Digital Scout does not lock onto and display the frequency of your local radio station that does
not mean that it is not influenced by the RF. The RF is still present and until eliminated will continue
to have an adverse influence on the counter. Using the Optoelectronics N100 FM notch filter is a great
way to counteract the RF from FM stations. This is not to say it will not work in high RF areas, how-
ever it is something that you should be taken into account. Using different antennas also plays a large
role in the effectiveness of the Digital Scout. Experiment with different antennas for different applica-
tions and you will be surprised at the varying results.
Finally, the Digital Scout is a very unique instrument. There are no devices in the world like the Digital
Scout. The Digital Scout is capable of detecting many different digital signals, however it will not
detect any signal that has a pulse width less than 300uS, and this includes CDMA/Direct Sequence
Spread Spectrum.
