2. Overview and System
Requirements
This section describes the SeeGull MX
Scanning Receiver, including the applicable
system configuration and software
requirements.
2.1. General Description
The SeeGull MX Scanning Receiver (Figure
1) is a tool for signal strength and
modulation measurement, engineered for
the rigors of mobile network testing during
planning, installation, and maintenance of
wireless networks. It supports up to six
protocols with either 4 or 8 band-designated
receive antenna (RX) ports.
Figure 1. SeeGull MX Scanning Receiver
The USB communication link allows the
host to control the operation of the scanner
and to receive measurement results. (Refer
to Section 4 for more details).
Initial Inspection
Upon receipt of the scanning receiver,
inspect the shipping container and verify
that the contents are complete and match
the packing list. The receiver should look
similar to the picture in Figure 1. If the
contents are incomplete or the SeeGull MX
Scanning Receiver appears damaged,
please call the Technical Support line at
[phone].
2.2. Measurement Options
Optional multi-technology measurements
available for the SeeGull MX are described
below. These options can be installed at the
time of purchase or later on as a field
upgradeable option. Please contact your
PCTEL sales or marketing representative
for pricing and delivery information.
Enhanced Power Scan (EPSTM) Option
(OP514)
EPS Mode provides customizable power
measurements, improving flexibility and
precision over RSSI and Spectrum Analyzer
measurements for highly-tuned analysis of
individual parts of the RF signal. EPS
features include:
Absolute Time Stamp
Auto and Immediate Measurement
Modes
Ability to set both Time and Frequency
parameters
Measure Frequency Spans from 7.5 kHz
to 20 MHz user selectable in multiples of
2.5 kHz
Measures Time Periods from 1 chip (50
µs) to 20,000 chips (1sec)
Spectrum Analyzer Option (OP513)
The built-in Spectrum Analyzer feature
provides an effective means to detect and
troubleshoot frequency-related problems.
The Spectrum Analyzer shows a wealth of
information about the signal spectrum that is
not obtainable from the standard channel
power measurement.

SeeGull®MX Hardware Reference Manual
PCTEL, Inc. Page 5 Rev. K
The Spectrum Analyzer measures and
reports power spectral density using
frequency domain techniques (a segmented
FFT approach that ensures various
resolution bandwidths and fast update
rates), whereas RSSI measurements use
analog and digital filters to select the right
frequency band and subsequently measure
total power.
One advantage of this approach is that the
Spectrum Analyzer can analyze the fast-
changing spectrum of an unstable
transmitter. The RSSI measurement in this
case will most often show a normal smooth
picture, as it averages a limited set of data
over time. The Spectrum Analyzer,
however, if used with an appropriate
resolution bandwidth, will reveal erratic
signal behavior due to its fast update rate
and unaveraged data.
The user may set the resolution bandwidth
to 5, 10, 20, 40 or 80 kHz. Output data may
be set to an average of 1, 2, 4, 8, or 16
sweeps.
LTE eMBMS (OP245)
LTE eMBMS monitoring is available for FD-
LTE. These measurements verify the
correct setup by comparing collected data
on eMBMS subframes to Layer 3
messages. It verifies there are no
overlapping Area IDs and detects
synchronization problems. We provide a
custom measurement, Cluster ID, to
determine out of network interfering PCIs or
unsynchronized cell. It also verifies proper
operation and coverage for each MBSFN
CINR, RSRP, RSRQ etc.
Period, offset, # of subframes
Blind Scan Options
(OP521 All Blind Scan Technologies)
(OP521-GSM)
(OP521-WCDMA)
(OP521-FD-LTE)
(OP521-TD-LTE)
(OP521-CDMA)
(OP521-EVDO)
Blind Scan is available for LTE FDD, TD-
LTE, UMTS [WCDMA/HSPA(+)], GSM,
CDMA and EV-DO technologies. This
feature scans the selected band and
provides the active channel numbers. Blind
Scan is useful for conducting a full band
network search where prior knowledge
about active channels is incomplete or
unknown. It is also beneficial for network
benchmarking to obtain a first-glance view
of the RF infrastructure density and
configuration.
LTE Power Analysis (OP516)
LTE Power Analysis is available for TD-LTE
and provides power of the resource block
and slot of the TD-LTE frame. This enables
users to identify interference that is time
(slots) or frequency (RBs)-selective, to
obtain a snapshot of overall traffic levels,
and to determine whether base station is
properly using the available resources.
Layer 3 Options
(OP522 All Layer 3 Options)
(OP522-GSM)
(OP522-TD-LTE)
(OP522-FD-LTE)
(OP522-WCDMA)

SeeGull®MX Hardware Reference Manual
PCTEL, Inc. Page 6 Rev. K

option, provides decoding for:
GSM BCCH (Broadcast Control
Channel) messages
UMTS [WCDMA/HSPA(+)] BCH
(Broadcast Control Channel) Type 3
messages
LTE BCCH (Broadcast Control
Channel)
In the GSM BCCH, types 1, 2, 3, 4, 9, and
type 13 messages are supported. In the
UMTS [WCDMA/HSPA(+)] BCH, the Master
Information Block (MIB) and the System
Information Blocks (SIBs) 1, 2, 3, 5, 7, 11
and 19 are supported. In the GSM BCCH
and the UMTS [WCDMA/HSPA(+)] BCH,
these messages contain the Cell Identity
and Local Area Identification information
broadcast by the network infrastructure.
This information includes the:
MCC (Mobile Country Code),
MNC (Mobile Network Code),
LAC (Location Area Code)
RAC (Routing Area Code)
These messages also contain significant
information on the configuration, activity and
performance of the network. This includes
information concerning:
Neighbor list
Mobility management (handovers,
etc.)
Group and broadcast call control
GPRS mobility management,
transparent transport and session
management
Radio resource management
SMS messages
Location services
Uplink Interference parameters
(UMTS [WCDMA/HSPA(+)] only).
LTE BCCH layer 3 messages convey
system information about the cell. These
messages contain the cell identity, channel
bandwidth, mobility management
(handovers), neighbor lists, barred cells,
intra-frequency selection, public safety
messages, etc. It supports decoding of the
MIB and SIBs 1-13.
The SeeGull MX supports scanning of
numerous GSM BCCH, UMTS
[WCDMA/HSPA(+)] BCH, and LTE BCCH

2.3. System Requirements
This section describes the system
requirements for the SeeGull MX Scanning
Receiver.
Typical System
Various hardware and software components
may be used in the scanning system along
with the SeeGull MX Scanning Receiver.
However, a typical configuration will include
a host PC running the user’s application
software with a USB cable connection to the
scanner.
Antenna Requirements
Use a 50 Ohm impedance antenna with an
SMA male connector at the end of the
cable. Refer to PCTEL’s product offering
matrix in Section 9 for part number
information.
Power Source Requirements
The SeeGull MX Scanning Receiver uses
10 to 16 VDC using the cigarette lighter
cable or the 12 foot battery/fuse box cable
(measured at the battery connector) and
draws 6.0 amps (nominal) @ 12 VDC. The
maximum current rating is 10 amps. The
scanner can be powered by a vehicle
battery, a 12-volt battery, or an AC/DC
adapter. The power source must be capable
of supplying the receiver with the voltage
and current levels as above. PCTEL
HIGHLY recommends that the power supply
voltage not exceed the working range of the
SeeGull MX Scanning Receiver. Applying
excessive voltage to the receiver will void
the unit’s warranty.
The scanning receiver must be powered
through the power cable provided by
PCTEL. The power cable is equipped with
an additional tab to sense the voltage drain
of the vehicle’s battery or if the vehicle’s
ignition is turned off. This feature is called
Ignition Sense Feature and is very useful
to prevent the vehicle’s battery from
discharging if the scanner is left on when
the vehicle is turned off. In order to prevent
the scanner from draining the vehicle’s
battery, the ignition sense wire turns off the
scanner when it senses the vehicle ignition
has been off for 30 minutes or the available
power drops below the usable voltage. The
wire connects to any fuse socket on the
vehicle that has power when the vehicle’s
ignition is turned on. Note, for ignition
sense to operate, the application
software must support this feature. If
the application does not support ignition
sense, the connection of the ignition
sense wire is not required.
Use of another power cord will void any
warranties and may result in an unsafe
condition. Refer to Section 7.1 for further
details on power cord troubleshooting.
Software Requirements
Option 1:
SeeHawk
PCTEL’s SeeHawk (Figure 2), a data
collection software package, allows for
control of PCTEL’s receivers and data
acquisition without the need for users to
Note: Outdoor antennas, including those
used by other devices, should be placed a
minimum of 6 in. (15 cm) apart, with a
recommended distance of 34 in. (86 cm).
Refer to the Instructional Guide: SeeGull
Antennas for MIMO and MISO Antenna
Schemes for further details.

6. Indoor Kit Information
Deployment of wireless data services is
resulting in further increases in indoor traffic
and coverage requirements. The
measurement, enhancement and optimization
of indoor coverage are now an increasingly
important aspect of wireless engineering.
The PCTEL SeeHawk Indoor Kit comprises a
complete set of accessories that enable the
indoor use of the PCTEL SeeGull scanning
receivers. The Indoor Kit provides a cost
effective solution for evaluating existing in-
building coverage and for planning, deploying
and testing indoor coverage systems.
The PCTEL Indoor Kit provides the right
solution for indoor walk testing that enables
wireless engineers to address the three key
steps of indoor coverage assessment and
planning:
Evaluating Indoor Coverage from
Outside Networks
Planning New In-Building Networks
Coverage Validation for New or
Existing In-Building Networks
6.1. Indoor Kits
The indoor kit for the SeeGull MX consists of
a backpack (shown in Figure 13) and related
accessories for convenient indoor
measurements using the SeeGull scanning
receiver for indoor measurements. Battery life
is approximately 4 hours. The OP431 Walk Kit
consists of
Backpack

7. Troubleshooting
This section includes suggested procedures
for addressing potential user-serviceable
problems with SeeGull MX operation.
7.1. No Power: Receiver LED not
Illuminated
When the scanning receiver is turned on and
receiving power, the Status Indicator LED
located on the face of the scanner lights up. If
the scanner is not receiving power, follow
these steps:
1. Check the connection to the power
source.
2. If the connection is secure, check the
fuse, which is located in the cigarette lighter
end of the power cord. Remove the cigarette
lighter plug end from the power source. Refer
to Figure 14 for an illustration of the power
plug.
Note: Check The Fuse in the Cigarette
Lighter Plug Before Sending the Scanner
for Service
The fuse can be “blown” by a surge in the
portable or mobile battery system. A
temporarily shorted wire can also cause other
problems.
The fuse is the first line of defense should any
short circuit, large spike, or other problems
occur within the power wiring circuitry. If the
fuse is not operating normally, it will open up,
thereby disconnecting the input power from
the SeeGull MX Scanning Receiver. When
the fuse “blows”, there will be no power to the
receiver.
3. Loosen the fuse-holding finger nut by
turning it counter-clockwise until the plug
comes apart. The fuse is inside the power
plug housing and can be removed.
Figure 14. SeeGull MX Scanning Receiver Power
4. Replace the fuse with an identical 12-
amp fast blow fuse.
Note: Only use a 12-amp fast blow fuse;
any other fuse value may cause severe
problems with the unit and void the
warranty. In order not to violate the safety
approval of the receiver, the fuse must be
safety approved.
5. Insert the new fuse in the housing and
re-assemble the plug by turning the
knurled finger nut in a clockwise direction.
Tighten this nut as tight as you can with
your fingers.
Note: Do Not Use Tools to Tighten
7.2. Received Signal Strength
Appears Low
A received signal strength that appears to
be lower than expected is likely caused by
one of the following problems:
1. an incorrect antenna is being used
2. an antenna is not properly
connected
3. the antenna or antenna cable is
damaged.
Check that the antenna is properly
connected to the scanner, and that the
antenna is of the correct frequency.
