2.3. Options
Optional multi-technology measurements
available for the SeeGull EXflex are
described below. These options can be
installed at the time of purchase or later on
as a field upgradeable option with the
exception of OP640, CDMA/EV-DO
Holdover Option. Refer to section 9 for a
complete list of options available for the
SeeGull EXflex Scanning Receiver and their
part numbers. Please contact your PCTEL
sales or marketing representative for pricing
and delivery information.
Enhanced Power Scan (EPSTM) Option
(OP602)
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 (OP601)
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. 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, 80 or 160 kHz or 2, 4 or 8
MHz. Output data may be set to an average
of 1, 2, 4, 8, or 16 sweeps.
LTE Power Analysis (OP632)
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
(OP620 All Layer 3 Options)
(OP620-GSM)
(OP620-WCDMA)
(OP620-FD-LTE)
(OP620-TD-LTE)
(OP620-TD-SCDMA)

SeeGull®EXflex®Reference Manual
PCTEL, Inc., RF Solutions Page 9 Revision F
Layer 3 decoding is available for LTE FDD,
TD-LTE, GSM, UMTS [WCDMA/HSPA(+)]
and TD-SCDMA technologies. This option,
provides decoding for:
GSM BCCH (Broadcast Control
Channel) messages
UMTS [WCDMA/HSPA(+)] BCH
(Broadcast Control Channel) Type 3
messages
In the GSM BCCH, types 1, 2, 3, 4, 9, and
type 13 messages are supported. For
WCDMA, TD-SCDMA and LTE, transport
block from the scanner enable support of
the Master Information Block (MIB) and
System Information Blocks (SIBs).
In the UMTS [WCDMA/HSPA(+)] BCH, the
MIB and SIBs 1, 2, 3, 5, 7, 11 and 19 are
available.. In the TD-SCDMA the MIB and
SIBs 1, 3, 5, 5bis, 7, 11 and 19 are
available.
In the GSM BCCH,UMTS
[WCDMA/HSPA(+)] and the TD-SCDMA
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).
The LTE BCCH layer 3 option conveys
system information about the cell. These
transport blocks 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 EXflex supports scanning of
numerous GSM and LTE BCCH,andUMTS
[WCDMA/HSPA(+)] and TD-SCDMA BCH
channels during the same test.
GSM C/I Option (OP631)
A C/I option is available for the GSM
SeeGull EXflex Scanning Receiver. This
option provides co-channel interference
(C/I) measurements as well as decoding of
BSIC (Base Station Identification Code).
CDMA/ EV-DO Holdover Option (OP640)
The Holdover Option enables users to
collect measurements even when a GPS
signal is not present for CDMA/EV-DO
technologies. This option maintains the
stability of the internal clock for a greater
period in the absence of the GPS signal
(normally the GPS signal is used for this).
Examples include indoor applications,
driving through tunnels or in urban areas,
where maintaining GPS (which is used by
the EXflex scanning receiver for both
location and timing) is difficult. (See Section
3 Operations for more details.)

4. Operation
This section discusses calibration, software
upgrades, and integrating the SeeGull
EXflex scanning receiver into the user’s test
system.
4.1. Calibration
SeeGull EXflex scanning receivers are
calibrated at the factory. The calibration
data is stored in the internal non-volatile
memory for each 1 dB step for the whole
input signal dynamic range. Recalibration is
recommended every year in order to
maintain the specified accuracy levels.
Please refer to the Calibration Notice in
Calibration section for more information.
Re-calibration is available as an optional
service from PCTEL Inc., RF Solutions.
4.2. Software Upgrades
SeeGull EXflex scanning receiver stores the
application program in internal non-volatile
memory, and accordingly, is capable of
being upgraded via software. Upgrades
may be needed to incorporate new features
or bug fixes. Please note that some
upgrades can only be performed at
PCTEL’s factory.
4.3. Controlling the Scanner and
Acquiring Data
A unit is controlled, and the measurement
data is received via the USB data cable.
Control of the SeeGull EXflex scanning
receiver is dependent upon the PC software
in order to collect data coming from
measurements taken from the SeeGull
EXflex scanning receiver.
4.4. Holdover Option Operation
When a GPS signal is present, CDMA and
EV-DO technologies use the GPS data for
timing information to decode the signals.
With the Holdover option, the SeeGull
EXflex will continue to accurately decode
the pilots and cell IDs for a period of 4 hours
in the absence of any GPS signal. To get
the best performance of the Holdover option
during indoor measurements, we
recommend that the GPS be locked for at
least 30 minutes before using the SeeGull
EXflex scanning receiver in an unlocked /
holdover mode (with power maintained).
Note: It is highly recommended to have the
SeeGull EXflex Scanning Receiver
recalibrated every year.

7. Troubleshooting
This section describes a few suggestions for
several common problems that might occur.
These suggestions are user serviceable.
7.1. No Power: Receiver LEDs not
Illuminated
If the SYS LED located on the face of the
scanning receiver is not illuminated, please
check the connection first, then the fuse,
which is located in the cigarette lighter end
of the power cord.
The fuse can be “blown” by a surge in the
portable or mobile battery system. A
temporarily shorted wire can also cause
other problems.
If the fuse is not operating normally, it will
open up, thereby disconnecting the input
power from the SeeGull EXflex Scanning
Receiver. The fuse is the first line of
defense should any short circuit, large
spike, or other problems occur within the
power wiring circuitry. When the fuse
“blows”, there will be no power to the
receiver.
7.2. Changing the Fuse in the Power
Plug
If it is necessary to change the fuse in the
power plug, remove the cigarette lighter
plug end from the power source. See
Figure 13 for an illustration of the power
plug.
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 13 - SeeGull EXflex Scanning Receiver
Power Plug
Replace the fuse with an identical 3-amp
fuse.
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.
7.3. Received Signal Strength Appears
Low
If the received signal strength appears to be
lower than expected, it is likely that (1) an
incorrect antenna is being used, (2) an
antenna is not properly connected or (3) the
antenna or antenna cable is damaged.
Check that the antenna is properly
connected to the scanning receiver, and
that the antenna is of the correct frequency.
Note: Do Not Use Tools to Tighten.
Note: Check The Fuse in the Cigarette
Lighter Plug First!
Note: Only use a 3-amp fuse (EXflex); 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.

8.3. Calibration Notice
SeeGull EXflex Scanning Receiver is
calibrated at the factory. The calibration
data is stored in the internal non-volatile
memory in 1 dB steps for the whole input
signal dynamic range. Recalibration is
recommended every year in order to
maintain the specified accuracy levels. Re-
calibration is available as an optional
service from PCTEL RF Solutions Group.
The SeeGull EXflex Scanning Receiver is
calibrated for several sources of variations
including amplitude levels, ambient
temperature, input frequency, and internal
noise levels for narrow and wide channel
bandwidths. The calibration parameters are
stored as single values or arrays in the
scanning receivers’ non-volatile memory.
Automated test and calibration stations use
proprietary software which performs the
process with no or minimum human
intervention. The calibration process is
followed by a fully automated production
test. The test results are stored in a central
quality database and they are extracted and
used for periodic quality audits.
Every unit that passes the calibration and
test process successfully receives a
Certificate of Calibration. This Certificate is
shipped back with the unit.
The complexity of the calibration process
precludes field calibration. It is highly
recommended that PCTEL’s scanning
receivers be returned to the factory annually
to maintain the units’ exceptional
measurement capability.
