Blind Scan
The Blind Scan feature for 5G NR, FD-LTE,
TD-LTE, WCDMA, GSM, CDMA, EV-DO,
NB-IoT and Wi-Fi technologies 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.
For LTE, Layer 3 option is supported.
Bluetooth Communication
The Bluetooth Communications enables the
user to communicate wirelessly to an
Android™ device. Bluetooth requires an
antenna to operate and comes with the
scanner.

Figure 1 - SeeGull HBflex Scanning Receiver
2.3. Options
Optional multi-technology measurements
available for the SeeGull HBflex 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.
Technologies
The following Technology options are
standard on the 08910 base configuration:
GSM, WCDMA, CDMA, EVDO, TD-LTE,
FD-LTE, Wi-Fi, NR. Other available
technology options include
OP527-FD-LTE-
NB-IOT
LTE (FDD) Narrow Band IoT
Technology Option
OP527-LTE-LAA
LTE-LAA (License Assisted Access)
Technology Option
Enhanced Power Scan (EPSTM) Option
(OP608)
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 (OP607)
The built-in Spectrum Analyzer feature
provides an effective means to detect and
troubleshoot frequency-related problems.
Spectrum Analysis is also available as a

SeeGull® HBflexTM Reference Manual
PCTEL, Inc. Page 11 Rev F
package with the scanner that enables
spectrum analysis of the wide band
capability of the scanner. 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 non-averaged 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 (OP616)
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 the base station
is properly using the available resources.
Layer 3
OP615 - All Technologies (GSM, WCDMA,
CDMA, EVDO, TD-LTE, FD-LTE)
Layer 3 decoding is available for FD-LTE,
TD-LTE, FD-LTE-NB-IOT, GSM, WCDMA
and CDMA technologies. This option
provides decoding for:
•GSM BCCH (Broadcast Control
Channel) messages

2.4. System Requirements
This section describes the system
requirements for the SeeGull HBflex
scanning receiver.
Typical System
Depending on a user’s requirements,
various hardware and software components
may be used in the scanning system along
with the SeeGull HBflex scanning receiver.
However, in most cases, a typical
configuration will include a host PC
connected to the scanning receiver via a
USB cable, or Android tablet or UE
connected to the scanning receiver via a
USB cable or Bluetooth, running the user’s
application software.
Antenna Requirements
The HBflex can support two types of
antennas for different requirements.
For 10MHz to 6GHz measurements: Use a
50 Ohm impedance antenna with an SMA
male connector at the end of the cable.
For mmWave antennas: Omni antennas
designed for 24GHz to 40GHz support have
to be connected with an SMA male
connector at the end of the cable.
Power Source Requirements
Maximum power the SeeGull HBflex
scanning receiver draws:
•25 watts (max)
Voltage range for the HBflex scanning
receiver:
•9 to 17 VDC
Use a car battery, a 12-volt battery, or an
AC/DC adapter. It is imperative that the
power source be capable of supplying the
receiver with the voltage and current levels
as described above. It is HIGHLY
recommended that the power supply not
exceed the working DC voltage range of the
scanning receiver. Applying excessive
voltage to the receiver will void the unit’s
warranty.
The scanning receiver should be powered
through the power cord provided by PCTEL.
If another power cord is used, the power
cord must be one that incorporates a fuse
for protection and safety purposes or this
will void any warranties.
Software Requirements
For supported SeeGull HBflex supported
data collection software and technical
interfaces, please contact PCTEL support.
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).

3.1. Setup
The following steps explain how to connect the unit to the host PC, tablet, or UE, and power
source to begin collecting data.
1. Depending on the type of measurements to be carried out, please connect appropriate
antennas:
a. 10MHz-6GHz only: If trying to carryout measurements between the frequency
range of 10MHz to 6GHz then connect the antennas to the SMA connectors
labeled RF1 and RF2 on the unit (Figure 4). Note that for 10MHz to 6GHz
measurements RF2 is only used for these applications (otherwise, RF2 is
inactive):
i. LTE MIMO measurements enabled during eTopN scans (sub 6GHz only)
ii. When setting up scans in different frequency bands while using antennas
with different frequency ranges on the different ports (RF1 and RF2) (sub
6GHz only for technologies except 5GNR)
iii. The Signal Analyzer feature in SeeHawk Touch.
b. Both 10MHz-6GHz and 24-40GHz range: For this case, connect the antenna for
sub 6GHz measurements to appropriate RF1/RF2 port and then other mmWave
antenna to other the appropriate mmWave RF1/RF2 antenna port. Ensure that
the RF cable connector (OP306) from the mmWave DC1/DC2 is connected into
the RF1/RF2 port which is being used for mmWave measurements and not sub
6GHz measurements. See Figure 4.
2. 24-40GHz only: When carrying out mmWave measurements only (24GHz to 40GHz)
ensure that the DC1 and DC2 ports have RF cable connectors (OP306) connected to
RF1 and RF2 ports and the mmWave antennas are connected to mmWave RF1 and
mmWave RF2 ports.Connect the GPS antenna (or input) to the SMB connector.
3. If using a USB connection to a Windows laptop or tablet computer, connect the USB
cable to both the SeeGull HBflex scanning receiver (COM port) and to a PC USB port.
4. If using an Ethernet connection, the HBflex must be connected to a network or the user’s
laptop. Connect an Ethernet cable to the LAN connector on the unit.
5. If using a Bluetooth connection to connect to an Android device connect the Bluetooth
antenna to the SMA connector on the unit.
6. For Wi-Fi testing, insert the Wi-Fi Adapter (with extender) into the USB port.
7. Connect the power cable to the SeeGull HBflex scanning receiver (Figure 5) and to the
car Power Socket or to the battery pack for in-building testing. After the power switch at
the back of the unit is turned on, the SYS LED on the receiver blinks orange. After a
short delay, the light turns green (Figure 4). If the light turns dark red (either solid or
blinking), the unit has failed the power-up test. Please contact Customer Support.
8. If saving data to SD card, insert SD card into SD port. SD card use is limited to 32
Gigabytes.

The GPS LED colors indicate the following
states:
•Green: GPS module locked to GPS
signal
•Amber: GPS module unlocked Flashing
Amber: Lost GPS lock within past 5
seconds
•Red: System Error
•Purple: GPS not trained (may take up to
30 minutes and will only occur after a
software upgrade from early software
versions)
The System LED turns solid green after the
successful boot up of the system. It turns
solid red or blinking green if the boot up is
faulty. It turns blinking red if the firmware is
terminated abnormally due to an internal
error. It turns blinking amber if an
internal communication error is
detected.
The SD card LED is normally off. When the
unit is writing to the SD card it turns solid
green. If the SD card is full the LED color is
red. If the card is ejected during a write
operation and error is detected the LED
color is orange.
If the HBflex has the Bluetooth option, then
the Bluetooth LED is blue. The unit is in
discovery mode during this period. Once
another device connects to scanner
application via Bluetooth, the LED turns off
and the scanner is no longer discoverable.
After this, the LED turns off and will blink
during data transfer. When the other device
disconnects, the LED turns solid blue again.
The Com port LED blinks green during
data transfer.
4. Operation
This section discusses calibration, software
upgrades, and integrating the SeeGull
HBflex scanning receiver into the user’s test
system.
4.1. Calibration
SeeGull HBflex 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 2 years in order to
maintain the specified accuracy levels.
Please refer to the Calibration Notice in the
Support section for more information. Re-
calibration is available as an optional
service from PCTEL Inc..
4.2. Software Upgrades
SeeGull HBflex 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. Most software upgrades can
be done remotely using PCTEL’s SeeGull
Assistant. 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 for
PC, or Bluetooth for Android tablet or UE.
Control of the SeeGull HBflex scanning
receiver is dependent upon the software in
order to collect data coming from
Note: It is highly recommended
to have the SeeGull HBflex
scanning receiver recalibrated
every 2 years.

SeeGull® HBflexTM Reference Manual
PCTEL, Inc. Page 19 Rev F
measurements taken from the SeeGull
HBflex scanning receiver.
4.4. Ethernet Instructions
The Ethernet feature enables TCP/IP
communication between HBflex and a
control PC (or laptop). PC DHCP
connection is recommended for remote
access to the scanner. The user also has
the option of manually entering a Static IP
Address.
Note: If the TCP socket connection is
lost without a proper shutdown, the
scanner must be power cycled before
accepting a new connection.
Ethernet Using DHCP
Using this method, an IP address, Subnet
mask, and Gateway are acquired on the PC
automatically from a DHCP server. The
scanner is then assigned a corresponding
IP address with identical Subnet mask using
SeeGull Assistant. Make sure the selected
IP address for Scanner is not in use or
duplicated.
