2. Overview and System
Requirements
This section describes the SeeGull MXflex
Scanning Receiver, including the applicable
system configuration and software
requirements.
2.1. General Description
The SeeGull MXflex 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 seven
protocols with 4 band-designated receive
antenna (RX) ports.
Figure 1. SeeGull MXflex Scanning Receiver
The USB communication link allows the
host to control the operation of the scanner
and to receive measurement results.
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
MXflex Scanning Receiver appears
damaged, please call the Technical Support
line at [phone].
2.2. Measurement Options
Optional multi-technology measurements
available for the SeeGull MXflex are
described below. These options can be
installed at the time of purchase or later as
a field upgradeable option. Please contact
your PCTEL sales or marketing
representative for pricing and delivery
information.
Enhanced Power Scan (EPSTM) Option
(OP533)
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 (OP532)
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

SeeGull MXflex®Hardware Reference Manual
PCTEL, Inc. Page 10 Rev G
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 (OP546)
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, RFRP, RSRQ etc.
•Period, offset, # of subframes
Blind Scan Options

(OP534-EVDO)
Blind Scan is available for 5G NR,LTE FDD,
TD-LTE, WCDMA, 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.
Mobile Blind Scan Option (Mobile
Measurement):

Mobile Blindscan (Mobile Measurement)
combines the functionality to detect new
channels in defined Bands, known as
Blindscan, and performs additional
measurement on the identified channels. When
channels are no longer recognized, they are
removed from the monitoring channels.
LTE Power Analysis (OP537)
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.

SeeGull MXflex®Hardware Reference Manual
PCTEL, Inc. Page 11 Rev G
Layer 3 Options
(OP535 All Layer 3 Options)

2.3. System Requirements
This section describes the system
requirements for the SeeGull MXflex
Scanning Receiver.
Typical System
Various hardware and software components
may be used in the scanning system along
with the SeeGull MXflex 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 5 for part number
information.
Power Source Requirements
The SeeGull MXflex 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 MXflex 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.
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).

3.2. Setup
Follow the steps below to connect the unit to the host PC and power source before collecting
data.
1. For antenna connections, the MXflex can be operated in automated mode where the
MXflex selects which frequency are available for each port or in manual mode where the
user selects which frequencies are available for each port. In automated mode all 4
antennas need to be connected. In manual mode, the user has control over which ports
require antennas. Check the manual for your data collection application regarding
antenna configuration. Wrong setup of antennas will result in wrong measurement
result.
2. Connect the GPS antenna (or input) to the GPS SMA connector (4). An SMA to SMB
adapter is shipped in a bag labeled OP225 with the SeeGull MXflex to allow the OP034H
SMB connector on the GPS antenna to mate with the SeeGull MXflex GPS port.
3. Connect the USB data connector (2)
to a PC USB port with the USB cable.
4. Connect the power cable to the scanner’s power connector (6) and to the vehicle’s
cigarette lighter adapter. Make sure to line up the red dots on the cable and the power
connector.
5. Optionally, connect the ignition sense wire, a wire on the power cable which can be used
to sense power to your ignition. Refer Section 2.3 for further details of the ignitions
sense feature. The scanner will operate normally whether or not the ignition sense wire
is used.
6. Turn the SeeGull MXflex scanner on by moving the Indoor/Outdoor switch (5) from the
OFF position to the INDOOR or ON position. ON mode is used for normal outdoor
operation. INDOOR mode reduces the fan noise emanating from the scanner for indoor
operation.

4. Operation
This section discusses calibration, software upgrades, and integration of the SeeGull MXflex
Scanning Receiver into the user’s test system.
4.1. Calibration
SeeGull MXflex Scanning Receivers are calibrated at the factory. Recalibration is recommended
every two years in order to maintain specified accuracy levels. The date of the last calibration is
listed on a label attached to the SeeGull MXflex. Please refer to the Calibration Notice in
Section 8.3 for more information. Re-calibration is available as an optional service from PCTEL.
4.2. Software Upgrades
The SeeGull MXflex Scanning Receiver stores the application program in internal, non-
volatile memory, enabling software-based upgrades to the scanner. Upgrades may be
needed to incorporate new features or bug fixes. Please note that some upgrades can only
be performed at PCTEL’s factory.
Note: PCTEL recommends having the
SeeGull MXflex Scanning Receiver
recalibrated every 2 years.
