The built-in Spectrum Analyzer feature provides an effective means to detect and troubleshoot frequency-related problems.  Spectrum Analysis is also available as a package with the scanner that enables spectrum analysis of the wide band capability of the scanner (08902-E-SPA). 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 (FDD and TDD) 2x2 and 4x2 MIMO Option (OP635)

MIMO testing is available for 2x2 and 4x2 FD-LTE and TD-LTE.  This enables users to determine the maximum throughput capability of the RF environment and the degree of correlation between the 2 base station transmission antennas for the purpose of optimizing throughput.

Satellite Compensated NTN LTE Option(OP570-LTE-CNTN)

Support for measuring LTE in non-terrestrial satellite networks assuming that satellites effectively manage Doppler shifts. The scanner can compensate for frequency Doppler shifts up to 7.5 KHz and supports measurements exclusively in eTopN mode, which can be activated by setting "SignalMode" to "Compensated NTN LTE."

In this mode, the receiver (RX) can be configured to either 1 or 2; for RX=2, users must connect a left-hand circular polarization antenna to RF1 and a vertical polarization antenna to RF2. When using two receivers, the scanner collects data from both RF ports and reports the maximum Reference Signal Received Power (RSRP) for each, along with the frequency offset for each Cell ID. However, it should be noted that MIMO parameters are not reported in RX=2 mode, and a new option is required for NTN mode.

Wi-Fi Testing (OP524-WI-FI)

The Wi-Fi Testing Option enables users to collect measurements for Wi-Fi network using one of our supported USB adapters. Measurements can be conducted on both bands simultaneously, providing detailed information about every detected network. User experience measurements include throughput for UDPO and TCP.

CDMA Holdover (08902(S) Model)

The Holdover Option enables users to collect measurements even when a GPS signal is not present for CDMA 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 IBflex scanning receiver for both location and timing) is difficult. (See Section 3 Operations for more details.)

Signal Analyzer Adapter (OP437)

This adapter for the IBflex scanning receiver simplifies it’s use in DAS head ends (and other network equipment) for activities such as commissioning and verification. See the appendix below for more details.

This option is available on FD-LTE and TD-LTE for users to accurately measure the LTE frames for cases employing Dynamic Spectrum Sharing with 5G NR. Support for DSS is also added for blind scan LTE measurements. For blind scan DSS, users can enable DSS in blind scan LTE mode if they have DSS option enabled on the scanner. This will report accurate LTE blind scan measurements assuming that DSS is available in the network. Users also have the option of enabling Layer3 in blind scan for LTE to understand if the network has DSS enabled or not. For this user should have LTE Layer3 option enabled on the scanner.

5G NR Dual Polarization Measurement, 2.5 – 6 GHZ 5G NR (OP706) 

Measurement support for 5G FR1 sub-6GHz transmission systems that are using base stations deployed with dual polarized antennas, is available. NR TopN for sub 6Ghz has been enhanced to support this measurement. The measurement using a dual polarized antenna requires users to utilize two different RF antennas to be connected to both ports on the scanner. The two RF antennas should have different polarizations. The vertically polarized antenna V-Pol needs to be connected to the RF1 port and the horizontally polarized antenna needs to be connected to the RF2 port. The gains for the antenna connected to each port are input parameters which the user has to select from the table below based on the antenna being used:

Dual Polarization measurements with NR Blind Scan and NR Mobile Blind scan is supported with below options

2.4.    System Requirements

This section describes the system requirements for the IBflex 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 IBflex 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

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 the back of this document for part number information.

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).  

Power Source Requirements

Maximum power the IBflex scanning receiver draws:

• 18 watts (max), 15 watts (typical)
• Power save mode is not recommended

Voltage range for the IBflex scanning receiver:

• 8 to 16 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 IBflex supported data collection software and technical interfaces, please contact PCTEL support.

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 IBflex 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 more 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 IBflex scanning receiver into the user’s test system.

4.1.    Calibration

 IBflex 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.

Note: It is highly recommended to have the IBflex scanning receiver recalibrated every 2 years.

4.2.    Software Upgrades

 IBflex 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 PCTEL Upgrade 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 IBflex scanning receiver is dependent upon the software in order to collect data coming from measurements taken from the IBflex scanning receiver.

4.4.    Ethernet Instructions

The Ethernet feature enables TCP/IP communication between IBflex 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 PCTEL Upgrade Assistant. Make sure the selected IP address for Scanner is not in use or duplicated.

Subnet Mask: 255.255.255.0

IP Address Note:

192.168.2 is the network identification and are identical for the PC and scanner.

The bold numbers are the host identification and cannot be identical.

4.5.    CDMA Holdover Operation

When a GPS signal is present, CDMA technology use the GPS data for timing information to decode the signals. With the Holdover option, the IBflex 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 IBflex scanning receiver in an unlocked / holdover mode (with power maintained). The 30 minutes applies to units with serial number 81607xxx or higher, or those that have the applicable modification applied by PCTEL. Contact Customer Service for more information.

4.6.   Battery

Batteries have a one-year warranty.  Warranty is determined by the date code on the battery. Faulty batteries are not returned to PCTEL.

The date code is etched into the case at the terminal end of the battery and is formatted as “IExxxxxx,” where the six digits represent a 2-digit year, 2-digit day, and 2-digit month.

For storage, batteries should be kept at temperatures below 21 °C. Extended exposure to temperatures above 45 °C (for example, inside a vehicle) may degrade battery performance and reduce service life. Batteries should not be stored in the IBflex Battery Pack for longer than one month, and they should not be stored in the IBflex Battery Pack while the pack is plugged in and charging for extended periods. For optimal longevity, batteries should be stored at approximately 20–30% charge capacity.

Under normal storage and usage conditions, the battery is expected to retain at least 75% of its initial capacity after 300 charge/discharge cycles.

Dispose of used batteries properly. Do not disassemble and do not dispose of in fire. Replace battery with PCTEL OP429 (or Inspired Energy^® model NC2040QE34) only. Use of another battery may present a risk of fire or explosion.

5.      Walk Test Kit Information

This section discusses walk test options that can be used with the scanning receivers.

Deployment of wireless data services is resulting in further increases of in-building traffic and coverage requirements. The design, testing, and optimization of indoor coverage are now an increasingly important aspect of wireless engineering.

The PCTEL SeeHawk Walk Test Kit comprises a complete set of accessories that enable the indoor use of the PCTEL IBflex scanning receiver. The Walk Test Kit provides a cost-effective solution for evaluating existing in-building coverage and for planning, deploying, and testing indoor coverage systems.

The PCTEL’s Walk Test Kit provides the right solution for “Walk Testing” that enables wireless engineers to address the three key steps of in-building coverage assessment and planning:

• Evaluating In-building Coverage from Outside Networks
• Planning New In-Building Networks
• Coverage Validation for New or Existing In-Building Networks

5.1.    Walk Test Kits

PCTEL offers a Walk Test Kit for the IBflex scanning receiver, the OP412 Walk Test Kit as shown in Figure 28.  It delivers a convenient way to carry and power the IBflex scanning receiver for in-building measurements.  The OP412 Walk Test Kit consists of:

• Carrying case
• Battery Pack w/ Battery Case (also serves as a battery charger)
• AC Power supply with US power cord

The IBflex Walk Test Pack is flexible allowing the user to carry the IBflex as a side pack or a backpack configuration. 

Note: The Walk Test Kit comes without indoor antenna(s). The Bluetooth option must be ordered separately if not already installed on the IBflex.

Figure 28 - OP412 Walk Test Kit (illustrated showing the side pack strap)

5.2.    Bluetooth Communications RF Antenna Information

The use of Bluetooth Communications requires an antenna for operation which is included with each scanning receiver.

6.      Troubleshooting

This section describes a few suggestions for several common problems that might occur.  These suggestions are user serviceable.

6.1.    No Power: Receiver LEDs not illuminated

If the SYS LED located on the face of the scanning receiver is not illuminated, please check the power connection first, then the fuse, which is located in the Power Plug end of the power cord.

Note: Check the fuse in the Power Plug first.

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 IBflex 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.

6.2.    Changing the Fuse in the Power Plug

If it is necessary to change the fuse in the power plug, remove the Power Plug end from the power source.  See Figure 29 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 29 - IBflex Scanning Receiver Power Plug

Replace the fuse with an identical 3-amp fuse.

Note: Only use a 3-amp 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.

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.

6.3.    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.

Warranty Procedures

See Return Material Authorization (RMA) Process further below.

7.3.    Calibration Notice

Note: It is highly recommended to have the IBflex scanning receiver recalibrated every 2 years.

IBflex 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 2 years in order to maintain the specified accuracy levels.  Re-calibration is available as an optional service from PCTEL. 

The IBflex 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 every 2 years to maintain the units’ exceptional measurement capability.

10.   Appendix C: NB-IoT Measurements

10.1              NB-IoT: Introduction

PCTEL is introducing a new measurement to quantify the KPI metrics of the NB-IoT network. This application note will discuss the new features of this measurement.

10.2              NB-IoT Physical Layer

The NB-IoT physical channels can be located as a stand-alone network, or they could be part of a standard LTE network in Guard-band and In-Band spectrum. Below is a representation of these signals.

Figure 30 - NB-IoT

10.3              Top N NB-IoT Signal Measurement

            Below is a list of key features of the new measurement.

• The NB-IoT carrier follows the 3GPP FD-LTE channel raster. It has a channel index value of 100 kHz. To align the NB-IoT signal with standard LTE the 3GPP standard introduces a frequency offset value from the channel raster. The values of the offset could be 0, +/-2.5 kHz and +/- 7.5 kHz. The scanner will calculate this value as explained below.
• The user must select the ‘operation mode’ to determine whether the network is stand-alone, Guard-band or In-Band.
• When the user selects the ‘stand-alone’ they must provide the channel or frequency of the NB-IoT network. In this mode the scanner calculates the frequency offset as zero.
• When the user selects the ‘In-Band’ operation mode the scanner calculates the frequency offset from the channel raster as shown in the second column of Table 1.
• When the user selects the ‘Guard-band’ mode the scanner needs additional information to calculate the frequency offset since there is a +/-7.5 kHz ambiguity as shown in column 3 of Table 2.  In this mode the user has three choices for ‘frequency offset’:
  • ‘0’: The scanner automatically calculates the offset based on the table. In case of +/- 7.5 kHz ambiguity the scanner defaults to -7.5 kHz. In that case other modes should be used. See below.
  • ‘1’: The scanner inserts +7.5 kHz offset for the channel raster.
  • ‘2’: The scanner inserts -7.5 kHz offset for the channel raster.

• The scanner provides RP, RQ, CINR, Time offset values for primary and secondary synchronization channels as well as reference signal.
• In order to monitor the standard LTE network, the user can initiate a separate eTOPN LTE measurement.
