The Gflex scanning receiver should look like the picture in Figure 1. If the contents are incomplete or the PCTEL Gflex scanning receiver appears damaged, please call the Technical Support line at (240) 460-8833.

Figure 1 - PCTEL Gflex Scanning Receiver

2.3. Options

Optional multi-technology measurements available for the PCTEL Gflex 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 base configuration: WCDMA, TD-LTE, FD-LTE, and 5G NR(FDD/TDD). Other available options include:

Enhanced Power Scan (EPS^TM) Option

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

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. 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.

5G NR Dual Polarization Measurement, 2.5 – 6 GHZ 5G NR (OP552)

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:

Frequency (GHz)	OP294 (dBi)Peak Gain	OP717 (dBi)Peak Gain
3.5	-1.13	1.7
3.7	1.77	2.1
3.8	1.07	2.1
3.9	1.08	1.9
4	-0.13	2

Frequency (GHz)	OP294 (dBi)Peak Gain	OP723 (dBi)Peak Gain

2.4. System Requirements

This section describes the system requirements for the PCTEL Gflex 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 PCTEL Gflex 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 Gflex can support two types of antennas for different requirements.

For 10MHz to 8 GHz 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 50GHz support have to be connected with a 2.4 mm male connector at the end of the cable.

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 PCTEL Gflex scanning receiver draws:

40 watts (max)

Voltage range for the Gflex 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 does 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.

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

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.

If the Gflex 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 is normally off and blinks green during data transfer.

4. Operation

This section discusses calibration, software upgrades, and integrating the PCTEL Gflex scanning receiver into the user’s test system.

4.1. Calibration

PCTEL Gflex 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 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.

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 power connection first, then the fuse, which is 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 PCTEL Gflex 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 Power Plug end from the power source. See Figure 15 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 23 - PCTEL Gflex Scanning Receiver Power Plug

Replace the fuse with an identical 10-amp fuse.

Note: Only use a 10-amp fuse (Gflex); 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.

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, (3) the antenna is connected to the wrong RF port, the application software is not mapping the scan to the correct port/antenna, 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.

8.3. Calibration Notice

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

PCTEL Gflex 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 PCTEL Gflex 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.

8.4. Return Material Authorization Procedure for the PCTEL Gflex scanning receiver

NOTICE: There are no user serviceable parts inside the PCTEL Gflex receiver. Any tampering with the components within the unit will void any applicable warranties.
