1. Overview and System Requirements This section describes the SeeGull® LX receiver, including the applicable system configuration and software requirements.
General Description The SeeGull® LX (Figure 1-1) is a dual-conversion super-heterodyne receiver that includes a Digital Signal Processor (DSP) for signal detection, demodulation, and data acquisition. It uses a control processor for control functions messaging. It was designed for the planning, installation, and maintenance of wireless networks. It is a test tool for signal strength and modulation measurement, engineered for the rigors of the mobile test equipment market.
The DSP processor controls the RF front end, including tuning to the desired channels, and acquires two channels of baseband data. Depending on the protocol and the type of measurement, the SeeGull®
LX receiver can provide the user with critical measurements for managing the quality of the network. See Figure 1-2 for details. The raw data is further processed in the DSP processor to yield the averaged RSSI (Received Signal Strength) data and the base station identifier, statistics of the signal, and various other RF measure-ments. The unit can also be customized to do various levels of protocol analysis. The serial communication link allows the host (IBM PC or a proprietary computer with an Ethernet or an RS-232 interface) to control the operation of the scanner and to receive the measurement results. The RS-232 interface comes standard with 115.2k Baud speed, but can also be factory configured for 38.4k Baud. (Refer to section 3 for more details). If the host is an IBM PC or another Windows 2000 computer, the Applications Programming Interface (API), available from PCTEL, makes writing the host software easy. An optional description known as the Interface Control Document (ICD) of the low-level serial protocol development is also available for non-PC applications. For copies of the API and/or the ICD, please contact your PCTEL sales or marketing representative.

HoldOver option for cdma2000/EV-DO The HoldOver for cdma2000 and EV-DO scanners enables users to collect measurements even when a GPS signal is not present. Examples include indoor applications, driving through tunnels or in urban areas where maintaining GPS (which is used by the scanner for both location and CDMA timing) is difficult.
Distance Based Sampling Option
The Distance Based Sampling (DBS) option (part number OP 028) is available for the SeeGull® LX scanning receiver. See Figure 1-4 for details. It provides both model tuning and optimization capability in one tool. Traditionally, two separate tools were needed for these functionalities. The DBS option is a cost-effective and user-friendly approach to distance based sampling. For more information, please contact your sales or marketing representative. The Distance Based Sampling option includes a kit containing the following:
Sensor DBS Interface Cable Magnetic Mount
GSM BCCH Decoding Option
This option is available on the GSM LX scanners and it provides decoding of BCCH (Broadcast Control Channel) type 3 messages which contain Cell Identity and Local Area Identification. These messages include MCC (Mobile Country Code), MNC (Mobile Network Code), and LAC (Location Area Code). The SeeGull® LX receiver supports numerous BCCH frequency channels.
GSM BSIC Decoding This feature is included with the GSM LX scanners. The BSIC (Base Station Identification Code) is decoded in the receiver and can be used for identifying the transmitting base station. The SeeGull® LX platform has the best performance yet regarding the detection sensitivity of the transmitting base stations.
GSM C/I Option This option is available with the GSM LX scanners and it provides co-channel interference (C/I) measurements as well as decoding of BSIC (Base Station Identification Code).
CDMA2000 Code Domain Option This option is available on the CDMA2000 LX scanners. For each RF channel, Code Domain Scan allows the determination of where the signal energy is into the code-separated channels. The Ec/Io is reported for each Code Channel in a list user, using integer values from 0 to 127.

Built-In Spectrum Analyzer The built-in spectrum analysis feature provides an effective means to detect and troubleshoot frequency related problems. The scanner measures and reports power spectral density using frequency domain techniques. Frequency span in the RF Band, resolution bandwidth (5, 10, 20, 40, and 80 kHz), and sweep averaging (1, 2, 4, 8, and 16) are adjustable.
System Requirements
Typical System Depending on a user’s requirements, various hardware and software components may be used in the scanning system along with the SeeGull® LX scanner. However, in most cases, a typical configuration will include a host IBM or compatible PC connected to the scanner via a serial cable and running the user’s application software. This configuration is illustrated in Figure 1-5.
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 6 for part number information. Power Source Requirements Use one of the following voltage levels:
+12 VDC @ 2.4 A (Tri-Band & Dual Receiver)
+12 VDC @ 1.0 A all others 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 above. It is HIGHLY recommended that the power supply not exceed the working range of the receivers. Applying excessive voltage to the receiver will void the unit’s warranty. See Figure 1-6 for the location of the power and ground pins on the RS-232 power/connector.

Software Requirements
Option 1:
Windows Based Control
If the user is planning to develop proprietary software to control the SeeGull® LX receiver using the Windows OS, PCTEL can provide your software developers with the LX Applications Programmers Interface (API) or Enhanced Interface Control Document (eICD) to communicate with the scanner.
Option 2:
If the user does not want to develop software, PCTEL’s InSite® LX, a data collection software package, can be purchased. InSite® LX (Figure 1-8) allows for control of PCTEL’s receivers and data acquisition. Contact your PCTEL sales representative for more information.
Other System Configurations In some cases, users connect the SeeGull® LX scanner to computers other than IBM-compatible PCs. In these cases, optional low-level serial communication protocol information (Enhanced Interface Control Documents, eICDs) can be furnished with the scanner. This allows the user to write the communication drivers necessary to operate their system.

3. Operation This section discusses calibration, software upgrades, and integrating the SeeGull® LX receiver into the user’s test system.
Calibration SeeGull® LX 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 section 5 for more information. Re-calibration is available as an optional service from PCTEL, RF Solutions Group. Note:
Recalibration is Recommended Every Year
Software Upgrades SeeGull® LX scanner 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.
Operation: Controlling the Scanner and Acquiring Data A unit is controlled, and the measurement data is received via the RS-232 communication link running at 115.2k Baud (factory standard) or 38.4k Baud (please request at time of order). For instructions on how to change the baud rate, please refer to the eICD, or the API. Depending on the PC software used to work with the unit, the following is applicable:
If the user incorporates the scanner into their test system running Windows 2000, use the Application Programming Interface (API) described in References, Item 1 (Preface Section). In case the user has a system that runs an operating system other than Windows, use the description of the serial interface and messages. See References, Item 2 (Preface Section).
cdma2000/EV-DO use of GPS During collection, the cdma2000 and EV-DO scanners utilize a GPS signal to provide accurate timing for measurements of Pilot Delay, Delay Spread, Pilot Number, Aggregate and Peak Ec/Io. If the GPS signal is lost, inaccuracies in these measurements may occur within minutes, unless the HoldOver option is used.
HoldOver Option Operation When a GPS signal is present, the CDMA 2000 and EV-DO scanners use the GPS data for timing information to decode the CDMA Signals. With the HoldOver option, the CDMA2000 and EV-DO scanners will continue accurate decoding of pilots for a period of 2 -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 45 minutes before using the scanner in an unlocked / holdover mode. (with power maintained).
DBS Operation If you are developing proprietary software to control the SeeGull® LX receiver, please refer to the LX Applications Programmers Interface (API) or Enhanced Interface Control Document (eICD) for how to control and use the Distance Based Sampling option.
SeeGull™ LX Manual: Troubleshooting
11 PCTEL, RF Solutions Group Rev. K
4. Troubleshooting This section describes a few suggestions for several common problems that might occur. These suggestions are user serviceable.
No Power: Receiver LED’s Not Illuminated Should there be no power displayed on the Power LED located on the face of the receiver, please check the connection first, then the fuse, which is located in the cigarette lighter end of the power cord. Note:
Check The Fuse in the Cigarette Lighter 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 SeeGull® LX Receiver. The fuse is the first line of defense should any short, large spike, or other problems occur within the power wiring circuitry. When the fuse “blows”, there will be no power to the receiver. 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 4-1 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.
Replace the fuse with an identical 10-amp, 3 AG fuse. ONLY USE a 10-amp 3 AG fuse! Any other fuse value may cause severe problems with the unit and void the warranty. 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:
Don’t Use Tools to Tighten
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 the antenna to be used with each receiver to be sure that the correct frequency antenna is being used or that one is even connected. Figure 4-2 shows a chart for PCTEL’s color-coding. Note:

Each antenna is labeled with a tag that identifies the frequency with which it is to be used (see Figure 4-3). This information must not be lost or mixed up. Verify that all the necessary antennas are included in the shipment and that each is marked. Antennas cannot be identified by length, shape, or other physical characteristics. Note: Some Receivers Require Multiple Antennas. cdma2000 and EV-DO Receivers Require
Two Antennas (RF & GPS) for Proper Operation.

Frequently Asked Questions (FAQ) PCTEL’s website provides an up-to-date list of Frequency Asked Questions (FAQ). To see this list go to www.pctel.com, click on the RG Solutions Group link, then Support, then FAQ. At the time of release of this manual the following FAQ questions were available:
SeeGull® LX FAQ
Q What would be the effects of using the scanner indoors?
A
For Top N Pilot Scan or Pilot Scan to measure Pilot Delay and Pilot Number accurately, the cdma2000 and EVDO scanners must be locked to a GPS signal. In case of measurements taken while GPS signal is lost, measurement accuracy is dependent on Clock Card Hold Over frequency stability. Pilot Number and Peak Ec/Io will be reported correctly as long as detected Pilot Delay is within peak window search limits. For indoors measurements we recommend the ‘center pilot window mode’ be used (one of the three peak search modes the scanner supports.) For other technology scanners, they are not affected by this issue and this is not a requirement.
Q
What is the difference between the "RSSI scan" and "Spectrum Analyzer" mode in the SeeGull® LX WCDMA Scanner?
A
The differences lie in the corresponding objectives and ways of implementation of the two modes. "RSSI scan" modus, on one hand, is used for obtaining average power in one of the two signal bandwidths of the scanner. Accordingly, measures are taken to ensure high accuracy and stability of the results. The Spectrum Analysis is intended to provide a tool that shows a wealth of information about the signal spectrum that is not obtainable from the channel power measurement. Using Spectrum Analysis, one can analyze a fast-changing spectrum of an unstable transmitter, as an example. The RSSI measurement in this case will
most often show a normal smooth picture, but the spectrum display, if used with an appropriate resolution bandwidth, will show an erratic behavior due to the fast update rate and lack of averaging. In terms of implementation, the RSSI measurement uses analog and digital filters to select the right frequency band and subsequently measure total power. The SA measurement uses a segmented FFT approach that ensures various resolution bandwidths and fast update rates.
Q Is the built-in GPS receiver needed for WCDMA?
A
No. As is indicated in the product documentation, the scanner will work in areas without GPS coverage, continuously. However, with the coverage, the scanner provides an absolute time-offset measurement as well as navigation data for mapping. In order to avoid any possible confusion, let us emphasize that the GPS receiver is always included in the scanner, whether or not it is being used by the customer.
Q Are the secondary sync channels also detected and measured in top N mode for WCDMA?
A Yes.
Q
For the PSCH detection you are distinguishing between "detectable" and "discernable". What is the difference?
SeeGull™ LX Manual: Troubleshooting
14 PCTEL, RF Solutions Group Rev. K
A
The difference is as follows. The "detectable" signal is a signal that is positively found in virtually every scan. The definition also implies the intrinsic step of (nonlinear) detection (decision, as in Top-N). In practice, the criterion we use is 95% probability of detection. The notion of a "discernable" signal, on the other hand, is more analog in nature. It hails from the era of CRT-based radars, where the phosphorescence of the screen served as the video integrator. The decision was made by the eye of the operator. So, averaging is inherent in this definition, as well as a relatively subjective nature of the decision. In our case, we call a signal "discernable" in the case when we can "see" the presence of the signal over noise after averaging a few scans. No threshold is being applied to the measurement before averaging, which makes this parameter suitable in the case of "Pilot Scan" (as opposed to Top-N).

Calibration Notice PCTEL recommends a yearly re-calibration of its scanning receivers. This recommendation is based on our understanding of various factors that may affect accuracy of the measurement results. The following factors have been identified as potential sources of accuracy degradation: crystal oscillators’ aging; amplifier stages’ gain drift; LC and ceramic filters’ part value change (due to aging, as an example). Although our experience has been that in most cases the units coming back for re-calibration are still well in the specified accuracy margin, in some cases re-calibration is necessary. The SeeGull® scanning receivers are 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 scanners’ non-volatile memory. At our factory floor, 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 full-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.
