Precautions

WARNING: INTERFERENCE

The IPA family of Test equipment is exempt from the technical requirements of CFR47 part 15 (FCC part 15) as stated in Section §15.103 Exempted devices” for Test equipment per sub part §15.103(c). The following Notice is mandated by Law.

§15.5 “(a) Persons operating intentional or unintentional radiators shall not be deemed to have any vested or

recognizable right to continued use of any given frequency by virtue of prior registration or certication of equipment, or, for power line carrier systems, on the basis of prior notication of use pursuant to §90.35(g) of this chapter.

§15.5 “(b) Operation of an intentional, unintentional, or incidental radiator is subject to the conditions that no harmful interference is caused and that interference must be accepted that may be caused by the operation of an authorized radio

station, by another intentional or unintentional radiator, by industrial, scientic and medical (ISM) equipment, or by an

incidental radiator.”

§15.5 “(c) The operator of a radio frequency device shall be required to cease operating the device upon notication by a

Commission representative that the device is causing harmful interference. Operation shall not resume until the condition causing the harmful interference has been corrected.”

All IPA units and external parts are solely intended as test equipment and not intended for any other use by the operator. If this instrument does cause harmful interference to radio or television reception, which can be determined by turning the

equipment o󰀨 and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the instrument and receiver

• Connect the instrument into an outlet on a circuit di󰀨erent from that to which the receiver is connected

• Consult the dealer or an experienced radio/TV technician for help

WARNING: R F H A Z A R D

This series of instrument is capable of producing up to 50 Watts of radio frequency (RF) power in the 700 MHz to 2600

MHz frequency band. Users are reminded that proper precautions must be taken to minimize exposure to these RF elds

to the recommended limits. Please pay particular care to the following areas:

• Switch o󰀨 the RF power from the test equipment before removing or connecting the cables to the test port. Burns to

ngers and permanent damage to eyes can result from exposure to connectors carrying high levels of RF power.

• Ensure that any antennas being tested are placed so that no personnel are exposed to RF eld levels in excess of the maximum exposure limits [Ref ARPANSA RPS No. 3 for Australia]

Also, the unit should be operated by a suitably qualied operator in order to ensure interference is not caused to other

spectrum users. Radiation through an antenna requires authorization by the frequency license holder to do so.

1. Operating Instructions

1.1 Introduction

This manual describes the operation of the iPA (Interconnect Portable Analyzers) A&B series type of portable intermodulation test instruments developed by Kaelus. The iPA Series Portable Passive Intermodulation (PIM) Analyzer enables measurements of the PIM quality of RF components. The iPA is a fully portable battery powered test instrument, that can be locally controlled using a touch screen interface or remotely controlled via wireless connection to a computer or smart device.

The iPA Series Portable Passive Intermodulation Analyzer is predominantly used to nd IM3 sources such as badly

terminated or loose connectors and faulty components.

The IPA series portable passive intermodulation analyzer measures the PIM quality of a component by monitoring reverse

PIM uctuations whilst a component is moved, knocked or stressed in some way.

The iPA is a light, small, a󰀨ordable, highly portable, rugged, easy to use, battery powered, remote controllable, market

leading interconnect tester.

1.2 Functional Description

The iPA is designed to carry out reverse Passive Intermodulation (PIM) measurements in accordance with IEC62037. PIM

occurs in passive devices whenever two or more RF signals encounter non-linear electrical junctions or materials. The

interference generated is mathematically related to the localized downlink frequencies and can result in a noise rise in the uplink band of one or more systems sharing the RF infrastructure. The impact of PIM on the network performance can be severe, especially for wideband systems such as CDMA, UMTS or LTE. PIM interference can lead to desensitization

of the receiver causing increased dropped calls, increased access failures, pre-mature hand-o󰀨s, decreased data

transmission rates and decreased system coverage and capacity. Any component in the RF path can be the source of the PIM interference including antennas, TMAs, diplexers, duplexers, surge arrestors, cables and connectors. In addition, loose mechanical connections or rusty surfaces external to the antenna system can generate PIM when subjected to high radiated RF power.

Two synthesized carriers can be set to specic frequencies in the transmit band. With the RF output switched on, these tones will be present at the test port and stabilized to the predened output level. The resulting 3rd and 5th order

intermodulation product is automatically calculated and the receiver is tuned to the required product. The detected voltage is processed by a microcontroller and the relevant reading shown on the display unit.

1.3 Features

• Rugged and reliable; designed with tower climbers in mind

• Tablet PC included for remote control of device

• Capable of connecting to any Wi-Fi device

• 4.3” LCD touch screen for local control

• Automatic detection and shut down when high Return Loss is detected

• Spectrum monitor, frequency sweep and time trace modes

• Internal detector circuits with narrow IF bandwidth provide low noise oor

• Internal carrier power monitors

• Complete frequency agility in steps of 100 kHz to any frequency in the specied transmit bands

• Automatic internal calculation of IM product frequencies for receiver tuning

• Onboard report generation and exportation in PDF format

• All electronic systems are monitored and alarmed. This ensures that each measurement made is faultless

• An optional (RTF) Range To Fault Unit can assist to locate the point where either Return Loss or PIM may be occurring.

1.9.1 Fixed Tone

Fixed Tones mode can be displayed in two di󰀨erent forms. The iPA will always on rst load display the Fixed Tones

measurement mode in the Numerical PIM display our default measurement mode. The alternate display the PIM vs Time (sometimes called the Time Trace mode) is particularly useful for illustrating IM performance during a set time interval and under percussive testing. The measurement trace gives a “timeline view” on how the IM level changed within the set time

interval. As with the default measurement mode, the TX tones remain xed whilst the IM measurement is taken at the

corresponding IM frequency. Before the IM measurement is shown, time is allowed to stabilize the output tone powers to

within +/-0.5dB of the preset level.

The features o󰀨ered by this mode are as follows:

• A peak level marker (Yellow line) highlights the peak IM level

• The time axis is automatically scaled as per the Power Timer setting mentioned earlier

• User adjustable Pass/Fail limit line (Red Line)

• Manual Measurement recording

1.9.2 Frequency Sweep

The Swept Tones mode is particularly useful for highlighting anomalies in IM performance within a specic receive band.

The instrument measures the vector sum of all PIM sources present on an RF path. If two PIM sources of approximately equal magnitude are present on the RF path and are physically separated in such a way that the two signals arrive at the

PIM test equipment exactly 180⁰ out of phase, the two PIM signals will cancel and the PIM problem may not be evident.

Changing the test frequencies will change the generated PIM frequency and the phase relationship between multiple PIM signals on the line, if they exist. “Sweeping” across multiple test frequency combinations provides a range of data points to accurately characterize the PIM performance of the system.

With this measurement mode, the high power tones are swept across the transmit band in such a way that their IM

products fall within the receive band. To optimize speed and e󰀩ciency only those pairs of transmit frequencies which create IM products in the receive band are swept. A unique feature is the use of dual-tone sweeps: the high-frequency tone is rst swept towards the stationary low-frequency tone (Sweep:1/2) and then the low-frequency tone is swept upwards toward the stationary high-frequency tone (Sweep:2/2). The progress on any dual-tone sweep is shown by the sweep number as tagged in the gure below.

Figure 34 Swept Measurement Window

Note: The instrument will complete as many dual-tone sweeps as possible within the preset time frame. After the timer expired the RF is switched o󰀨.

Note: The test equipment automatically changes the two test frequencies and displays the resulting IM frequency, when doing the frequency sweep.

The frequency step size is adjustable and directly impacts on the time it takes for a sweep to complete. Clicking on the

frequency step label, will open a selection window with di󰀨erent frequency steps. The user can make a suitable selection

based on the IM bandwidth in question.

Figure 35 Frequency Step Selection Window

The gure below shows the IM order selection window. If a particular order IM band is present within the instruments

receive band, it will be displayed.

Operating Manual | The Battery Operated Intermodulation Test System

Figure 36 IM Order Selection Window

The user is at liberty to record the peak IM level of a test point at any time during the active frequency sweep. Alternatively, if the set measurement interval is allowed to expire, the user will have the option to save the peak result to the test report.

1.9.3 Spectrum Monitor Mode

The Spectrum Analyzer mode o󰀨ers an added analysis tool and is especially useful in detecting external interference

introduced in the instrument’s RX band. When the application starts up, a sweep is automatically initiated to detect

interferers in the RX band of the instrument. In the default state, the two TX test tones will remain o󰀨, but the user also

has the option for turning them “on”. When “on” the operator will see all intermodulation products that fall within the

receive band as well as wide band interference of whichever nature. A peak hold feature identies the worst case value

measured during each sweep.

The features o󰀨ered by this mode are as follows:

• Adjustable sweep step size

• A peak level marker highlights the peak IM level and at what frequency this measurement was taken

• The option to have the RF on or o󰀨 in this mode

12345

Figure 37 Spectrum Analyzer Measurement Window (Local Display)

An added feature in the spectrum monitor mode is the option to switch the RF on. In practical terms, this feature allows the user to see interference in the proximity of an IM signal. (Note: This feature is due to be released for the iPA at a future date).

from the iPA test set. Details on the operation of the RTF test set is given in the RTF operating manual:

R99-0068-RTF_A-SERIES_OPERATING_MANUAL_RevB.doc

Figure 38 Range to Fault (RTF) Measurement Window

1.9.5 Eco Mode

Eco Mode o󰀨ers a battery saving feature. Eco mode will power down the iPA’s instrument RF stages when not in use,

helping to extend the battery life. Remote control and hotspot functions are still active, so the user can still access all the report functions and data while the iPA is in Eco Mode. This also allows remote users to return the instrument to the measurement mode of their choice whenever it is required. In addition to Eco Mode the local instrument display has a display dimming function that can be set to operate independently saving even more battery current. Eco Mode and the display dimming functions have their own timers that can be set in the Settings/Miscellaneous menu on the LOCAL console. The iPA can be set into Eco mode immediately via the mode menu both on the LOCAL console and remotely.

Eco mode also frees up processor capacity. When generating large reports and uploading and downloading les, being in Eco mode can make these jobs nish quicker.

1.10 Generating Reports

The iPA includes industry leading report generation functions to assist system installers designers and maintainers provide a clear picture of the state of the equipment under test. Saving time for everyone involved in the process.

1.10.1 Overview

Reports can include tags or a combination of tags to identify results against equipment and cable sections that can be

saved and re-used .

Site, cable or equipment images can be uploaded directly into the report from the controlling smartphone, tablet or laptop and comments added. The ability to add both contractor name and logo on the instrument and generate a PDF report directly helps to provide not just a professional looking report but helps to identify where the reports have come from and saves time, chasing a reports origin. Measurement Plots and screens can be added to the PDF reports and commented, helping to convey the user’s view of what they are seeing in the report. Results can be recoded at various points showing IM product, power levels frequencies and spec applied. Reports can be retrieved from the instrument by either saving them on and removing the SD card or downloaded directly

Operating Manual | The Battery Operated Intermodulation Test System

2.4 iPA Client Connection Mode

2.4.1 Overview

The iPA can connect as a client to an existing wireless access point. The following aspects of it’s operation need to be considered.

1. Only WEP, WPA network security is supported, enterprise security is NOT supported.

2. Your Wireless access point needs to be set to visible with the password security protocol that is acceptable to the iPA client as mentioned in point 1. Some access points such as phones have a timer, only allowing the access point to be

visible for a short period, it is sometimes necessary to re-check the visibility check box if you have not connected the

iPA to the Access point in time. (You will need to refer to the documentation from your access point supplier to see if

it’s features are suitable and how it is congured)

3. Your network password is not stored on the iPA. Every time you connect to the access point the user password will

need to be re-entered.

4. An understanding of how your wireless access point delivers DHCP (Dynamic Host Control Protocal) is needed. It

may allocate IP addresses from a pool of addresses, can be congured to allocate a xed address, or deliver DHCP

services from it’s connected network. Connecting to your iPA can be impacted by how this service is delivered.

5. If the iPA is to be accessed via an intranet or internet you will need to consult the documentation of you access point supplier to see if NAT (Network Address Translation) , Port forwarding or network tunneling is available. Your network administrator may also need to be consulted.

6. Security. All measures should be taken to make a secure network prior to wireless access point, particularly if the access point is connected to a wider network, likewise regular password changes of the last wireless leg of the network to the iPA is also good security practice. Not having wireless access active for extended periods can reduce wireless vulnerabilities.

7. Familiarity with your wireless access points functions is needed. Having your access point’s product documentation available and/or support from the supplier will assist. Some examples are given, though this will vary depending your hardware. Check with your supplier to check your access point works before going on site.

8. The iPA is not available for use as a hotspot when in client/wi mode. Access for for the iPA and any controlling device/s will need to be arranged on the access point and their DHCP requirements met. Likewise any additional iPA client units need to be added to the external access point.

2.4.2 Enabling WiFi Client Mode

Under the settings menu select Network . Scroll down and turn on the Wi enabled switch, see item 1 below, this will also turn o󰀨 the Hotspot enabled switch.

Figure 61 Select Wi-Fi enabled (Client mode)

2.4.3 Connecting the iPA to the external wireless access point.

Ensure your wireless access point/router has been set to visible and select WiFi settings.

A list of available wireless access points will appear, select the name of the desired access point and enter the password

you have congured . Press connect

Select a

Network

Figure 62 Wi-Fi Settings, Network Selection and Password Menu

If everything is correct you should get a WiFi Connected message on the display.

Note : If connecting to 2GHz wireless LAN the internal panel antennae will be used . An external antenna will need to be

tted if you are attempting to use 5 GHz wireless LANs.

Operating Manual | The Battery Operated Intermodulation Test System

2.4.4 Establishing the IP address of your iPA

Scroll to the top of the Network menu. If you have successfully connected to the external network the name of the external network will appear and the IP address allocated to your iPA by Access Points DHCP service . You will need this address to allow you to connect to your iPA with a remote control device.

Figure 63 IP address allocated by the access point.

2.4.5 Connect your other devices

Connect any other iPA’s via the same method, note that each iPA will have it’s own IP address. Connect laptops , tablets or other control devices to the same wireless network and using the same network password . If for example I had a laptop connected to the TARDIS wireless network shown in Figure 63 above . Open Chrome Browser and type the following URL in the Browser http://192.168.0.20 . You should now be able to connect and remotely control that iPA , if there are additional iPA’s connected on the TARDIS wireless network you would simply change the IP address number to that shown on that iPA. Refer to Figure 60.

2.5 External Wireless access point examples

Note : If you don’t mind having to check what IP (internet protocol) address is allocated to the iPA, you could stop

conguring DHCP here . This conguration will allocate an address from a pool, this shows a pool of 64 addresses with

192.168.11.1 and 192.168.11.2 already used by the access point and the DHCP server. Some Access points may give you

the option to allocate a xed IP address . As shown in

2.5.3 Outside connection via wireless router

Depending on your external wireless access points capabilities there may be several ways to connect to your iPA . To connect to a single iPA most routers provide either a virtual server function or NAT (Network Address Translation) table. Consult with your Network administrator for the preferred method to use.

Figure 67 Typical NAT configuration from an intranet

Most wireless routers are congured to share a Pool of wireless side addresses with a single Intranet side address. Some

routers provide functions that allow incomming requests on the intranet side to be redirected to single IP address on the wireless side. This would then allow you to point your Chrome browser on the intranet side to http://10.22.100.100 and control the iPA on the wireless side at 192.168.0.20. Consult your wireless router provider information to establish what functions are available. Port forwarding functions may also be an option in this situation. Some routers have provision for a VPN (Virtual Private Network) this can provide a network tunnel across the internet.

3. General Detail

3.1 Getting The Best From The Test Equipment

There are a number of practices that will allow the best to be gained from the IM test system, especially for taking PIM measurements.

Connector & Cable Care

• Good quality connectors and test cables are essential for making PIM and return loss measurements

• Take good care of the RF connectors on the test port and the test cable. Do avoid damaging the connectors in transit

• Remove O-rings from all test equipment adapters and test leads. This will reduce the torque required to achieve

a tight, low PIM connection during test and extend the life of the connectors. (Do not remove O-rings from the site

jumper cables)

• Care should be taken when mating a cable to the test port on the test set. Ensure the mating surfaces line-up

correctly, and the coupling nut does not cross thread. Tighten the locking nut by hand initially, and then only do a nal torque using a spanner. If a torque spanner is used, torque the 7-16 connector to a maximum of 25 Nm; otherwise ensure that the connector is rmly fastened. DO NOT allow the body of the connector to rotate. DO NOT over-torque

these as this can cause permanent damage to the connector.

• Ensure that the relevant connectors are cleaned regularly as lack of cleanliness can cause PIM problems

• A cleaning kit is supplied within the accessories kit for this purpose. Clean connector mating surfaces using a cotton

bud and an isopropyl wipe to remove dirt, dust & small metal lings

• The connection of the cable screen to the connector is a major cause of PIM problems, so observe connector assembly instructions closely if constructing your own

• Do not allow the body of the connector to rotate while tightening

• Keep protective caps installed on RF connectors whenever they are not in use

• RF connectors have a nite life and are typically rated for 500 mate / de-mate cycles by connector manufacturers. Longer life is achievable with proper Care

Making PIM Measurements

• PIM measurements made by the test set are a󰀨ected by all items attached to the test port. This includes the test cable, the device under test and any terminations.

• Be aware that high power resistive loads are known to have poor PIM in the region of -60 to -80 dBm for two +43 dBm tones. Choice of RF load type is important and cable loads are preferred for good PIM performance.

• Not all test cables are suitable for taking good quality PIM measurements.

• All isolators and circulators are known to be a source of poor PIM performance in the region of -50 dBm for two +43 dBm tones.

• If constructing your own cables, the major sources of PIM are in the connectors, the connection of the Outer Conductor of the coax to the connector and the Outer conductor itself. Observe connector assembly instructions closely.

• PIM measurement must be taken under conditions that simulate the physical stresses that apply in the installation environment, and the recorded results can only be regarded as relevant if this stress is applied during the test sequence. International standard IEC37065 provides guidance on this matter.

General Tips and Caution

• Correctly terminate components to measure best return loss

• When not carrying out measurements, switch the RF Output Power OFF, for safety reasons

• When connecting or disconnecting from the measurement port, switch the RF Output Power OFF

Operating Manual | The Battery Operated Intermodulation Test System

3.2 Safety Features

There are several features to enhance the tester’s safety and prevent damage to the instrument. It is important that the

operator is aware of these built-in features.

1 Auto-Power O󰀨

The RF power is on a ‘Power Timer’ which is set up in the Timer menu. The maximum time the power can be on at any

time is 90 Seconds. This is an added feature to prevent power being left on for an indenite time.

2 Fuses

The iPA has a 4 Amp fuse on the internal DC bus to protect the internal circuitry. This fuse is not User Accessible.

3 Battery Over-temperature shutdown

The battery has inbuilt hardware over temperature protection. When the battery reports more than 50 Deg C, the iPA software suspends charging until the temperature drops.

4 Local Exclusive Control

On the local control panel the instrument can be set to Local exclusive control. This prevents any connected remote

control from operating the RF On Control, while changing cables and congurations.

3.3 Accessories Kits

Accessory kits are provided with iPAs and include the basic tools, cables, connectors, and adapters etc. to do PIM testing

in the eld. Users are encouraged to contact iPA service centers to discuss the specic requirements and congurations

of these accessory kits.

3.4 Handling And Transport

• The equipment is designed for rugged handling, but it remains a precision test instrument and should be handled with care

• Do ship the equipment in a padded external box where possible

• Use a lock or external straps to secure both IM tester and accessories kit

• Airfreight is allowed as there are no dangerous items contained within the iPA (but battery packs should be transported in accordance with Airline Company regulations).

• Transport via road freight is preferred to air freight due to care of handling

3.5 Cleaning The Equipment

Before commencing any cleaning, switch o󰀨 the equipment. We recommend that the exterior surface of the equipment

case is cleaned using a soft cloth moistened in water. Do not use aerosol or liquid solvent cleaners.

To prevent damage to the internal panel, care should be taken not to scratch the surface during use and also when cleaning. To prevent the access of moisture and lint into the device, we recommend that the internal panels and

instruction sheets should be cleaned by wiping with a slightly damp, lint-free cloth gently over the surface.

If the remedies indicated in the chart below do not solve the problem, consult the manufacturer for further instructions.

Power

No Power upon pressing power switch

• Insert a fully charged battery.

• If the above action does not x the problem the test set should be returned to a Kaelus/Summitek approved service facility.

• Note : Battery charging occurs when connected to the charger and the iPA is switched ON.

Operation

PIM measurements are worse than expected.

• Tester may be defective. Perform RF verication using PIM standard from accessories kit. Check PIM of an external cable load

• Conrm all test rig components are in good condition by separately testing the device or system under test

• Device under test may have poor PIM. Test a device with known PIM performance.

• RF cable may be defective. Try another RF cable or attach an external cable load directly to test port to conrm

• Benchmark against another IM tester

Carrier frequencies are not suitable for antenna feeders using Tower Mounted Ampliers (TMAs).

• Bypass TMA using cable tail with known PIM. Retest PIM

• Consult manufacturer. Other frequencies can be supplied

Carrier frequencies cause interference or regulatory problems.

• Consult manufacturer. Other frequencies can be supplied

Buttons Greyed out and not working with remote Tablet PC

• Another remote client may have control. Check the control icon to see you have control. Note : Network settings cannot be changed remotely.

• Some buttons are inhibited during certain functions, changing settings while a test is underway for example.

Unable to take control with remote Tablet PC

• Another Client or the local control screen may have exclusive control. Releasing remote control on the local control screen will take priority over any remote control sessions. This should allow you to take control again.

Geotag

• Geotag data may not be available inside a screened room or where high RF elds are present. Secure your location on your smartphone or Tablet PC before connecting wirelessly to the iPA or entering the screened environment.

• Geotag data is only as good as the information provided by the location service on your Smartphone or Tablet PC. You must allow the web browser application to access your location when prompted.

Operating Manual | The Battery Operated Intermodulation Test System

• Geotag service providers can gather geo data from several sources. Having more data sources turned on, on your

smartphone/Tablet PC being shared with your geotag service provider can improve your chances of an adequate x. These include GPS (Global Positioning System) switched on and set to share your location (if tted), Wi-Fi access

points that can be received nearby, Cellular Phone tower signals being received nearby for smartphones or phone

enabled tablets, and an internet data connection can all assist to get a geotag x.

• If your smartphone/Tablet PC Wi-Fi is your only Geotag data collection source, get your geotag x rst then use the Wi-Fi to connect to the iPA Hotspot after your location is resolved.

• You can use your map application on your Tablet PC or phone to conrm you have a Geotag x for your location this can help isolate problems with your Geotag x. If your Geotag location information is not accurate enough, or you are not yet able to get a x on your location (Green globe icon ashing), then the Geotag x will not be included in the

report or be saved in the Geotag Cache if enabled.

• If reports are showing longitude and latitude from a previously visited site this could indicate the old location is still

saved in the Geotag Cache. This can be cleared by switching the Geotag cache o󰀨 then on again, or recording a new

point with a correct Geotag location, or waiting for the Geotag Cache to clear automatically after an hour.
