1. Operating Instructions
1.1 Introduction
This manual describes the operation of the iVA (Cable and Network Analyzer) developed by Kaelus.
The iVA Cable and Network Analyzer enables users to accurately measure VSWR/
Return Loss and the location of the VSWR/Return Loss faults in their RF infrastructure. The Bluetooth interface allows
unprecedented measurement exibility and opens up new & exciting possibilities in sweep testing.
The iVA is a rugged remotely controlled battery operated module that can be used with any Bluetooth enabled Android
tablet.
1.2 Functional Description
The iVA can be connected to by a tablet via an Android application available in the Play Store. The iVA is connected via
the tablets Bluetooth interface.
1.3 Features
• Rugged and reliable; designed with tower climbers in mind
• Accurate measurement of swept VSWR/Return loss and Distance to Fault (DTF) in the RF Path.
• Simplies site certication sweep testing dramatically reducing test time on site.
1.4 Specications
Please refer to the Datasheet on our webpage
1.5 Construction and Features
The external details of the iVA test set are shown in Figure 1.

(See item 3). A long touch until the Tx Rx activity LEDS ash then release will turn the iVA o󰀨.
2. Bluetooth Activity LED - Indicates when Bluetooth signaling is active
• Solid Blue indicates connected
• Flashing indicates disconnected
3. Power On/ Charge LED’s - Solid orange indicates charging. Green indicates switched on.
4. Tx, Rx Activity LED’s - Indicates when Transmit (Red led) or Receive (Green led) is active.
5. RF Input /Output Port - N Type connector.
6. USB Port - USB Port covered by a protective splashproof cover. Charging the iVA battery is done through the
USB port. Connection to your charger is done through the USB port.
7. Protective Cover - Protective cover for the RF Input Output connector.
8. Lifting Lug - Provides a fastening point for a lanyard or line to help prevent the unit being dropped, and support the
measurement head near the cable end or measurement point.
9. Protective Cover Retaining Hook - Provides a fastening point to hook on the protective cover to keep it out of the way
while connecting and making measurements.

1.7 Charging
The iVA has a non user replaceable 3.6V Li-ion battery, that is charged via the USB port.
1.7.1 Charging Constraints
There is a variety of charging currents delivered from USB Ports. Ideally your USB Port should be able to deliver 500mA
of current or more. 500mA is su󰀩cient for intermittent use at maximum operation current and charging, you may nd that
heavy continuous use will not allow you to take on extra charging with a minimal current USB port.
While long USB cables are handy for moving the iVA into harder to reach places. Low quality USB cables can reduce the
power available to charge the iVA.
The iVA will self-limit at 1.2A, and is designed to charge from a number of di󰀨erent sources. A heavy use pattern may
require the use of the supplied USB Charger.
The supplied USB charger and small USB cable is recommended for charging.
1.7.2 Charging After the Battery has Been Run Flat
The iVA has a number of protection systems to reduce the chance of battery damage from complete discharge. The iVA
hardware will prevent higher current charging of a discharged battery. If discharged, it is necessary to charge the iVA while
switched o󰀨 initially for at least 1 Hour. Note : That if the iVA has an adequate charge level remaining, normal and higher
charge rates can occur and normal use can commence immediately once connected for charging, lower current USB
charge sources may not support continuous heavy usage.
If the iVA is not going to be used for a signicant time and has been run at, it is recommended to give the iVA at least an
hours charge before storing. Li ion batteries can self-discharge at a rate of approximately 1% per month, if not used for
many months a periodic recharge may be needed.
1.7.3 Charging Time
Charging time will depend on the USB port current capacity. A new iVA, switched o󰀨 for charging with the supplied a 5V
1.2A charger can reach fully charged in approximately 3.5 Hrs.
1.7.4 Battery Life
Fully charged with continuous return loss sweeps and under Bluetooth control the iVA will last typically 3 Hrs of use. With
connect and disconnect time, rigging and installation work time a nominal 8Hr work shift is readily achieved.
1.7.5 Safety
Any attempt to replace the internal battery could damage the unit. Care should be taken to not expose the battery to high
temperatures and to not overcharge the battery.

1.8 Switching on Your iVA
A momentary touch on the Power Button with switch on the iVA. Note: the pre–use charging instructions in Section 1.7.
Turn on the iVA prior to starting the iVA application. If you have recently installed or updated the iVA Application, ensure
the iVA is charged and will be operating from a reliable power source. After initial installation or application update, it may
be necessary for the application to update the iVA rmware and download the factory calibration data. It is necessary that
the iVA and tablet can remain on until these processes have completed.
1.9 Connecting To Your Android Tablet (Application Information)
Once you have installed the Android Application there will be an icon in your applications list. Click on it to start the
program.
Figure 3 Switching on the iVA
Figure 4 Android iVA Application Icon
If the Kaelus iVA application icon is not visible on your tablet screen, check in the Apps menu. Typically the Program will
start on the devices menu screen to allow you to rst connect to the iVA, when the iVA is rst switched on the Blue LED
will be ashing, indicating that the iVA is not yet paired to a tablet.

1.9.1.1.1 Information
Displays device information. iVA rmware version.
1.9.1.1.2 Scan for Devices ON/OFF
Initially the scanning icon appears , this allows you to search for iVA’s in range. Once the Connect icon is pressed and
you connect to the iVA the scanning icon will disappear. If you want to connect additional iVA’s the Scan icon can be
pressed again to locate further iVA’s in range. It is best practice to leave the devices menu with scanning turned o󰀨. This
helps minimise Bluetooth tra󰀩c and battery consumption.
1.9.1.1.3 Connect Icons
The icon will rotate while establishing a connection to the selected iVA. The Android tablet/device will also come up with a
Bluetooth pairing message with the serial number of your selected iVA , Press OK to pair/connect to the iVA. Connection to
your iVA can be conrmed is several ways. On the tablet/device display the icon will stop rotating and be a solid/brighter
Yellow. On the iVA the Bluetooth LED will change from ashing to continuous ON. The identify function, see item 1.9.1.1.5
below can also be used.

The identify function key allows you to get a visual response from the iVA/s you are connected to in your device list
pressing will cause the blue Bluetooth, red tx and green rx leds to ash for approximately 6 seconds. This allows
you to view which is the physical device on your list.
1.9.1.1.5 Bluetooth Signal Indicator

Note: The signal icon appears while bluetoooth scanning is taking place.
Not all Android hardware provides signal strength data for the Application
to display. If your Android platform does not supply signal strength data then
the signal strength meter will not be displayed.

an update.
1.9.1.1.8 Device Search Activity Indicator
Note: The device searching function can be switched on and o󰀨 via Item 2. It is advised to leave the search function
switch o󰀨 once your iVA has been located/paired, this will improve Bluetooth data throughput and application performance
when making measurements.
