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 measure Through Loss/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 iOS iPAD.
1.2 Functional Description
The iVA can be connected to by an iPAD via an application available in the APP Store. The iVA is connected via the iPADs
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.
• Simplies site certication sweep testing dramatically reducing test time on site.
1.4 Specications
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.

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 sucient 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 dierent 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 signicant 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.
Operating Manual | Cable And Network Analyzer System (iOS Version)

1.8 Switching on Your iVA
A momentary touch on the Power 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 iPAD remain on until these processes have completed.
1.9 Bluetooth Connection Via Settings Menu
In order for the iVA App to connect to the iVA, a Bluetooth connection must rst be established via the settings menu.
Make note of the serial number of your iVA and locate it in the iPAD’s Bluetooth devices menu and connect. You will then
need to allow the Bluetooth device to connect to the iVA Application. This will need to be repeated for all of the iVA’s in
use. iOS restricts the number of iVA’s that can be connected to 4 (As of Version 9.0.2) .

1.10 Connecting To Your iOS iPad (Application Information)
Once you have installed the iOS Application there will be an icon in your applications list. Click on it to start the program.
Figure 5 Allowing the iVA app via Bluetooth
If the Kaelus iVA application icon is not visible on your iPad 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 iPad.

Displays iVA’s device information and iVA rmware version.
1.10.1.1.2 Connect Icons
The icon will rotate while establishing a connection to the selected iVA. The iOS iPAD/device. Connection to your iVA can
be conrmed in several ways. On the iPAD/device App 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 3 below can also be
used.
1.10.1.1.3 Identify
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.

1.10.1.1.5 Progress Bar
Shows the progress of the transfers to and from the iVA. This could be factory calibration data or rmware (ensures your
iVA rmware is compatible with the application version you are using), and will occur on the rst use of the iVA or after
an update.
1.10.1.1.6 Enter Calibration Menu
Calibration saved Requires calibration
When the user enters any test mode (Return Loss, Cable Loss, DTF), the calibration status will be displayed and
color coded as described below. The accuracy of the iVA is quite good directly from the factory. However, it is highly
recommended that an Open-Short-Load (OSL) calibration be performed to maximize data accuracy. The Calibration
status will change depending on how much time has passed since the calibration was performed and if the temperature
has changed by more than 8 degrees since the last calibration. The table below indicates the recommended uses for the
dierent calibration states.
CAL Performed CAL Status Status Shown on Plots
and Reports
Acceptable for Use as
Follows
OSL Calibration
Last Calibrated Less than
12 Hours Prior Last Calibrated Time Prior Reportable Measurements
Last Calibrated Between 12-

General quick check and
repairs at a given
measurement plane
Last than ±8° C Temp
Change Last Calibrated Time Prior Reportable Measurements
Greater than ±8° C Last Calibrated =
Uncalibrated Fault nding and repairs
From the table we can see that once the iVA has been given an OSL Calibration, the iVA calibration indicator will remain
green for 12 Hours providing there has not been more than an 8 Degrees temperature change. The iVA can continue to be
used for fault nding and repairs and then be re-calibrated for the site report.
