SAFETY PRECAUTIONS
The following are general safety precautions that are not related to a particular test or procedure. These are
recommended procedures that all personnel must apply during operation and maintenance. The operator must
have general knowledge of electrical theory and the dangers associated with it.
1. Before performing any series of tests, thoroughly read and understand all procedures before performing them.
2. The various SDR-OMNI connectors, switches, and controls can be located by referring to Chapter 3.
3. Take the time to learn the proper operation and function of the SDR-OMNI. Complete knowledge of the Test
Set and its capabilities greatly reduces the time it takes to complete the tests.
4. Pay particular attention to WARNINGS, CAUTIONS, and NOTES and that may accompany some test and
operational procedures.
5. Observe all standard safety procedures when working with live voltages. The potential for electric shock
exists any time the SDR-OMNI is removed from its case.
6. DO NOT service or adjust the unit alone. Always be in the presence of another person when working with live
voltages.
7. Thoroughly inspect the equipment and the local area for potential hazards. Loose clothing and jewelry should
be removed anytime the test set is being utilized or serviced.
8. Be familiar with general first aid procedures and Cardiopulmonary Resuscitation (CPR).
9. Ensure the test equipment and tools you use are in good operational condition and not damaged in any way.
10. Use only approved replacement parts. Failure to use factory approved parts may cause damage to personnel,
the test set, and possibly void the warranty.
WARNINGS
WARNING
An operating procedure or practice that, if not correctly followed, could result in
death or personal injury.
CAUTIONS
CAUTION
An operational procedure or practice that, if not followed correctly, can result in
damage to or destruction of equipment.

NOTES
NOTE
An operating procedure or condition that requires emphasis.
ELECTROSTATIC DISCHARGE (ESD)
The SDR-OMNI internal parts are ESD sensitive. An ESD may damage integrated circuits or semiconductors
located within the SDR-OMNI. Only qualified personnel should service the SDR-OMNI to prevent damage. While
performing tests or maintenance, users must adhere to the following guidelines to avoid ESD. These guidelines
are meant only as a reminder; users must consult local directives and follow standard operating procedures
before servicing or repairing the SDR-OMNI.
•Wear a properly grounded wrist strap and remain in contact with an approved grounding point.
•Do not touch the connector pins or backplanes of ESD Sensitive circuits or parts.
•Ensure soldering irons are grounded before use.
•Do not remove any components or disconnect any connectors located in the SDR-OMNI with the power “ON”.
•Properly ground all test equipment being used. Refer to the test equipment operating manual for information.
•Place all removed components or parts in or on an approved conductive package.
Most ESD devices or circuits and common points are readily identified using several different methods. See
Figure 1 for example ESD labels.
Figure 1. Example ESD Labels
The European Conformity (CE) (International Electric Commission (IEC)) marking symbols may be used in
different locations throughout the manual and are also located on and in the SDR-OMNI. Observe these warnings
and markings and follow standard electrical safety anytime you use live circuits. See Figure 2 for example
markings.

CHAPTER 1 INTRODUCTION
1.1 SCOPE
This manual is intended to familiarize the user with the operating procedures necessary to properly use the SDR-
OMNI Avionics Test Set.
1.2 FEATURES
The SDR-OMNI is a lightweight, software-defined radio frequency (RF) test set for testing RF avionics in the 200
kilohertz (kHz) to 1.6 gigahertz (GHz) range. The SDR-OMNI is designed to test all basic navigation and
communications avionics functions common to modern civil and commercial aircraft, with provisions for certain
military avionics test requirements.
It uses software defined signal processing to test complex avionics navigations and communication signals.
The SDR-OMNI can be powered by either battery or AC adapter. The SDR-OMNI includes a lithium-ion (Li-Ion)
battery that lasts 6 hours with continuous operation or 24 hours on a 20% duty cycle. The SDR-OMNI also
includes an AC adapter (100-240 Volts AC (VAC), 47-63 hertz (Hz)) that can power the device and charge the
battery.
1.3 COMPLIANCE
This Product Meets or Exceeds the essential requirements of applicable European Directives as follows:
•EN 55022, B
•EN 61000-4-2, L2&3, B
•EN 61000-4-4, L2&3, B
•EN 61000-3-2, A
•EN 61000-4-3, L3, A
•EN 61000-4-6, L3, A

2.2.1 Transit Case
The Transit Case (Figure 2-1) safely stores the SDR-OMNI and its accessories while they are not in use. The
Transit Case can be carried using the carrying handles, or the Transit Case can be rolled using the two wheels
and extendable handle. The Transit Case can be secured shut with two latches.
Additionally, four metal grommets can be used to secure the Transit Case shut with zip ties or locks (not
included). The Transit Case cover has a rubber gasket to prevent water from entering the Transit Case. The
Transit Case has a foam lining and a tray insert to organize and protect the SDR-OMNI and its accessories.

2.2.2 AC Power Adapter/DC Charger
The AC Power Adapter/DC Charger (24 Vdc) (Figure 2-2) charges the battery and supplies power to the unit for
operation. See Table 8-2 for power specifications.
Figure 2-2. AC Power Adapter/DC Charger (24 Vdc)
2.2.3 Telescopic Antenna
Most HF/VHU/UHF radio checks will be performed over-the-air using the supplied Telescopic Antenna
(Figure 2-3). The length of the antenna should be adjusted for the wavelength of the frequency band being tested
(refer to Table 2-2 and Table 2-3).
Many basic functional tests (such as Very High Frequency (VHF) Omnidirectional Radio (VOR), Instrument
Landing System (ILS) Localizer (LOC), Glideslope (GS), and Marker Beacon (MB)), Emergency Locator
Transmitter (ELT), Selective Calling (SELCAL), and Communication (COMM) tests) can be performed by a single
operator from the cockpit. The Telescopic Antenna can be extended out of the passenger door or the pilot’s
window. Otherwise, the SDR-OMNI should be placed 10 to 30 feet (3 to 9 meters) from the unit under test (UUT)
antenna with an unobstructed line-of-sight.
Hangars, ramp equipment, and other aircraft may interfere with test signals. If unexpected test results are
observed, first attempt to move the SDR-OMNI to a location that could minimize multi-path interference and
retest.

The L-Band Directional Antenna (Figure 2-4) has a flexible neck and guide arrows to properly position the
antenna for L-Band (Transponder, TCAS, UAT) testing. The antenna is vertically polarized, so the flat portion of
the antenna must be oriented vertically when pointing at the aircraft’s ATC, TCAS, or DME antenna.

interfering with ATC operations. It also enables the test operator to obtain much more accurate and repeatable
power and sensitivity readings, as it greatly reduces multi-path and uncertainty when compared to over-the-air
testing with a directional antenna.
A Whip Antenna Adapter is also included in the SDR-OMNI kit. It is used when testing aircraft that have a short L-
Band dipole transponder antenna. The whip adapter fits into the bottom of the TAP-OMNI, which is then placed
over the dipole antenna and clamped into place. The whip adapter serves to center the dipole antenna in the
TAP-OMNI so that the operator obtains reliable test results.
