CHAPTER I
INTRODUCTION
SECTION A
This manual is intended to familiarize the operator with the operating and maintenance
procedures necessary to utilize the TR-220 Multifunction Test Set. Here-in after known as the
T/S, Test Set, or TR-220.
Figure 1-1
The TR-220 Test Set tests airborne ATCRBS, MODE A/C, and MODE S transponders, TCAS I/II
systems, DME equipment, and ADS-B and TIS Transponders. It is self-contained and battery
operated that requires no direct hardware connection to the Unit Under Test (UUT).
For transponder testing, the Test Set simulates secondary radar to receive and radiate signals to
the UUT from antennas supplied with the Test Set. For accurate power and frequency
measurements, the Test Set can be directly connected to the UUT without the use of additional
hardware.
1-1
Rev D TR-220 90 008 088-2
For TIS testing, the Test Set transmits simulated Intruder Flight Data, which is then shown on the
TIS display to verify results.
The Test Set will receive and Decode 1090 MHz ADS-B data including squitter type, airborne
position, surface position, aircraft IDENT category, Airborne velocity, Latitude/Longitude,
North/South velocity, and East/West Velocity. The ADS-B TX function allows the operator to
receive, decode, and display ADS-B squitters. The ADS-B RX function permits the operator to
simulate a 1090MHz squitter. The TR-220 can be configured to transmit an airborne or surface
position squitter containing position, altitude, velocity, heading, aircraft category, flight ID, and
Mode S address.
The simulation of an intruder aircraft converging on the Aircraft Under Test (AUT) accomplishes
TCAS testing. The simulated target will be displayed on the TCAS display so the operator can
ensure proper advisories.
DME tests simulate an aircraft at a simulated speed converging to or from a selected distance. By
comparing the Test Set displayed distance to the DME under test display, the operator can
confirm proper DME operation.
Effective April 6, 1987, The Federal Aviation Administration (FAA) has required certain tests be
performed on transponders, both conventional ATCRBS and MODE S. In preparation for the
installation of new air traffic control radar facilities, the FAA required new measurements to be
performed on existing transponders and instituted required tests for MODE S transponders. FAR
(Federal Aviation Regulation) Part 43, Maintenance, Preventive Maintenance, Rebuilding and
Alteration section has been modified to reflect current technologies and improvements. Tel-
Instruments has met all FAA requirements and recommends that the user of this type of
equipment review the appropriate FAR or contact the manufacturer of their particular model of
transponder to ensure that the current procedures and limitations are being correctly adhered to.
Eurocontrol has also incorporated new regulations for Mode S Elementary and Enhanced
Surveillance. These requirements include Selective Identifiers for high-density traffic areas and
will become mandatory beginning in May of 2003 for Elementary Surveillance and March 2005 for
Enhanced Surveillance. The TR-220 Test Set has the capability to thoroughly test these new
functions to comply with upcoming requirements. If you would like further information regarding
these requirements, visit www.eurocontrol.int/.

OPERATING INSTRUCTIONS
2.7 General
The TR-220 is a self-contained instrument comprised of a Test Set mounted in a rugged case
with a removable cover. The Test Set front panel contains all the switches necessary to test
Transponders (ATCRBS and MODE S), ADS-B and TIS, DME and TCAS equipment. By the use
of toggle switches and an easy to read display, the operator may quickly test, make accurate
measurements and perform preprogrammed or manually selected TCAS scenarios. The
directional antenna with an active LED display and optical sight are utilized for Transponder,
DME, and TCAS tests. All accessories are stored in the Test Set case for easy storage and
protection.
The TR-220 Test Set is equipped with a rechargeable Lead Acid battery, capable of operating the
Test Set using a 20% duty cycle for 8 hours at 77 degrees F (25 Degrees C). This represents a
full day of typical testing on a single charge. When operating the Test Set in lower temperatures,
the battery life will decrease slightly.
The operator will be able to utilize the Test Set until the batteries are nearly depleted. The unit
may then be plugged into a standard 115 or 220 VAC / 47 to 440 HZ power source to continue
testing. By observing a Duty Cycle (DC) of 20%, the Test Set batteries will begin regaining their
charge while testing is in progress.
The TR-220 provides a low battery warning system to alert the operator when battery strength
has been depleted to a point where testing may be interrupted. Several warning are displayed to
warn the operator of this condition and to give them a warning that the batteries will require
charging or supplemental AC power applied to complete extended testing.
As the battery capacity decreases, the Test Set will display the following:
Low Battery
Press AUTO to cont.
Toggle the AUTO switch to bypass the display and continue testing. Approximately 15 minutes of
battery capacity is available. As the battery strength decreases, the display will indicate:
Low Battery
Recharge Required!
This indicates only several minutes of testing time is available. It is recommended that AC power
be supplied to continue testing or testing halted at this point and the Test Set charged. Toggle the
AUTO switch to bypass this warning. Further testing will result in the final warning:
2-5
Rev D TR-220 90 008 088-2
Low Battery
SHUTTING DOWN
This warning cannot be bypassed, and AC power must be utilized or charging the battery is
necessary.
It is strongly recommended that the batteries be charged for a short time each week, regardless if
the Test Set has been utilized or not. A completely discharged battery will require approximately
16 hours to fully charge. Occasional charges of 16 hours on partially depleted batteries will have
no adverse effects.
Battery: EF
Cont: AUTO
To preserve battery strength, the TR-220 will automatically shut down after 20 minutes of
inactivity. By toggling any switch during the 20 minutes will reset the timer allowing
extended testing.
Standard equipment with the TR-220 is a Directional Antenna. The antenna, stored in the case
cover, can either be hand held, tripod mounted, or directly mounted on the Test Set case. The
Test Set also contains a direct connect cable for accurate power and frequency measurements
(± 2 dB) when connected directly to the UUT. The Test Set has a built in 50 dB attenuator to
prevent damage to the Test Set due to the High Power RF associated with Transponders.
The Directional Antenna is a printed circuit sandwiched between two opaque Lexan
sheets.
1. Open and remove the TR-220 Test Set case cover. Release the two (2) push button
holders
2. The Directional Antenna can be mounted on the case or be hand-held utilizing the
supplied handle.
2a. To mount the antenna to the case, simply slide the mounting Tabs (located on
the back) into the slots located on the front of the Test Set Case.
2b. To utilize the hand held method, attach the supplied handle to the bottom of the
antenna and hand tighten only.

Rev D TR-220 90 008 088-2
2c. You may also attach the antenna to a tripod, which will increase the stability due
to high winds or hand movement thus increasing the lock on rate.
3. The operator must first set the proper Antenna Gain value into the Test Set memory.
Turn the Test Set “ON” with the UUT FUNCTION switch in the SETUP position.
Locate the ANT GAIN menu by toggling the AUTO/MANUAL switch. Enter the
correct values that are affixed to the Directional Antenna (Figure 2-3) by using the
UP/FWD, DOWN/REV switch. Ensure you enter both values, 1030 MHz and 1090
MHz. Once completed, turn “OFF” the Test Set. The values will remain in the Test
Set memory. You will only need to reenter the values if the antenna is replaced or
repaired.

Rev D TR-220 90 008 088-2
7. The optical sight will have a blinking LED indicating the operator must turn the
antenna slightly to gain a strong RF signal. A steady red LED signifies a good RF
signal and the Test Set will commence testing. The operator may also observe the
TURN indicator located on the display. By slowing turning the antenna, the TURN
indicator will spin slower until a lock is obtained. At that point, the Test Set will
display the appropriate display.
NOTE: The TR-220 uses a software technique to narrow the beam width. When
testing inside of a hanger, multi-path reflections can cause erroneous TURN
indications. If unable to eliminate TURN message, remove antenna cable
connection to DIFF port. This will not affect any test results.
8. Position the antenna with an unobstructed line to the UUT antenna. Ensure that the
transmitter or receiver (RX/TX) that you are testing is significantly closer to the Test
Set than another operating RX/TX; else, an undesired reply or erroneous and
inaccurate results may occur.
2-8
Rev D TR-220 90 008 088-2
The Direct Connect Cable, supplied with the Test Set, allows the operator to conduct
transponder tests directly from the transponder under test. Utilizing the direct connect
method eliminates possible antenna and cable losses and ensures the operator the
transponder is operating at its full potential. The TR-220 has a built in 50 dB attenuator,
thus eliminating the need to connect an external attenuator for power and frequency
measurements. Simply connect the supplied cable from the test set to the transponder to
be tested. Ensure that if your transponder has multiple antennas (diversity equipped), to
terminate the second antenna to prevent damage to the transponder.
If you are not using the Direct Connect method, but the directional antenna method, you
must install the supplied termination cap on the DIRECT CONNECT port. If it is not
properly installed, the Test Set display will prompt the operator to remove the antenna.
Direct Connection
REMOVE ANTENNA
Before testing utilizing the supplied Direct Connect cable, the operator must enter the
appropriate cable loss to ensure accurate measurements.
1. Access the ANT GAIN menu by turning the Test Set “ON” with the UUT FUNCTION
switch in the SETUP position. Locate the Cable Loss menu by toggling the
AUTO/MANUAL switch. Enter the correct values that are affixed to the supplied
cable by using the UP/FWD, DOWN/REV switch. If you are using a different cable, it
is important to know the cable loss value or inaccurate results will occur. Once
completed, turn “OFF” the Test Set or toggle to AUTO switch. The value will remain
in the Test Set memory. You will only need to reenter the value if another cable is
utilized or it is repaired.
The TR-220 can be used with the (optional) TAP-200 Anti Radiation Antenna Coupler for
testing transponders (fig 2-5). The Antenna couplers provide a limited amount of
attenuation, approximately 20 dB, to prevent the transmission of the transponder signal
into the airspace above the aircraft under test. The Antenna Couplers may only be
utilized on blade type antennas.

The TR-220 Multifunction Test Set is capable of fully testing ATCRBS and Mode S, ACAS, TCAS
I, and II systems (Traffic Alert and Collision Avoidance System). The operator is able to manually
select a scenario or utilize the default scenario already preprogrammed in the Test Set Memory.
When properly used, the Test Set will simulate an Intruder Aircraft converging on the position of
the UUT. The operator may then observe the TCAS display to ensure the correct TA’s (Traffic
Advisory) and RA’s (Resolution Advisory) occur on their display.
The Simulation is used with the Directional Antenna. This gives the operator the ability to move
the Test Set to different locations and headings from the UUT.
All illustrations shown are for demonstration purposes. Though the test
NOTE results may be typical, they are not meant to replace FAA guidelines and
manufacturer recommendations.
The perimeter of the CAUTION AREA is approximately 20 to 48 seconds to the time the
intruder would enter the WARNING AREA. Refer to Figure 2-9.

The perimeter of the WARNING AREA is approximately 15-35 seconds from entering the
COLLISION AREA (not depicted).
When an aircraft enters the CAUTION AREA, a “TA” (Traffic Advisory) is issued. This
would consist of an audible and visual warning in the cockpit.
When an intruder enters the COLLISION AREA, the TCAS will issue a “RA” (Resolution
Advisory). “RA’s” consist of audible and visual warnings and possible instructions to avoid
a collision.
A TCAS display will vary dependent on the manufacturer. Typically, a TCAS I system, as
shown in figure 2-10, will display Traffic Advisories. A TCAS II System will be
incorporated with a Vertical Speed Indicator (VSI), which will issue a RA, the pilots VSI
will display a course of action to avoid a collision with an aircraft located in the
COLLISION AREA.

11. Once all parameters have been set, turn the UUT FUNCTION switch to the
TCAS position. The scenario is now held in the Test Set memory.
12. As a convenience, the following describes intruder scenarios and the correct
parameters necessary to ensure a simulated convergence will occur.
Table 2-4
To select a scenario that will properly converge and intercept the UUT, the
Aircraft altitude must be known. If any parameter is incorrectly entered, the
intruder simulation may not intersect the UUT resulting in the operator not
observing the intended display. The operator may utilize a Pitot Static Test Set to
“Pump-Up” the aircraft altitude. It is recommended that this be accomplished
before actual TCAS testing begins.
To correctly enter intruder parameters, utilize the following formula for reliable
test results.
Assume the UUT Altitude is Pumped-up to 10,000 ft, Intruder Altitude set for
20,000 ft, Intruder Velocity is 600 kts and Intruder Distance is 20 nmi.
