NAV-402APMKR/NAV/COMM Ramp and Bench Test Set

The NAV-402AP Test Set is designed tomeet the functional testing requirements ofCAT I, CAT II and CAT III ILS systems. Itincludes a modulated signal generator forMKR, VOR, LOC, G/S and VHF COMM testsand a variable output attenuator.Maximum output on any band is -7 dBm(0.1 V) output range is from -7 dBm to-110 dBm.

The VOR and G/S bands are eachsupplied with two crystals, and the LOC,MKR and VHF COMM bands are suppliedwith one crystal each. Variable frequencymodes allow all frequencies of all bands tobe used. All bands are frequency phase-locked at 25 kHz intervals except G/S. G/Sis phase-locked at 50 kHz intervals.

Two independent internal localizertransmitters with outputs of approximately-18 dBm at the generator output jack are

provided for simultaneous radiation of LOCand G/S signals in G/S XTL mode with LOCswitch on.

The test set includes a counter tomeasure the RF frequency of the signalgenerator in any band, the frequency ofany VHF COMM transmitter, any 0 dBmexternal frequency from 1 MHz to300 MHz, or display the selected VORbearing as a check on the VOR BRG. Thecounter time base is derived from a10 MHz oscillator with an accuracy of±0.002% from 0 to 50°C.

A power meter is included to measureCOMM transmitter power 0 - 10 W or0 - 100 W. A peak or average power switchallows COMM XMTR modulation checks,and a rear panel jack permits monitoring ofthe modulation.

A percentage modulation meteraccurately indicates modulation levels onany band 0 - 30% or 0 - 100%.

The NAV tones for modulation aredigitally derived from a 2.16 MHz crystaloscillator. The 90 Hz and 150 Hz tonesutilized for LOC and G/S modulation arephased-locked with an accuracy of 0.1degree.

By pressing a front panel switch therelative phases between the 90 and 150 Hz tones can be varied in 5 degreesteps, relative to the 30 Hz Referencesignal, for a 1 degree selected step on theVOR BRG selector.

IFF-701IFF Transponder Test Set

IFF-701The IFF-701 is an organizational

level/1ST Line, portable battery operatedtest set for testing IFF transpondersinstalled in airborne, naval or land basedplatforms. The IFF-701 may also be usedat intermediate level/2ND Line.

The IFF-701 provides a comprehensiveAUTO TEST function which allows theoperator to verify and certify the operationof MK10A, MK12, MK12/Mode S IFFtransponders with minimal interventiononce the test has been commanded.

Testing may be conducted over the airor by direct connection to the transponder.

Tests may be individually run fordiagnostic fault finding purposes during

routine maintenance.The IFF-701 is environmentally

packaged to operate in all weatherconditions.

OPERATIONSetup Menu

Three Setup Menus are used to programparameters for power and sensitivitymeasurements, test set operationalmodes, test data storage and recall.

1ST Line Auto TestThe PWR UP field in Setup #1 menu is

used to determine which autotest mode isavailable after power up. If 1st/L isselected, the 1ST LINE AUTO TEST screen isdisplayed when the AUTO TEST key ispressed.

The 1ST Line mode is used to providesimple point and press testing using ahand held directional antenna. Aratiometric test is used to confirm that ERP(Effective Radiated Power) and MTL(Minimum Trigger Level) are within passlimits. This test is independent of distancefrom the transponder antenna, over a 6 ftto 250 ft range.

When initiated with the RUN/STOP key,

this test runs through 31 discrete tests.The RUN/STOP button mounted on thedirectional antenna handle may also beused for single handed operation.

The modes tested, specific tests andPASS/FAIL limits are determined by theconfiguration selected in the CONFIGfield.

During the Mode 4 reply tests theoperator is prompted to changetransponder control panel settings, to verifythe crypto A/B code select and verify bit 1functions. The test may be configured toonly use the A code without operatorprompt.

Upon completion the 1ST LINE AUTOTEST screen displays the modes tested,the modes passed, the modes failed,ERP/MTL pass or fail, and lobing Ant yes orno (if enabled in the selectedconfiguration). The LOBING ANT field isused to display correct operation of alobing antenna RF switch, typically usedwith MK10A transponders. The DIST fieldis used by the operator to confirm theapproximate distance from the antennaunder test.

The detailed results of individual testsconducted during AUTO TEST are stored inmemory and may be reviewed by using theSELECT keys. Once selected the test maybe initiated by the RUN/STOP key, and willcontinue to run until the RUN/STOP key ispressed again.

Access to a direct connect POWER TESTis provided in 1ST Line mode and is used fortesting feeder and lobing switch losses.Access to the setup menus is prevented in1ST Line mode.

The 2ND Line mode may be enteredwhen the IFF-701 is in 1st Line mode, by atwin key press on power up.

2nd Line Auto TestIf 2ND/L is selected in setup menu #1,

the IFF-701 will power up in 2ND line mode.The 2ND LINE AUTO TEST screen is displayedwhen the AUTO TEST key is pressed.Pressing the SETUP key provides accessto the setup menus.

The 2ND Line mode provides preciseover the air ERP and MTL testing using thedirectional antenna. Range and heightparameters are entered in setup #1 menu.

This mode may be used periodically toconfirm specific installation performanceand monitor feeder/antenna deterioration.Direct connection via the RF I/O port is alsoselectable for bench operation.

The 2ND LINE AUTO TEST operation isidentical to the 1ST LINE AUTO TEST modeexcept ERP and MTL measurements aredisplayed. LOBING Configuration files areselected in setup #2 menu.

Two sets of test result may be stored innon volatile memory stores and the last setof results are held in current memory. Testresults may be down loaded to a PC orprinter for hardcopy.

NAV-750C3.18 http://www.ifrinternational.com

NAV-750CVOR/LOC/GS/COMM/MKR Bench Test Equipment

The NAV-750C provides internalgeneration of waveforms suitable fortesting Instrument Landing Systems (ILS),VHF Omni-directional Radio Range (VOR)systems, Marker Beacons and SELCALradio receivers. Avionics parameters arepresented in the same form as described inthe ICAO standards. The NAV-750C offersan ideal single instrument solution for thetesting of avionics receivers and alarmmonitors. The use of Direct DigitalSynthesis techniques ensures excellentaccuracy and stable performance under alloperating conditions.

ILSIn ILS mode, the Sum of Depth of

Modulation (SDM) of the 90 Hz and 150 Hz tones can be entered to aresolution of 0.1% AM depth. TheDifference in Depth of Modulation (DDM) isentered to a resolution of 0.01% depth fora DDM up to 20% and 0.1% for higherDDM settings. A choice of which tone is

dominant is available to the user.The 30 Hz repetition frequency of the

ILS waveform can be adjusted in 0.1 Hzsteps. For 0% DDM, additional modulationsignals can be added to the ILS waveform.

Changing between localizer and glide-slope operation is accomplished with asingle key stroke.

Marker BeaconsIn the Marker Beacon mode, signals are

generated simulating the outer, middle andinner marker beacons. A single key pressselects which marker beacon is simulated.Carrier frequency, modulation depth andmodulation frequency can be varied fromthe default settings. Using the normalcalling tones menu enables pulsed markerbeacon modulation signals to begenerated.

VORIn VOR mode, the AM depth of the

subcarrier and 30 Hz tone can beindependently set and the relative phase ofthe 30 Hz tone and the modulation tone onthe subcarrier is set by directly entering thebearing information in degrees. The VORrepetition rate of 30 Hz can be adjusted in0.1 Hz steps. For a fixed bearing,additional modulation can be applied tosimulate voice/identity signal. A To/FromBeacon key provides a rapid means ofreversing a bearing entry and accountingfor different bearing conventions.

SELCALSELCAL selective calling tone signals

are used on the radios providingcommunication between the aircraftoperator and the flight crew. The AvionicsSignal Generator provides facilities forgenerating the SELCAL codes and the

modulation signals to test the radioreceiver.

Simple OperationMajor parameters can be adjusted by

keyboard entry of data, using theUP/DOWN keys or using the rotary control.The use of a large screen dot matrix displayensures clear and unambiguous readout ofthe avionics parameters.

Instrument settings can be stored in nonvolatile memories. A sequence of testsettings can be stored and, using theexternal trigger facility, the currentlyrecalled memory can be incremented tostep through the stored test sequence.

Specification

Tone Frequencies90 Hz, 150 Hz nominal. Tone frequency may bechanged by varying the ILS repetition rate of 30 Hzin 0.1 Hz steps. Tone frequencies maintain 3:1 and5:1 relationships with the ILS rate.

DME (Distance Measuring Equipment)provides aircraft with accurate andcontinuous information of their slant rangedistance from a ground reference point.Option 10 on the 2030 series signalgenerators produce the necessary signalsrequired to test DME transponders. Theoption consists of two parts - an internalpulse generator to produce double pulses,and a linear RF modulator which producesthe required Gaussian shaping with 90% ofthe transmitted energy within a bandwidthof 0.5 MHz in accordance with EUROCAEED57. Front and rear panel connectorsprovide External Trigger input andSynchronization and Video outputs.

Simple InterfaceMajor parameters can be adjusted by

keyboard entry of data, using theUP/DOWN keys or the rotary control. Theuse of a large screen dot matrix displayensures clear and unambiguous readout ofthe avionics and DME parameters.

DME Pulse GeneratorThis provides Gaussian shaped double

pulses with variable control of pulse width,rise and fall times, pulse pair spacing andpulse repetition rate thus giving completeflexibility when defining the pulse profile.Continuous internally or externally triggeredmodes of operation are available with allparameters adjustable in both cases.

DME Pulse ModulatorThe Gaussian shaped double pulses

from the generator can be used tomodulate an RF carrier over the DMEtransmitter range of 960 MHz to 1215 MHz. Unlike a standard pulsemodulator where the carrier is enabled ordisabled by the modulating signal, the DMEmodulator is able to control the level of theRF signal at any particular time and thusproduces a constrained standardsincluding EUROCAE ED57 for DME. TheGaussian shaped pulses are identical inamplitude and shape with level accuracy of+/-0.5 dB over the range -110 dBm to+10 dBm.

MemoryAll the instrument configuration settings

can be stored within non-volatile memorylocations. These memories can betriggered via an external input or manuallyfrom the front panel in order that a test

sequence may be quickly recalled.

Output ControlThere are two additional outputs

provided, a SYNC output and a VIDEOoutput. The SYNC output is available eitherwith internally generated pulses or externaltrigger. The VIDEO output is the Gaussianshaped signal that is applied to the RFmodulator.

GPIB ProgrammableAll functions can be controlled over the

interface bus and are GPIB IEEE 488.2compatible.

Option 6 - AvionicsDME Option 10 is a natural complement

to existing Avionics option 06 whichincludes VOR, ILS, Marker Beacons, ADFand SELCAL.

The Avionics option offers a completetest solution for the maintenance ofavionics radio receivers by providing modesof operations suitable for testing ILS andVOR systems. In addition, it providesefficient testing of marker beacons,SELCAL receivers and ADF (AutomaticDirection Finders).

In conjunction with the Avionics option,the 2030 series offers a simple solutionwhich is particularly well suited for testingthe complete avionics system -

IFR Systems Group have writtensoftware which controls GPIB instrumentsand at the same time displays relevantparagraphs from a Microsoft Wordmaintenance schedule.

One implementation of this software isused to control the IFR 2030 AvionicsSignal Generator to help test ILS monitorsat CAA-controlled airports. Simultaneously,the software displays sections from theCAAs maintenance schedule document.The ILS software runs under Windows on aPC and controls the 2030 via a GPIB

interface which can be a NationalInstruments PCIIA card for standard PCs ora PCMCIA plug-in card for portables.

The software presents the user with twowindows: the top one displays themaintenance schedule for the ILS monitorequipment (a Microsoft Word document)and the bottom one provides the monitortest control panel. Each button on the testcontrol panel is linked to a paragraph in themaintenance schedule. The softwaredisplays the relevant paragraph from themaintenance schedule while it performseach test. The user can refer to theparagraph for any supplementaryinformation.

When a test is executed, the ILSsoftware programs the 2030 to give thecorrect Frequency, DDM, SDM and RFlevels. It also prompts the user to inputreadings obtained from the monitor undertest. The results of each test are appen-ded to a results file. This file can be inASCII, Microsoft Word table format or anExcel spreadsheet and can be viewed fromwithin the ILS software. The user cansearch the file for the history of results fora particular runway. The ILS software alsoprovides an editor which allows the user tocustomize the control panel andconfiguration data.
