SECTION 1 - DESCRIPTION
1. GENERAL DESCRIPTION AND CAPABILITIES
1.1 DESCRIPTION
The NAV-402AP-3 is a Bench and Ramp Test
Set designed to meet the electronic
functional test requirements of Category I
and Category II ILS Systems, Communication
(COMM), Navigation (NAV) and Marker (MKR)
Systems.
The NAV-402AP-3 contains features to allow
testing of sophisticated autopilot systems.
These features include: automatic LOC DDM,
automatic sweep, two fixed VOR frequencies;
and two fixed, paired LOC and G/S
frequencies.
1.2 FUNCTIONAL CAPABILITIES
The NAV-402AP-3 has the following features
and capabilities:
O Signal Generator with a variable
attenuator which can be connected to the
equipment under test by a radiated signal
from a self-contained antenna or by a
coaxial cable. The signal generator can
be operated under either fixed frequency
control or in variable frequency mode in
each band.
O A built-in modulation meter measures
Signal Generator Percent of Modulation
on any frequency band from 0-30% or
0-100%. Front Panel controls permit
quick setting of modulation percentages.
90° bearing check monitor allows quick
verification of basic VOR bearing from the
VOR demod signal. NICAD battery and
built-in charging system permit completely
portable operation for up to 2 hours
continuous duty. Any time the Test Set is
plugged to an ac line, the battery is being
charged. In battery operation, an
automatic timer turns the Test Set off
after 6 to 10 minutes. The Test Set can
be recycled by pressing the PWR/BAT
Switch to the BAT position.
O The generator can be modulated
internally by a 1020 Hz Ident Tone,
Marker, VHF Omnidirectional Range
(VOR), Localizer (LOC) or Glide Slope
(G/S) Tones.
O A six-digit counter which indicates the RF
of the signal generator on any band, the
frequency of a COM Transmitter under
test, any external signal input from 1 MHz
to at least 300 MHz, or the VOR Bearing
selected by the Bearing Select Switches.
O A built-in RF power meter measures COM
Transmitter power, from 0-10W or
0-100W, either peak or average power by
selecting a switch position located on the
Front Panel. A COM Transmitter
demodulation output permits viewing or
listening to COM modulation.

SECTION 2 - OPERATION
1. INSTALLATION
1.1 GENERAL
The Test Set is powered by an internal battery.
The Test Set contains a battery charging
circuit which enables the operator to recharge
the battery when connected to ac power.
NOTE: The Test Set can operate continuously
on ac power for servicing and/or
bench tests.
Refer to 1-2-2, Figure 2 for location of
controls, connectors or indicators.
1.2 BATTERY OPERATION
The internal battery (NICAD) is equipped to
power the Test Set for two hours of continuous
use, after which time, the Test Set battery
needs recharging.
The 0 to 30% scale displays battery voltage.
Normal battery charged condition is indicated
as 15 V or greater. Less than 12.5 V indicates
a discharged battery. An automatic low
voltage cutoff circuit turns the Test Set OFF
when the battery voltage drops under 12.5 V.
The Test Set contains an automatic time-out to
conserve power. An automatic timer turns the
Test Set OFF after 6 to10 minutes (only when
using battery power). The Test Set can be
recycled by pressing the PWR/BAT Switch to
the BAT position.
1.3 BATTERY CHARGING
The battery charger operates whenever ac
power is applied to the Test Set. The battery
should be charged every three months
(minimum).
NOTE: Overnight charging is recommended.
1.4 SAFETY PRECAUTIONS
The following safety precautions must be
observed during installation and operation.
Aeroflex assumes no liability for failure to
comply with any safety precaution outlined in
this manual.
1.4.1 Complying with Instructions
Installation/operating personnel should attempt
to install or operate the Test Set only after
reading and complying with instructions
contained in this manual. All procedures
contained in this manual must be performed in
exact sequence and manner described.
1.4.2 Grounding Power Cord
WARNING: USE OF A THREE-PRONG TO
TWO-PRONG ADAPTER PLUG
CREATES A SHOCK HAZARD
BETWEEN THE CHASSIS AND
ELECTRICAL GROUND.
For ac operation, the power cord, equipped
with standard three-prong plug, must be
connected to a properly grounded three-prong
receptacle.
It is the customer’s responsibility to:
O Have a qualified electrician check
receptacle(s) for proper grounding.
O Replace any standard two-prong
receptacle(s) with properly grounded threeprong receptacle(s).
1.4.3 Operating Safety
Due to potential for electrical shock within test
equipment, the Chassis Assembly must remain
installed in the Case Assembly. Battery
replacement must only be performed by
qualified service technicians.
1.4.4 CAUTION and WARNING Labels
Exercise extreme care when performing
operations preceded by a CAUTION or
WARNING label. CAUTION labels appear
where possibility of damage to equipment
exists. WARNING labels denote conditions
where bodily injury or death may result.
