SECTION 1 - DESCRIPTION
1. GENERAL DESCRIPTION AND
CAPABILITIES
1.1 DESCRIPTION
The NAV-402AP 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 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 has the following features
and capabilities:
● 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.
● 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.
● 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.
● 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.
● 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.
● A 90°bearing check monitor allows
quick verification of basic VOR bearing
from the VOR demod signal.
● A 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.
