Aeroflex is a leader in the design, manufacture
and marketing of Avionics test systems.

The ATC-1400A is a microprocessor-controlled
test set designed to accomplish complete test­ing of modern ATC Transponder and DME
equipment.

SIGNAL GENERATOR

Frequency Select Modes

User selectable L-Band Output Frequency can be selected by direct
MHz, VOR paired and TACAN channel designation.

∆F Capability

The selected frequency can be varied ±9.99 MHz in 0.01 MHz
increments.

Manual/Automatic Stepping

The selected frequency can be automatically varied in 1 MHz incre­ments.

Suppressor ON/OFF

The suppressor pulse output may be switched ON or OFF and the
level adjusted from the front panel.

DME MODE

Range Delay

Switch selectable -1.00 to 399.90 NMi

Velocity

Select inbound or outbound. Inbound and outbound velocity decre­ments range to 0 NM, then increments range 9990 KTS.

Acceleration

Non-zero acceleration decrements the selected velocity to 0 KTS,
then increments velocity to 9990 KTS.

Squitter

Digitally implemented to provide stable rate distribution and
repeatability

TACAN Simulation

When TACAN/On is selected, output pulses are AM modulated with
15 and 135 Hz signals.

Echo Pulses

Front panel selectable

Transmitter Frequency Discriminator

View frequency variation within the measured pulse

Transmitter Power Meter

Transmitter power of P

or P2in DME Mode and/or F1or F2in XPDR

1

Mode may be selected and displayed on the front panel.

Ident Pulses

Select continuous pulse or Morse code from front panel

Pulse Characteristics

DME Pulses are formed by filtering, which provides superior repre­sentation of Gaussian shaped pulses.

DME Serial Data Interface

The serial BCD distance word is generated to correspond to the
range distance programmed in the test set. This serial BCD word is
available at the back panel through a 25 pin D type connector.

Frequency Channelling

The 2-out-of-5 VOR Paired Channel Frequency is available for con­trol of the DME UUT when the test set is in the automatic frequen­cy stepping mode.

ARINC 568 compatible

Transponder Mode

Modes 1, 2, T, A, B, C, D, AC

and AC2 are available.

Variable Pulse Spacing

and P3pulse spacing may be varied in the “+” or “-” direction or

the front panel.

Pulse Width

The generated pulse width may be varied or selected for a calibrated
width by a front panel switch.

Side Lobe Suppression

On/Off selectable P

pulse

Interference/DBL Interrogation

The Interference pulse and double interrogation functions are com­bined in a single switch and are exclusively selectable.

UUT Pulse Spacing Detector

Transponder reply pulses are verified for proper position by selection
of a narrow window. A wide window is provided when pulse position
accuracy verification is not desired.

Suppression Recovery

Selection of double interrogation and suppressor pulse provides a sin­gle interrogation after suppressor pulse spacing may be varied by
interference/DBL interrogation switch.

UUT MEASUREMENTS

Transmitter Frequency Counter

The average frequency of one pulse in a reply (XPDR Mode) or an
interrogation (DME Mode) is counted and continuously displayed.
In the DME Mode either P
XPDR Mode the F

or F2may be counted.

ATC -1400A

Accessory Units

When interfaced with the T-1401, I-1402, S-1403DL/MLD or
SI-1404 accessory units, the ATC-1400A becomes a comprehensive
test system for TACAN, Mode 4 XPDR/RADAR and Mode S XPDR
avionics equipment. For more information see separate data sheets.

Non-Coherent SLS Option

provided on separate 200 MHz carrier, phase unsynchronized.
