Frequency Select Modes
∆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.
Aeroflex is a leader in the design, manufacture
and marketing of Avionics test systems.
Suppressor ON/OFF
The ATC-1400A is a microprocessor-controlled
test set designed to accomplish complete testing of modern ATC Transponder and DME
equipment.
DME MODE
The suppressor pulse output may be switched ON or OFF and the
level adjusted from the front panel.
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

ATC-1400A
Pulse Characteristics
DME Pulses are formed by filtering, which provides superior representation of Gaussian shaped pulses.
DME Serial Data Interface
ARINC 568 compatible
Transponder Mode
Modes 1, 2, T, A, B, C, D, AC1 and AC2 are available.
Variable Pulse Spacing
P2 and P3 pulse spacing may be varied in the “+” or “-” direction or
may be selected to the calibrated spacing from individual switches on
the front panel.
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
P2 provided on separate 200 MHz carrier, phase unsynchronized.
(Factory or factory service center installed option.)
SPECIFICATIONS
Pulse Width
The generated pulse width may be varied or selected for a calibrated
width by a front panel switch.

OUTPUT CHARACTERISTICS
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
Overall Accuacy
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 P1 or P2 may be selected to be counted. In
XPDR Mode the F1 or F2 may be counted.
