SAFETY FIRST: TO ALL OPERATIONS PERSONNEL
REFER ALL SERVICING OF UNIT TO QUALIFIED TECHNICAL PERSONNEL. THIS UNIT CONTAINS NO
OPERATOR SERVICEABLE PARTS.
WARNING: USING THIS EQUIPMENT IN A MANNER OTHER THAN SPECIFIED BY THE ACCOMPANYING
DOCUMENTATION MAY IMPAIR THE SAFETY PROTECTION PROVIDED BY THE EQUIPMENT.
CASE, COVER OR PANEL REMOVAL
Removing protective covers, casings or panels from this Test Set exposes the operator to electrical hazards
that can result in electrical shock or equipment damage. Do not oeprate this Test Set with the case, cover
or panels removed.
SAFETY IDENTIFICATION IN TECHNICAL MANUAL
This manual uses the following terms to draw attention to possible safety hazards, that may exist when
operating this equipment.
CAUTION:
THIS TERM IDENTIFIES CONDITIONS OR ACTIVITIES THAT, IF IGNORED, CAN RESULT IN
EQUIPMENT OR PROPERTY DAMAGE (E.G., FIRE).
WARNING: THIS TERM IDENTIFIES CONDITIONS OR ACTIVITIES THAT, IF IGNORED, CAN RESULT IN
PERSONAL INJURY OR DEATH.
SAFETY SYMBOLS IN MANUALS AND ON UNITS
CAUTION: Refer to accompanying documents. (This symbol refers to specific CAUTIONS represented on
the unit and clarified in the text.)
AC OR DC TERMINAL: Terminal that may supply or be supplied with ac or dc voltage.
DC TERMINAL: Terminal that may supply or be supplied with dc voltage.
AC TERMINAL: Terminal that may supply or be supplied with ac or alternating voltage.
SWITCH OFF: AC line power to the device is OFF.
SWITCH ON: AC line power to the device is ON.
EQUIPMENT GROUNDING PRECAUTION
Improper grounding of equipment can result in electrical shock.
USE OF PROBES
Check the specifications for the maximum voltage, current and power ratings of any connector on the Test
Set before connecting it with a probe from a terminal device. Be sure the terminal device performs within
these specifications before using it for measurement, to prevent electrical shock or damage to the
equipment.
POWER CORDS
Avoid using power cords which are frayed, broken or expose bare wiring when operating this equipment.
USE RECOMMENDED FUSES ONLY
Use only fuses specifically recommended for the equipment at the specified current and voltage ratings.
CAUTION:
SIGNAL GENERATORS CAN BE A SOURCE OF ELECTROMAGNETIC INTERFERENCE (EMI) TO
COMMUNICATION RECEIVERS. SOME TRANSMITTED SIGNALS CAN CAUSE DISRUPTION
AND INTERFERENCE TO COMMUNICATION SERVICES OUT TO A DISTANCE OF SEVERAL
MILES. USERS OF THIS EQUIPMENT SHOULD SCRUTINIZE ANY OPERATION THAT RESULTS
IN RADIATION OF A SIGNAL (DIRECTLY OR INDIRECTLY) AND SHOULD TAKE NECESSARY
PRECAUTIONS TO AVOID POTENTIAL COMMUNICATION INTERFERENCE PROBLEMS.

CAPABILITIES
1.1 GENERAL
1.2.2
The ATC-1400A-2 is designed for testing and
calibrating DME (Distance Measuring
Equipment), ATC (Air Traffic Control)
Transponder Aircraft Equipment, and ARINC
568 Digital DME Indicators. The ATC-1400A-2
operates manually using front panel controls
and switches, or remotely by ATE (Automatic
Test Equipment) control through GPIB (General
Purpose Interface Bus).

Velocity
The ATC-1400A-2 incorporates the following
features and capabilities:
Selected as inbound or outbound. Inbound
velocity decreases selected range to 0 NMi,
then increases to 400.00 NMi. Outbound
velocity increases selected range to
400.00 NMi, then decreases to 0 NMi.
