SECTION 1 - DESCRIPTION
1. GENERAL DESCRIPTION AND CAPABILITIES
1.1 DESCRIPTION
The ATC-600A is a precision simulator that
enables one person to functionality test
airborne transponder (XPDR) and distance
measuring equipment (DME) systems without
removing the systems from the aircraft.
The Test Set contains built-in signal
generators and modulators for XPDR and
selected DME frequencies. For ramp
operation, the RF output is coupled to the
airborne equipment by a remote tripod
mounted antenna system. For bench
operation, coaxial cables are required between
the Test Set and UUT.
1.2 FUNCTIONAL CAPABILITIES
The ATC-600A has the following features and
capabilities:
 The type of transponder interrogation
desired is selected from Modes A/C ALT
and A/C CODE. The A/C ALT Mode
displays the aititude code. The A/C CODE
Mode displays the pilot’s code. Code
pulses and the numerical readout are
displayed simultaneously in all modes.
 A FREQ/PWR Meter indicates peak RF
power and the transmitter frequency of the
UUT. The XPDR % RPLY/DME PRF MTR
indicates XPDR percent reply and DME
interrogation pulse repetition frequency
(PRF).
 The Interrogation Spacing Control allows
precise checking of the XPDR input pulse
decoder gate. The Framing Pulse Spacing
Control allows checking of the F2 pulse
width and position relative to F1. The
Altitude Encoder Input Connector allows
altitude display from an encoding altimeter
without a transponder.
 The DME fixed range is variable from 0 to
399.0 NM, with velocity from 50 to
2400 knots. X Channel (108.00 or
108.10 MHz paired channel) and Y Channel
(108.05 MHz paired channel) are provided.
 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 7 to 10 minutes. The
Test Set can be recycled by pressing the
PWR/BAT Switch to the BAT position.
