The ARINC568 Distance Measuring Equipment Test Simulation card and software provides an easy method for testing and verifying the correct operation of Distance Measuring Equipment (DME) display units. The product consists of a WindowsTM GUI package to enable ease of conducting the various required tests without the need to have an in depth knowledge of the ARINC interface, and a PCI ARINC568 transmitter card.

ARINC 568 Interface Card

Model  Description 
PCI-A568T1  ARINC 568 DME Test Simulation card and software

The DME Interface Test card is designed to simulate the six-wire ARINC568 interface employed by DME
display equipment.
As per the ARINC 568 specification, this interface consists of a clock, synchronization and data signals.
The card is a full plug and play product and is compliant with the PCI standard version 2.1.
The transmission bit rate is variable under software control over the frequency range of 7.0kHz to 14.0kHz.
The output amplitude of the resultant waveforms is fixed at 10V peak-peak. Label 201 is transmitted at a fixed repetition rate of 50mS. The ARINC568 signals are brought out via a 37-way filtered "D" socket connector.

Tests Provided
SSM
A Special Status Matrix combo box allows for the selection of up to four different
operational designations. These are:
00 - Valid Data,
01 - Functional Test,
10 - No Computed data and
11 - Not Assigned.
 
FREQUENCY SWEEP
A test to automatically sweep the transmitted data word bit rate from 7.0kHz to 14.0kHz and
back again has been provided to check the bandwidth reception of the DME unit under test.
Dragging the slider provided also provides manual sweep control of this frequency.

SPOT DISTANCE VALUE SELECTION
A drop down box is provided that allows for the selection of popular spot distance values.
User defined values are also permitted in this box.

RAMPING SPOT DISTANCE VALUES
This test allows for a ramp of transmitted spot distance values.
The starting value for the ramp is entered into the "Select Spot Distance" box and the ramp is
then initiated by clicking a "Run Ramp" button.

DECADE RAMP TEST A test to check for sticking adjacent decade wheels on the DME unit under
test. This test again starts from the starting value entered and will cycle each digit in turn
through 0 to 9.

VARIABLE RAMP STEP TIME
The rate of the ramp step increment can be varied between 50mS to 1 second by setting the value
in the "Set Ramp Increment" box.

TRANSMITTED VALUE
The transmitted value is always displayed in the panel provided.

PCI-A568T1 SPECIFICATION
