4 EMI TEST
As with any electronic equipment, portable or installed, it is ultimately up the user to ensure
there is no interference with existing aircraft electronic systems.
Please reference EMI/RFI Test Report DOC0593 Rev 01.000 or latest revision for testing
procedures.
The purpose of this test report is to verify that the operation of the DSAT-300 does not interfere
with basic aircraft systems and avionics.
Most of the EMI tests can be accomplished on the ground. In some cases flight-testing is
required.
If the aircraft is approved for IFR operations, then it is mandatory that interference between the
DSAT-300 and the approach aids be checked in-flight.
The existing on-board GPS should be operational and navigating with at least the minimum
compliment of satellites.
The VHF Comm. should be set to commonly used frequencies with the squelch open. VOR/DME
receivers should be selected for display.
If possible, set up a DME ramp test set on the frequencies indicated and adjust the output until
the flags are out of view.
The transponder and encoder should be monitored with ramp test equipment. Set the output of
the transponder test set to 3db above the output necessary to achieve 90% reply. If possible set
the ADF to a nearby navigation station.
