9. Option -160: RTCA / DO-160 Rev D, E
9.1 General
Option –160 includes a firmware implementation for RTCA/DO160 revision D including change 2,
section 16. For testing to revision E, the GUI based software implementation is available. The
software based avionics tests (DO160 Rev E) are covered by a separate Avionics Software Manual, CI
P/N 4994-971, which is distributed on the same CD as this manual.
This user manual assumes that the user is familiar with the text of the relevant DO160, section 16 test
standard. No attempt is made to explain or elaborate on the actual test specification.
The RTCA/DO-160D option is capable of performing most sub-sections of RTCA/DO-160D, Section
16, RTCA/DO-160D change No2 and EUROCAE-14D / RTCA DO160D, Section 16 for the AC Source
signal. A selection is made available to specify the type of standard to be applied to the EUT and the
available EUT groups.
Throughout this document, RTCA/DO-160D change No2 will be referred to as RTCA2. Groups 1
through 3 will be used to refer to the EUROCAE-14D standard. Category A(CF), A(NF) and A(WF) will
be used to refer to the RTCA2 standard.
9.2 Initial Setup
Nominal parameters for the AC Power source are as follows:
Output Voltage
115V L-N or 230V L-N.
Output Frequency
360 Hz to 800 Hz
Nominal parameters for the DC Power source are as follows:
Output Voltage
28V or 14V L-N
Note: A setting outside these nominal values will disable the test and will prevent access to
the DO160 Menu screens.
The Compact i/iX Series has a maximum voltage range for 300Vrms. Consequently, not all tests for
230VAC nominal input voltage EUT’s can be performed.
