9.3 Option –160: RTCA/DO-160 Tests
The RTCA/DO-160 Option is made up of both firmware that resides in the power source and the
Virtual Panels Windows application program. The firmware covers revision D and can be used
from the front panel or under Virtual Panels control. Revision E is implemented through the
Virtual Panels only.
The user interface for each implementation is different. The revision D tests can be operated
directly from the power source's front panel or through the supplied Virtual Panels program. The
Revision E tests can only be operated through the Virtual Panels windows software. Thus, for
Rev E use, a Windows PC and interface – RS232, USB, LAN or GPIB (recommend) - is
required.
Section 9.3.1 covers operation of the firmware based revision D tests.
For information regarding the operation of the DO160 revision E tests with the Virtual Panels,
please refer to the Avionics Software Manual (CI part no. 4994-971 included on CDROM). Note
that future updates of the Virtual Panels may include overlapping coverage for revision D in the
software as the Virtual Panels program is designed to support all revisions. For now, revision D
has no associated data files in the Virtual Panels but does have it's own user interface control
screen.

Option –160: RTCA/DO160 rev D Tests (Firmware)
9.3.1.1
General
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 all 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.
The voltage modulation tests for Airbus ABD0100.8 are supported by this option as well. The
voltage modulation levels for the Airbus version are specified differently from DO160. All other
tests are the same for Airbus and DO160.
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.
9.3.1.2
Initial Setup
Nominal parameters for the AC Power source are as follows:
Output Voltage
Output Frequency
Note:
A setting outside these nominal values will disable the test and will prevent
access to the DO160 Menu screens. To execute all tests for the 230V L-N, the
power source must be capable of programming 360V RMS. This requires the -HV
option output range (400V). If this option is not installed, some tests will be
skipped.
115V L-N or 230V L-N
360 Hz to 800 Hz
