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
MXGui Windows application program. The firmware covers revision D and can be used from the
front panel or under MXGui control. Revision E is implemented through the MXGui 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 MXGui program. The
Revision E tests can only be operated through the MXGui 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 MXGui, please
refer to the Avionics Software Manual (CI part no. 4994-971 included on CDROM). Note that
future updates of the MXGui may include overlapping coverage for revision D in the software as
the MXGui program is designed to support all revisions. For now, revision D has no associated
data files in the MXGui but does have it’s own user interface control screen.
9.3.1 Option –160: RTCA/DO160 rev D Tests (Firmware)
9.3.1.1 General
The RTCA/DO-160 option is capable of performing all sections of RTCA/DO-160D, Section 16
and EUROCAE-14D / RTCA DO160D, Section 16 for the AC Source signal. A selection is made
available to specify the type of standard, and groups.
Through out this document, Groups 1 through 3 will be used to refer to EUROCAE-14D
standard.
9.3.1.2 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
A setting outside these nominal values will disable the test and will prevent accessing to its Menu
screens. To access the test for the 230V L-N, the power source must be capable of
programming 360V.
9.3.1.3 Tests Performed
Available tests are divided into Normal, Abnormal and Emergency.
9.3.1.3.1 NORMAL STATE
AC Source:
1. Normal State Voltage and Frequency test
2. Voltage unbalance test
3. Waveform Distortion test
4. Voltage Modulation test
