8. Options
8.1 RTCA/DO-160 Option
The RTCA/DO-160 Option is made up of both firmware that resides in the power source and the
CSWGui Windows application program. The firmware covers revision D, and the GUI covers
revision E.
The user interface for each implementation is different however. The revision D tests can be
operated directly from the power source’s front panel or through the supplied GUI program. The
Revision E tests can only be operated through the GUI windows software. Thus, for Rev E use,
a Windows PC and interface is required.
Section 9.1.1 covers operation of the firmware based revision D tests.
For information regarding the operation of the DO160 revision E tests with the CSWGui, please
refer to the Avionics Software Manual (CI part no. 4994-971 included on CDROM). Note that
future updates of the CSWGui may include overlapping coverage for revision D in the software
as the CSWGui program is designed to support all revisions. For now, revision D has no
associated data files in the CSWGui but does have its own unique interface control screen.
8.1.1 Option –160: RTCA/DO160 rev D Tests (Firmware)
8.1.1.1 General
The RTCA/DO-160D 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.
Throughout this document, Groups 1 through 3 will be used to refer to EUROCAE-14D standard.
8.1.1.2 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.
