User Manual - Rev AJ California Instruments9.3 Option –160: RTCA/DO-160 TestsThe RTCA/DO-160 Option is made up of both firmware that resides in the power source and theMXGui Windows application program. The firmware covers revision D and can be used fromthe 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 operateddirectly from the power source’s front panel or through the supplied MXGui program. TheRevision E tests can only be operated through the MXGui windows software. Thus, for Rev Euse, 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, pleaserefer to the Avionics Software Manual (CI part no. 4994-971 included on CDROM). Note thatfuture updates of the MXGui may include overlapping coverage for revision D in the software asthe MXGui program is designed to support all revisions. For now, revision D has no associateddata 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 GeneralThe RTCA/DO-160 option is capable of performing all sections of RTCA/DO-160D, Section 16and EUROCAE-14D / RTCA DO160D, Section 16 for the AC Source signal. A selection is madeavailable to specify the type of standard, and groups.Through out this document, Groups 1 through 3 will be used to refer to EUROCAE-14Dstandard.9.3.1.2 Initial SetupNominal parameters for the AC Power source are as follows:Output Voltage 115V L-N or 230V L-NOutput Frequency 360 Hz to 800 HzNominal parameters for the DC Power source are as follows:Output Voltage 28V or 14V L-NA setting outside these nominal values will disable the test and will prevent accessing to itsMenu screens. To access the test for the 230V L-N, the power source must be capable ofprogramming 360V.9.3.1.3 Tests PerformedAvailable tests are divided into Normal, Abnormal and Emergency.9.3.1.3.1 NORMAL STATEAC Source:1. Normal State Voltage and Frequency test2. Voltage unbalance test3. Waveform Distortion test4. Voltage Modulation testMX Series 191
