8 CHANNEL SELF-TEST (@@Fa)
The VP GPS receiver user has the ability to perform an extensive
self-test. The tests that are accomplished during the commanded
self-test are as follows:
• ROM Checksum
• RAM
• EEPROM
• Correlator IC
• SPI port communications with DCXO
• SPI port communications with RTC and Time increment
• SCI communication is verified operational if the RS-232 port is active
The output of the self-test command is a 16-bit field, where each bit of
the field represents the go/no-go condition of the particular item tested.
When the self-test is initiated the VP automatically goes into Idle mode.
The self-test may take up to ten seconds to execute. Once the self-test is
complete, the VP remains in Idle mode until commanded back into Fix
mode by the user. The date, time, position, almanac, and ephemeris
information is all retained.
