Assessing Receiver Health ________________________________
This query causes an internal selftest and the response indicates whether any
errors were detected. This test takes about 40 seconds to complete.
Error -330, “Self test failed” is generated if the selftest fails.
NOTE Manual operation of internal diagnostics will affect normal Receiver
operation, including disruption of any or all of the following: GPS satellite
tracking, reference oscillator frequency, 1 PPS output timing, and Receiver
status information. When invoked manually, any of these diagnostics should
be considered to be destructive tests.
The following elements and functions are tested:
CPU
EPROM
RAM
EEPROM
UART
QSPI
FPGA logic
Interpolators
GPS engine
Power supply levels
Reference oscillator
Response
A value of 0 indicates the tests passed, a non-zero value indicates the selftest
was not completed or was completed with errors detected.
