Table D-5 Receiver Self-Test Status Codes
Notes on Table D-5:
1. Bit 3: On OEM GPSCards, “ROM” includes all forms of non-volatile memory.
2. Bits 12-15: Flag is reset to 0 five minutes after the last overrun/overload condition has occurred.
GPSCard example:
All OK = 0000 0000 0000 1010 0000 0000 1111 1111 (binary) = 000A00FF (hexadecimal) ; using a VCTCXO oscillator.
RECEIVER STATUS - DETAILED BIT DESCRIPTIONS OF SELF-TEST
Bit 0 Antenna
1 This bit will be set good if the antenna is drawing the appropriate amount of current from the GPSCard
antenna jack.
0 If the antenna connections are shorted together then this bit will be clear (0) indicating a possible antenna
port problem.
Bit 1 L1 PLL
1When the
L1 RF downconverter passes self-test, the bit will be set to 1.
0 If a fault is detected in the
L1 RF downconverter, this bit is set to 0.
Bit 2 RAM
1 When this bit is set to 1, the receiver
RAM has passed the self-test requirements.
0 If the bit has been set to 0, then
RAM test has failed; please contact NovAtel Customer Service.
Bit 3 ROM (Note: “ROM” includes all forms of nov-volatile memory (NVM))
1 When this bit is set to 1, the receiver
ROM test has passed the self test requirements.
0 A zero bit indicates the receiver has failed the
ROM test.
