This self test includes two different RF-supply self tests…one for Vinku and one for Hinku:
RF_SUPPLY_TEST (VINKU) (83) tests the functionality of Vinku’s bias block, regulators, reference voltage
line and, supply connections.
If these fail, all other Vinku tests can/will fail. Also many Hinku tests can be affected and can’t be
trusted.
RF_SUPPLY_TEST (HINKU) (83) tests the functionality of Hinku’s bias block, regulators, reference voltage
line and, supply connections.
If these fail, all other Hinku tests can/will fail and can’t be trusted.
Error code for this self test is given in format:
•
