This test checks if the EEPROM allows read/write access. A failed test indicates a
faulty EEPROM on the microboard.
Rx Test
This test checks the receiver chain with a synthetic signal. A failed test indicates
a defect on the microboard (e.g. synthesizer, digital IF, etc).

accordingly. A failed test indicates a defect on the microboard (e.g. attenua-
tors).
