We were on final GNAV RNP Z 02L approach into SNA; about 2 miles south of the field. Captain was flying and I was Monitoring. We were in VMC and the Captain was hand flying the aircraft. At about 600 ft.; AGL I received an amber RA flag in my RadAlt indicating my RadAlt had failed. I immediately crosschecked with the Captain and his was still indicating correctly. Just above 500 ft. I started receiving my RadAlt indications again. I had no other indication issues until touchdown. Touchdown was uneventful with all systems working correctly.
