Date Time Component Description
03/04/200800:00:00CHANNEL 4AMSU A1 Channel 4 out of spec performance confirmed on 4 March 2008.
01/19/200519:20:00CHANNEL 9AMSU-A1 imagery return to nominal. ATOV products again being distributed. Cause of original problem unknown but is not believed to be related to HIRS heater turnon/turnoff.
01/15/200512:00:00CHANNEL 9AMSU-A1 channels 9-14 experiencing intermittent and cyclic but significant noise since 15 Jan 05 and is seriously impacting ATOVS sounding products.
05/10/200400:00:00CHANNEL 8N16 AMSU-A1 channel 8 problem resolved, ground calibration problem corrected.
05/04/200400:00:00CHANNEL 8Data dropouts for NOAA-16 AMSU-A1 channel 8.
04/16/200300:00:01CHANNEL 8Channel 8 gain and temperature sensitivity slowly degrading since late 2001.
03/25/200312:00:00 based on capability of instrument determined it to be yellow due to loss of redundancy in PLLO.
11/26/200221:36:00PLLO1Toggle between PLLO 1 and 2 power three times. End with Primary PLLO enabled.
11/26/200221:35:00PLLO2Toggle between PLLO 1 and 2 power three times. End with Primary PLLO enabled.
11/26/200221:30:00PLLO1AMSU-A1 tests - toggle power between PLLO1 and PLLO2 five times. Set PLL PWR to PLLO1.
