Description |
|
| 03/04/2008 | | CHANNEL 4 | AMSU A1 Channel 4 out of spec performance confirmed on 4 March 2008. |
|
| 01/19/2005 | 19:20:00 | CHANNEL 9 | AMSU-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. |
|
| 01/15/2005 | 12:00:00 | CHANNEL 9 | AMSU-A1 channels 9-14 experiencing intermittent and cyclic but significant noise since 15 Jan 05 and is seriously impacting ATOVS sounding products. |
|
| 05/10/2004 | | CHANNEL 8 | N16 AMSU-A1 channel 8 problem resolved, ground calibration problem corrected. |
|
| 05/04/2004 | | CHANNEL 8 | Data dropouts for NOAA-16 AMSU-A1 channel 8. |
|
| 04/16/2003 | 12:00:01 | CHANNEL 8 | Channel 8 gain and temperature sensitivity slowly degrading since late 2001. |
|
| 03/25/2003 | 12:00:00 | | based on capability of instrument determined it to be yellow due to loss of redundancy in PLLO. |
|
| 11/26/2002 | 21:30:00 | PLLO1 | AMSU-A1 tests - toggle power between PLLO1 and PLLO2 five times. Set PLL PWR to PLLO1. |
|
| 11/26/2002 | 21:30:00 | PLLO2 | AMSU-A1 tests - toggle power between PLLO1 and PLLO2 five times. |
|
| 11/26/2002 | 18:00:00 | PLLO1 | AMSU-A1 PLLO tests - toggle power between PLLO1 and PLLO2 six times |
|
| 11/26/2002 | 18:00:00 | PLLO2 | AMSU-A1 PLLO tests - toggle power between PLLO1 and PLLO2 six times |
|
| 11/25/2002 | 18:10:00 | PLLO1 | AMSU-A1 PLLO tests - set PLL PWR to PLLO1 and then set PLL PWR to PLLO 2 |
|
| 11/25/2002 | 18:10:00 | PLLO2 | AMSU-A1 PLLO tests - set PLL PWR to PLLO1 and then set PLL PWR to PLLO 2 |
|
| 11/23/2002 | 12:00:01 | PLLO2 | PLLO#2 lock status voltages excessively high and unit does not lock on the correct frequency |
|
| 11/21/2002 | 15:50:00 | PLLO1 | AMSU-A1 Phase Lock Loop Oscillator swapped to PLLO2 from PLLO1 |
|
| 11/21/2002 | 15:50:00 | PLLO2 | AMSU-A1 Phase Lock Loop Oscillator swapped to PLLO2 from PLLO1 |
