Subject: | TWP/KAZR/C1 - 16.56 GHz PLO failure |
DataStreams: | twpkazrauxC1.a0, twpkazrgeC1.a1, twpkazrhiC1.a1
|
Description: | The TWTA failed. It was replaced and after some troubleshooting, we found that the 16.56
GHz Phased Lock Oscillator (PLO) was bad. Instrument returned to service 20130712. |
Suggestions: | Do not use the data during this period. |
